You will need to check-in for your flight 2 hours before the scheduled departure time.
Check-in desks always close promptly, 40 minutes prior to departure. Arrive early and avoid the big queues, especially if you are flying on a low-cost airline.
Don't be late because the airline could refuse to take you, in which case you will have to pay to get another flight out. Ideally you should have completed check-in at least 1 hour before you are scheduled to take-off.
Remember passengers who present themselves later than 40 minutes prior to scheduled time of departure will not be accepted for carriage and will forfeit their seats. No refund will be given.
