Generally, you do not have to get off the plane when it refuels, provided the airline follows strict international safety protocols. In 2026, refueling with passengers on board is a common "quick turn" procedure to save time, but it requires at least one pilot to remain on the flight deck and cabin crew to stand by at their designated door pairs. Passengers are typically instructed to unfasten their seatbelts to allow for a rapid evacuation if a fire occurs and are forbidden from smoking or using electronic devices that could cause sparks. Furthermore, the aisles and emergency exits must remain completely clear of obstructions like catering carts. If the aircraft is using specific high-volatility fuels or if local airport regulations are exceptionally strict, the airline may require a full disembarkation, but for the vast majority of standard commercial flights, you can remain in your seat throughout the process.
