- How long before my flight should I arrive at the airport ?
Some airlines wait as long as possible to close their check-in; in some cases they only close 30 minutes before the scheduled departure time. Other airlines close their check-in 45 minutes to 1 hour before the scheduled departure time.
Most airlines open their check-in two to four hours before the scheduled departure time of a given flight; airlines that serve many destinations from their airport of departure are permanently open and may allow you to check in hours in advance.
Exact details on the opening and closing hours of the check-in are usually available on the airline's website or in the documents that were sent together with your ticket. If you booked your flight through a travel agent, they will normally be able to give you this information.
In general passengers are advised to arrive at check-in two hours ahead of their scheduled departure time. This is a recommendation, not an obligation.
Passengers are themselves responsible for arriving on time at the check-in desks and the boarding gate even if they are late owing to circumstances beyond their control (car broke down, public transport delays, problems with identity papers,...).
