For a summer city break, a few days by the sea, or a multi city adventure, one-bag travel can make the entire journey feel easier. It can also help you keep the cost under control.
Kiwi.com helps travellers discover affordable flights and unique route combinations across hundreds of airlines. By combining flights from airlines that do not usually cooperate, Kiwi.com can provide more ways to reach your destination, including self-transfer routes that may cost less than more traditional options.
Travelling with one bag can make these flexible journeys even simpler. Once you know what you genuinely need to bring, you can compare baggage options, review the Kiwi.com fees included in the total price, and choose the fare that works best for your trip.
Kiwi.com makes it easier to understand the full price and available options before you book, so you can plan the trip confidently. The aim is not to spend your holiday thinking about baggage rules. It is to make a few smart choices before you leave, so you can travel with less and enjoy more.
Why one-bag travel makes sense this summer
Summer trips often start with a simple idea: a few nights somewhere sunny, a last-minute city break, or a week away with more than one stop. Then the packing begins, and it is surprisingly easy to bring far more than you need.
You start thinking about a separate outfit for every possible weather forecast, shoes for plans that may never happen, toiletries that take up half the bag, and a book you probably will not open. Before long, the second jacket has made its way into the pile, just in case.
Travelling with one bag encourages you to decide what the trip is actually going to look like. That can be useful. You move more easily through busy airports, spend less time waiting, and have fewer belongings to keep track of when the journey includes buses, trains, or separate flights.
It can also make comparing cheap flights more straightforward. Once you know what you genuinely need to bring, it is easier to understand which fare offers the best value for the journey.
The difference between a personal item and a cabin bag
Before booking, check exactly what the airline allows you to bring. A personal item is usually a small bag designed to fit under the seat in front of you, such as a compact backpack, handbag, or travel bag.
A cabin bag is generally larger and usually needs to fit in the overhead locker. Some cheap fares include a personal item but offer the option to add a cabin bag, while other tickets may include both. Checked baggage is a separate category again: it travels in the aircraft hold and usually needs to be dropped off before security.
The details vary between airlines. This matters even if every flight appears within the same booking. If your itinerary combines different airlines, check the rules for all the flights so you can choose the right baggage option from the beginning.
Your first flight may include a cabin bag, while the second flight only includes a personal item. Kiwi.com makes it easier to review the journey and select an option that suits the full itinerary.
Check the minimum bag size before you book
If you are planning a one-bag trip, one of the first questions to ask is whether your backpack or travel bag will fit within the allowance for every flight.
There have been moves towards making baggage rules clearer across Europe. Airlines for Europe members have adopted a minimum personal-bag standard of 40 × 30 × 15 cm within basic fares. This refers to a small bag designed to fit beneath the seat in front of you.
There are also ongoing discussions around wider EU passenger-rights rules for cabin baggage. However, this does not mean every airline now follows exactly the same policy. Some carriers allow a larger under-seat bag, while others include an additional cabin bag within the ticket price or offer one as a paid extra. The allowance can also depend on the fare selected.
As a general guide, the published allowances from several popular airlines include:
- Ryanair: One small personal bag up to 40 × 30 × 20 cm is included with all fares. A second cabin bag up to 55 × 40 × 20 cm and 10 kg is available with Priority and selected options.
- easyJet: One small under-seat cabin bag up to 45 × 36 × 20 cm is included. A larger cabin bag up to 56 × 45 × 25 cm is available with selected options.
- Wizz Air: One carry-on bag up to 40 × 30 × 20 cm and 10 kg is included. A trolley bag up to 55 × 40 × 23 cm and 10 kg is available with WIZZ Priority.
- Jet2.com: A small under-seat bag up to 40 × 30 × 20 cm is allowed. One piece of hand luggage up to 56 × 45 × 25 cm and 10 kg is also included.
- British Airways: One handbag or backpack up to 40 × 30 × 15 cm is included. One cabin bag up to 56 × 45 × 25 cm is also included.
