We strictly recommend you to arrive at the airport in advance. Check-in for domestic flights usually ends in 30 minutes before departure and check-in for international flights - in 40 minutes before departure. However, some airlines may have different check-in rules, that is why we advise you to read your airline rules in advance.
Before going to the airport make sure you take ticket (or printed e-ticket) and passport, birth certificate and other necessary travel documents for children.
Check- in desks for domestic and international flights are located after security control points.
