This depends on where you check in, your destination and how much baggage you have. During holiday season and peak hours, please arrive at least 2 hours before departure for international flights, as many people are traveling during these periods. Remember that you also need time to get through security control and to walk to the gate. See deadlines for check-in
Please note that your baggage needs to be checked in before the same deadlines as the above. Please note that other rules may apply to charter flights.