Baggage policies can change, so always review the latest rules before booking and check again shortly before you travel. Include the bag’s handles and wheels when measuring it where the airline requires this.
If your journey combines separate flights, look at every leg individually. A backpack that fits comfortably within the first airline’s allowance may be too large for the second. Using the smallest allowance across the full itinerary as your guide can help you avoid unexpected charges at the airport.
What do Kiwi.com fees include?
Kiwi.com is committed to making the booking process clear and transparent. When you book a trip, the total price displayed in your chosen currency includes the carrier’s ticket price and the Kiwi.com service fees .
The service fee helps Kiwi.com provide its smart flight-search solutions, manage your booking, process payments securely, and offer customer support throughout the journey.
Depending on your plans, you can also choose additional options such as baggage, seat selection, or the Kiwi.com Guarantee . These choices are presented during the booking process, so you can build a trip that fits both your travel style and your budget.
There are no hidden fees. The goal is to make it easier to understand the full price before you book and choose the option that feels right for your trip.
If you are travelling with one small backpack, the most basic fare may be all you need. If you want a cabin bag or checked baggage, you can include that in the comparison and select the option that works best for the journey.
Start with the bag, then search the flights
It may sound backwards. Most people search flights first and think about packing later. But if keeping the trip affordable matters, decide what you are realistically bringing before you book.
Could everything fit into a small backpack? Would a cabin bag make the trip more comfortable? Do you need checked baggage?
For a two-night break, a personal item might be enough. For a week away, you may prefer a cabin bag. For a longer trip with multiple destinations, travelling light could make moving around much easier.
There is no prize for bringing the smallest bag possible. The aim is to choose the luggage that fits the trip without paying for space you will not use.
The one-bag test
Lay everything out before you book, rather than waiting until the night before the flight. Start with the essentials: travel documents, a phone charger, medication, toiletries, underwear, a layer for cooler evenings, comfortable shoes, and clothing that works in more than one combination.
Then look at what remains. If the bag closes easily, a personal item or cabin bag may be enough. If you would feel more comfortable with additional room, choose a larger allowance from the beginning.
Remember that the return trip can be different. You may pick up a souvenir, buy something at the destination, or discover that your clothes do not fold quite as neatly on the way home.
A little spare room can make the journey easier.
Pack for the itinerary you have
One-bag travel becomes much easier when you stop packing for imaginary plans. A summer city break usually needs comfortable clothing and shoes you can walk in. A beach trip needs swimwear, something light for the evening, and sun protection.
A multi city trip calls for clothes that can be re-worn and layered. A work-from-anywhere trip may require a laptop and a slightly more organised setup.
Think about what you will actually do and pack around that. One pair of versatile shoes is often more useful than several pairs that only work with one outfit. A light layer can be more practical than a bulky jacket, while travel-sized toiletries can free up valuable space.
The point is not to make the trip feel restrictive. It is to bring the things that add value and leave the rest at home.
When a cabin bag is worth paying for
A cabin bag can be a useful middle ground. You have more room than a small personal item, but you can still avoid checking luggage into the aircraft hold and waiting at the baggage carousel.
It can also make a connection easier if the trip includes separate flights. Keeping your bag with you means there is less to collect and fewer queues to navigate during the journey.
That does not mean a cabin bag is always the right choice. For a short trip, the additional space may not be necessary. For a longer holiday, it may make the journey much more comfortable.
Compare the baggage fees , look at the ticket price, and think about how much you value moving quickly through the airport. Then choose the option that suits the journey.
When checked baggage makes more sense
Travelling light is useful, but it is not a rule. Sometimes checked baggage is the sensible choice.
You may be travelling for several weeks, need specialist equipment, or be visiting a destination with different temperatures. You may be travelling with children or simply want more space.
