When you gate-check a stroller, you use it to navigate the airport and through the security checkpoint right up until the moment you board the aircraft. At the end of the jet bridge, just before entering the plane door, you fold the stroller and leave it in the designated "gate-check" area. A ground crew member then manually carries it down the stairs or via a lift and places it in a dedicated section of the cargo hold, usually last-on, first-off. Because these items aren't mixed with heavy "checked" suitcases in the main hold, they are less likely to be crushed, though they are still exposed to grease and weather. Upon landing, the crew retrieves the stroller and brings it back up to the jet bridge for you to collect as you deplane. In 2026, many parents use protective travel bags even for gate-checking to prevent scuffs. Note that for some international or "regional" flights, certain airlines may send gate-checked strollers to the baggage carousel instead of the jet bridge, so always verify with the gate agent when they hand you the "Gate Check" tag.
