If you booked a trip and have enough layover time and no “hidden city” stop, please review the checked baggage conditions of the carriers. It may be possible to add baggage through carriers directly, or at the airport.
If you haven’t booked your trip, but need baggage or plan to travel with a wheelchair or stroller, please choose an itinerary with a longer layover time. Carriers usually put these items into the cargo hold, and you may need more time to wait for them.