If checked baggage makes the trip more comfortable, include it from the beginning. Kiwi.com allows you to compare the available baggage choices as part of the booking, helping you understand the full price before you travel.
Check the baggage policies for each airline. If the itinerary includes a self transfer, confirm whether you need to collect and re check the bag during the connection, as this can affect how much transfer time you need.
Cheap flights still need to fit the trip
Finding cheap flights can feel like a small victory, and sometimes it is. A little extra planning can help you make the most of the deal.
Check the airport, review the departure time, and look at the baggage allowance. Think about the journey from your home to the terminal and the transfer from the arrival airport to your final destination.
A very early first flight may require an additional transfer plan. A late arrival may mean checking local transport times in advance. A secondary airport could still be a great option if the route into the city is convenient.
These details help you compare the journey properly. A cheap fare is most useful when it supports the trip you want to take.
Search wider than one airline
Booking directly with an airline can be a straightforward choice for a simple route, but it does not always reveal every possible option.
Kiwi.com searches flights across hundreds of airlines, creating more ways for travellers to reach their destination. This can help you find cheap flights, alternative flights, and route combinations that may not appear when you search one carrier at a time.
Sometimes the answer is a direct flight. Sometimes it is a round trip with different airlines on the outbound and return journeys. In other cases, a self transfer or multi city trip may make more sense.
The right route depends on what matters most to you: price, time, convenience, baggage, the airport, or the final destination. A wider search gives you more ways to decide.
Why one bag can make a self transfer easier
One of Kiwi.com’s most popular features is self-transfer. This involves creating a custom itinerary by combining separate flights from airlines that do not usually cooperate with one another.
Your first flight may take you to a major airport, while your second flight continues to the final destination with another carrier. This innovative approach opens up more route combinations and can help travellers find lower prices.
A self transfer works differently from a traditional connection booked on one airline ticket, so a little preparation can help the journey feel even smoother.
In many cases, travellers with checked baggage need to collect their bags at the connecting airport, exit the transit area, and re check them before the next flight. You may also need to pass through immigration, customs, or security.
This is where travelling with a personal item or cabin bag can make the experience particularly easy. With one bag kept close, you can move through the airport more quickly and continue the journey without waiting at the baggage carousel.
Give separate flights enough time
Self-transfer routes can unlock affordable flights and unique journeys that may not be available through a standard airline booking. When comparing these options, allow enough time to make the connection comfortably.
As a general guide, allow at least two to three hours for domestic connections. For international routes that require customs, four to six hours can provide more breathing room.
Check whether the flights use the same terminal and whether you need to pass through immigration or security. Before travelling, also review any visa requirements for the countries included in the itinerary, as these remain the traveller’s responsibility.
If you are bringing checked baggage, make sure there is enough time to collect and re check the bag before the next flight.
A longer connection can be a worthwhile trade-off. You have time to find the next gate, grab something to eat, and begin the second leg without rushing.
A one-bag trip can open up more airports
Travelling with one bag gives you more freedom to consider alternative airports. You do not need to think about collecting checked baggage after every flight, and you can move more easily between terminals.
A train or coach connection may feel more manageable. A smaller airport could also be worth considering if the route offers a better price.
Compare the complete journey and look at the available transport options. A secondary airport can be a smart choice when the transfer is simple and the overall route gives you better value.
The airport is not just a line on the ticket. It is part of the travel experience.
Multi city travel is easier when you pack light
A multi city trip has a different rhythm from a standard holiday. You are not unpacking once and staying in the same place.
You may move between cities by train, use budget airlines for one leg, and take a different carrier for the next flight. You could fly into one destination and return home from another.
That can be a smart way to see more without retracing your steps. It can also help you compare more affordable flights.
One bag makes that type of journey easier. You can leave an airport quickly, board a train without wrestling with a large suitcase, and walk to your accommodation if it is nearby.
You spend less time managing your belongings and more time enjoying the places you travelled to see.
