Same-day return flights can be cheaper than a normal return, but only if you book them in advance and on the right kind of route. On low-cost airlines, each flight is priced separately, so flying out at 7am and back at 9pm costs roughly the same as two one-way tickets on any other day. Often that’s very little. What isn’t usually cheaper is booking a flight on the day you travel. Last-minute fares tend to be among the most expensive, because the cheapest seats sell first.
In this article
Two questions hide behind “same-day flights”, so this guide covers both: flying there and back in one day, and buying a ticket on the day of departure.
Key takeaways
Same-day returns are often good value. On short, low-cost routes booked weeks ahead, a day trip can cost less than a normal return and you save on a hotel.
Booking on the day you fly is usually more expensive. It is possible on most flights, but last-minute fares tend to be among the most expensive because the cheapest seats sell first.
The cheapest approach is to plan. Book early, fly the first flight out and the last flight back, take hand luggage only, and stick to flights under about two hours.
You can book a flight on the same day. Airlines sell seats until shortly before check-in closes, so the limit is time rather than availability.
Book two to eight weeks ahead. For short-haul trips, booking a few weeks in advance usually gets you the lower fare tiers on both flights.

Same-Day Return vs Same-Day Booking
| Same-day return (day trip) | Booking on the day of departure | |
|---|---|---|
| What it means | Fly out and back on the same date | Buy a ticket a few hours before takeoff |
| Is it cheaper? | Often, when booked in advance | Rarely |
| Main saving | No hotel, no extra night of spending | None guaranteed, only convenience |
| Best for | City day trips, meetings, events | Emergencies, sudden plans |
Why Same-Day Return Flights Can Be Cheap
Low-Cost Airlines Price Each Flight Separately
Low-cost carriers sell every flight on its own. A return ticket is simply two one-way fares added together, so there’s no penalty for coming back the same day. If the 6:30am departure and the 9:30pm return are both lightly booked, the pair can cost less than a single weekend flight.
Traditional airlines sometimes work differently, particularly on business routes. Their cheapest return fares can come with conditions on the length of stay, while flexible fares aimed at business travellers are priced higher. That’s why a same-day return on a full-service airline between two business hubs can cost more than the same trip over a few nights. Always compare it with two one-way tickets.
You Skip the Biggest Cost: The Hotel
Even when the flights cost the same as a regular trip, a day trip removes the most expensive part of most city breaks, a night’s accommodation. Add in fewer meals out and no luggage to check, and a day trip is often the cheapest way to see a new city.
Early and Late Flights Are Often the Cheapest
The flights that make day trips possible, the first departure of the morning and the last flight home, are often the least popular with other travellers, so they can be cheaper. Our guide on how morning flights help you beat delays and high prices explains why early departures are worth the alarm clock.
Are Same-Day Flights Cheaper If You Book on the Day?
Usually not. Airlines sell seats in price tiers: the lowest fares go first, and prices tend to climb as the plane fills and departure gets closer. By the day of the flight, the seats left are often the most expensive ones. Travellers booking at the last minute usually include business travellers and people with urgent plans, who can’t wait for a better price.
That doesn’t mean a good day-of fare never appears. It can happen on quiet routes, off-peak days, or flights that are still well below capacity. It’s just not something to rely on. As our guide to whether flights get cheaper last minute puts it, last-minute deals are the exception rather than the rule.
If you do need to fly today, search last-minute flights across every airline on the route at once rather than checking each airline separately. Prices for the same trip can vary a lot between carriers.
Can You Book a Flight on the Same Day?
Yes. You can book most flights on the day of departure, online or at the airport, as long as there are seats left. The limit is time rather than availability. Airlines and booking sites stop selling a flight shortly before check-in closes, and the cut-off varies by airline and route.
To book a same-day flight without problems:
- Book as early in the day as you can. Fares and seat availability usually get worse as the departure time approaches.
- Travel with hand luggage only. You can skip bag drop, which often closes earlier than check-in.
- Check in online straight after booking. Some low-cost airlines charge for airport check-in.
- Leave enough time for security. A same-day booking doesn’t get you through the queue any faster.
- Have your ID or passport ready. International same-day bookings still need the right documents.
Already booked, but want an earlier or later flight on the same day? Many airlines offer same-day standby or confirmed changes, sometimes for a fee. Our guide to same-day flight changes lists the policies airline by airline.
How to Get Cheap Same-Day Return Flights
Book Two to Eight Weeks Ahead
The biggest saving comes from planning, not waiting. For short-haul trips, booking a few weeks in advance usually gets you the lower fare tiers on both flights. Our guide on when to book and when to wait goes into the timing in more detail.
Choose Short Routes With Frequent Flights
A day trip only works if the flights leave enough time on the ground. Look for routes of about two hours or less, with an early departure and a late return. Good examples include:

Mix Airlines Out and Back
The cheapest outbound and the cheapest return are often on different airlines. On Kiwi.com you can combine them in one search, for example flying out with one low-cost carrier and back with another, instead of paying more to stay with the same airline both ways.
Be Flexible on the Day of the Week
Midweek dates are usually cheaper than Fridays and Sundays. If your day trip isn’t tied to a specific event, check a few dates before you book. Our guide to the cheapest day to fly shows which days tend to be quietest.
Pack for the Day, Not the Trip
A day trip means no checked bag. Stick to the free personal item or a small cabin bag and you avoid one of the easiest add-on fees to rack up. See our guide to personal items vs carry-on bags to check what fits.
How Much Time You’ll Actually Get on the Ground
A day trip by plane needs a quick bit of maths before you book. For a typical short-haul day trip:
| Step | Time |
|---|---|
| Early flight departs | 7:00 |
| Land after a 1.5-hour flight | 8:30 |
| Clear the airport and get into the city | 9:30–10:00 |
| Leave the city for the airport | 18:00 |
| Arrive at the airport (about 2 hours before) | 19:00 |
| Evening flight departs | 21:00 |
That gives you around eight hours to explore. Cities with fast airport-to-centre links, like Dublin, Amsterdam, and Copenhagen, give you the most time. Keep a return flight later in the evening as a buffer, particularly if you’re connecting or crossing a border with passport checks.
Tip: check the time difference. Flying east from the UK to mainland Europe, you lose an hour on the way out and gain it back on the way home. That shortens your day in the city, so plan your return flight with local time in mind.

Same Day Return FAQs
What happens if my outbound flight is delayed on a day trip?
A long delay eats straight into your time on the ground, and your return flight won’t wait. If the delay is so long that the trip isn’t worth taking, speak to the airline before you fly. Depending on the route and the length of the delay, you may be entitled to a refund under passenger rights rules like EU261.
Do I need a passport for a same-day international flight?
Yes. A day trip abroad needs the same documents as a longer stay, including a valid passport, and any visa or travel authorisation your destination requires. The only exceptions are where no passport is legally needed, such as for British citizens travelling to Ireland, and even then many airlines still ask for photo ID.
Is a day trip by plane worth it compared with the train?
On routes under about two and a half hours by rail, such as London to Paris or Brussels, the train often wins once you add airport time and transfers. Flying makes more sense when the rail journey is four hours or more, or when you’re crossing water, such as London to Dublin.
Can I earn airline miles on same-day return flights?
Yes. A same-day return earns miles or points in the same way as any other trip, based on the airline’s loyalty programme rules. Low-cost carriers generally don’t run traditional mileage programmes, so check before you book if collecting points matters to you.
Is it cheaper to book two one-way tickets for a day trip?
It often is, especially if different airlines have the cheapest flight in each direction. Kiwi.com automatically compares combinations of one-way flights with regular returns, so you’ll see the cheapest option either way.
