Practical tip: Complete online check-in as early as possible after the 24-hour window opens to secure preferred seating and avoid last-minute airport queues, especially during peak travel times.
Can I check in at the airport if I miss the online window?
Yes, airport check-in counters are available for passengers who cannot or prefer not to check in online. Arrive at the airport early to allow sufficient time for baggage processing and security screening.
What documents do I need to check in?
Have your passport or valid travel identification and booking confirmation ready. For international flights, ensure your passport is valid for the duration of your stay. Additional visas or travel permits may be required depending on your destination-verify entry requirements with your destination country's authorities.