Try a simple multi city route first
A multi city trip does not have to involve six countries and an ambitious spreadsheet. Start with something simple.
Fly into one city and spend a few days there. Continue to a second destination by train or with another flight, then return home from the second city.
That can work particularly well in regions where several destinations are close together. It may also reveal better flight prices than a standard return ticket.
If the second leg involves a flight, compare the baggage policies again. The first airline and second airline may not treat a personal item or cabin bag in the same way.
Keep the trip light enough to stay flexible.
Google Flights can help you understand the market
Many travellers begin with Google Flights. It can be useful for exploring dates and getting a general feel for flight prices.
You may notice that flying one day earlier changes the price. You might find that a nearby airport offers lower prices or discover that a round trip is not the only option worth considering.
From there, Kiwi.com can help you explore different airlines and unique routes, including separate flights and self-transfer itineraries.
The tools can serve different purposes. You do not need to treat flight search as a loyalty test.
The aim is to understand the options well enough to choose a trip that works.
Use Price Alerts when your plans are flexible
Sometimes you are ready to travel but not quite ready to book. You may be deciding between several cities, watching more than one weekend, or looking for a summer break without knowing exactly where it will take you.
Price Alerts can help. Track the routes you are interested in and receive notifications when prices drop.
That saves you from repeating the same flight search every morning. It also gives you more time to compare the options and book when the price feels right.
Once a booking is confirmed, the price is locked in. You will not be charged more than the amount paid at the time of booking, even if the flight price changes later.
What about low cost airlines?
Low cost airlines can help make travel more affordable and are often an important part of finding cheap fares.
The lowest available ticket may include a small backpack rather than a cabin bag. Checked baggage may be available as an additional option, seat selection can be optional, and airport check in rules may differ.
This gives travellers the flexibility to build the booking around the way they want to travel.
A low-cost fare can be an excellent deal when it matches your plans. If you are comfortable with one small bag, flexible about assigned seats, and prepared to check in online, the ticket may suit you perfectly.
If you want extra luggage or a specific seat, you can include those choices in the price comparison.
Different airlines can have different baggage policies
Baggage policies can vary across regions as well as airlines. A traveller using AirAsia for one part of a longer trip may encounter different rules from someone taking a short European route.
A domestic flight may work differently from an international connection. A low-cost airline may offer several baggage options, while another carrier may include more in the original ticket price.
Check each leg, look at the weight and size limits, and confirm whether the bag belongs under the seat or in the overhead locker.
Making sure the allowance suits the full itinerary can help the journey feel easier from the moment you leave home.
Seat selection: decide whether it matters to you
Seat selection is another choice that depends on the traveller. Some people want a window seat, others prefer an aisle, and some want to sit near the front of the aircraft.
Other travellers are happy to accept the assigned seats and keep the price lower. If you are travelling with children or as a group, sitting together may matter more. If you are flying alone for a short break, it may not.
There is no universal right answer. Review the seat selection options, add the cost if it improves the journey for you, and skip it if it does not.
A smart booking is not necessarily the booking with no extras. It is the one where every extra has a reason to be there.
Check in before you reach the airport
One-bag travel can make the airport much easier. A little preparation can make the travel day feel even smoother.
Check in online where required. Keep the booking number accessible, save the boarding passes, download them to your phone, and take a screenshot in case the airport signal is unreliable.
Re check the terminal before leaving home. If the itinerary includes separate flights, make sure you know whether each airline has its own check in process.
Some budget airlines may have different rules for airport check in. Understanding the process in advance means you can arrive at the terminal feeling prepared.
How the Kiwi.com Guarantee can help
Kiwi.com’s mission is to make travel simpler and help customers feel confident from booking to arrival. For travellers who want additional support, the Kiwi.com Guarantee is a premium package of services designed to provide greater protection throughout the journey.
This can be particularly valuable for more complex itineraries involving a self transfer.
