How does checked baggage work when switching airlines?

It depends on how your ticket was booked. If your flights were booked under one ticket, your bags will be checked through to your final destination. If your flights were booked under separate tickets, you will need to collect your bags and recheck them before your connecting flight.



If you have booked a single "interline" or "codeshare" itinerary, your checked baggage is typically checked through to your final destination, and the airlines handle the transfer behind the scenes. However, in 2026, "self-transfer" bookings (buying two separate tickets on different airlines) are more common to save money, and these require you to claim and re-check your bags. In this scenario, you must exit the secure area, collect your luggage from the carousel, go to the second airline’s check-in counter, and pass through security again. This is particularly important for international connections where you may need to clear customs at the transfer point. Additionally, if your first flight is delayed and you miss your second "separate" flight, the second airline is not obligated to help you, making a 3-to-4-hour buffer essential for these types of multi-airline journeys.

In theory, absolutely! In practice, whether you leave the airport during a layover is tricky.

Luggage fees
The sure-fire way to avoid this fee is to travel with a carry-on bag only. However, if you simply cannot do without your checked luggage, try to pay for the bag online, as it is typically much cheaper to purchase your bag on the airline's website rather than pay up front at the check-in counter.
