What happens if your bag is on a different flight?

The agent at check-in will usually ask if you want your luggage checked through to your last stop. You'll also receive boarding passes for both flights when you first check-in, so all you will need to do is find your gate at your connecting airport and your bags will automatically follow.



When your checked bag is mistakenly loaded onto a different flight—a situation known as "mishandled baggage"—airlines follow a standardized recovery protocol. In 2026, most major carriers utilize real-time GPS or RFID tracking, allowing them to locate the "stray" bag almost instantly. Once the bag arrives at its actual location, it is typically sent to the Baggage Service Office (BSO). The airline is then legally responsible for delivering the bag to your home or hotel free of charge, often using local courier services. Under international regulations like the Montreal Convention, you are entitled to "reasonable" reimbursement for essential items (toiletries and basic clothing) purchased while waiting for your bag. If the bag is not located within 21 days, it is declared "lost," and you can file a formal claim for the value of the contents (up to approximately $1,700–$3,800 depending on the route). Always file a Property Irregularity Report (PIR) before leaving the airport to initiate the tracking process.
