In most cases in 2026, you do not get off the plane during a technical refueling stop, especially if it's an unscheduled stop due to high headwinds. Airlines prefer to keep passengers on board to ensure a quick "turnaround" and to avoid complex immigration or security issues in a country where you might not have a visa. During refueling with passengers on board, strict safety protocols are followed: the "Fasten Seatbelt" sign must be turned off, cabin crew must be positioned at every door, and at least one exit must be connected to a jet bridge or stairs. You are instructed to keep your seatbelt unfastened so that you can evacuate instantly in the rare event of a fire. The only common exception in 2026 is at certain hubs like Shannon (Ireland) for pre-clearance flights, where you might be asked to deplane with your carry-on to clear US customs while the aircraft is serviced.
