Can I check in at the airport if I complete online check-in?
Yes. Online check-in handles passenger and boarding pass processing, but you must still visit a baggage drop desk at the airport to physically check in any luggage.
What documents do I need for check-in?
Bring a valid passport or national ID card matching your booking. For international flights, ensure your passport meets validity requirements for your destination country.