The Kiwi.com Guarantee includes automatic check in for every flight in the itinerary. Simply provide your passport or ID details at least 24 hours before departure, and Kiwi.com will check you in with each airline once online check in becomes available.
Your boarding passes will then be sent directly to the Kiwi.com app, ready for you at the airport.
The Kiwi.com Guarantee also includes 24/7 support and Disruption Protection , helping you travel with confidence even when plans change unexpectedly.
Connection Protection and the next flight
Connection Protection is a key part of the support Kiwi.com provides for self-transfer routes.
If a delay, cancellation, or schedule change to the first flight causes you to miss the second leg of the trip, the airline operating the first flight may not be responsible for the separate connecting flight.
With Connection Protection through the Kiwi.com Guarantee, Kiwi.com can provide immediate options to help you continue the journey. This can include Kiwi.com Credit, which you can use to book an alternative flight, or support with requesting a refund from the airline.
This gives travellers the freedom to explore creative and affordable routes while knowing that additional support is available if an eligible disruption affects the itinerary.
What happens if a flight is cancelled?
Flight cancellations can be stressful, but Kiwi.com aims to make the next steps as clear as possible.
If an airline cancels or significantly changes an eligible trip and you have the Kiwi.com Guarantee, you can receive Kiwi.com Credit instantly. This can be used to book a new flight straight away or saved for a future journey.
If you would prefer, Kiwi.com can also request a refund from the airline on your behalf.
Without the Kiwi.com Guarantee, Kiwi.com can still submit a refund request to the airline for you. The outcome and processing time will depend on the airline and its policies.
The available options can be reviewed and managed online through your Kiwi.com account, helping you make the right decision for your travel plans.
If your travel plans change
Sometimes the airline changes the schedule. Sometimes your own plans change.
The available options depend on the ticket type, the airline policies, and whether you selected the Kiwi.com Guarantee or another additional protection service.
You can manage the process through your Kiwi.com account on the website or in the app. Open the relevant trip, review the available cancellation or refund options, and choose the solution that works best for you.
This keeps the booking details in one place and helps make the next steps clearer.
Keep the whole journey in the Kiwi.com app
A one-bag trip feels easiest when the travel details are organised too. The Kiwi.com app helps you keep your itinerary close throughout the journey.
Use it to access boarding passes, review flight details, receive notifications, and keep your booking information together.
This becomes particularly helpful when the journey includes separate flights, different airlines, or more than one booking number.
You can also manage changes, review refund options, and submit requests through your Kiwi.com account. Support is available through the website or app, helping you find the information you need without losing track of the trip.
The five-minute check before you book
Before paying, take five minutes to review the journey. Look at the total ticket price and the Kiwi.com fees included in the booking.
Check whether the fare includes a personal item, cabin bag, or checked baggage. Confirm the baggage policies for all the flights and choose an allowance that works for the full itinerary.
Review the departure and arrival airports, look at the connection time, and check whether the route includes separate flights or a self transfer. If you need checked baggage, leave enough time to collect and re check it during the connection.
Think about whether you want seat selection or the additional support provided through the Kiwi.com Guarantee. It is also worth reviewing the ticket type and change options, so you understand what is available if your plans change later.
Then compare the full price with the other routes you found and choose the journey that works best for you.
One bag, more freedom
The appeal of one-bag travel is not only saving money. It is the feeling of being able to move.
You step off the first flight and continue the journey. You arrive in a new city without waiting beside a baggage carousel. You board a train without lifting a huge suitcase onto the luggage rack.
You can explore self-transfer flights and multi city routes without making the trip feel like hard work.
Kiwi.com helps travellers find affordable flights, compare more route combinations, and understand the available options clearly before booking.
Choose the baggage allowance that suits your plans. Give yourself enough time for a self transfer. Keep your boarding passes close in the Kiwi.com app.
Then pack the things you genuinely need, zip the bag, and go.
