Rechecking bags during a layover is a process that depends primarily on whether your journey is domestic or international and if your flights were booked on a single ticket. For most domestic-to-domestic connections on a single itinerary, your bags are "checked through" to your final destination, and you do not need to do anything. However, the "gold standard" for international arrivals in countries like the United States or Canada is that you must collect your luggage after clearing immigration, even if you are just passing through to another city. After retrieving your suitcase from the carousel and passing through customs, you will look for a dedicated "Baggage Recheck" counter located just outside the customs hall. These counters are specifically designed for transit passengers; because your bag is already tagged with its final destination, the agent simply scans it and places it back onto the conveyor belt. If you booked two separate tickets on different airlines, you must go to the main departures hall, check in as a new passenger, and pay any relevant baggage fees again, making it vital to allow at least three to four hours for such "self-transfers" in 2026.
