When preparing to fly with SriLankan Airlines, knowing how many hours before your flight you can check in is important for a smooth airport experience. SriLankan Airlines allows passengers to check in online starting 48 hours before the scheduled departure time, and this service remains open until 2 hours before the flight departs. Online check-in can be completed through the SriLankan Airlines official website or mobile app and allows passengers to select their seats, confirm details, and download or email their boarding passes. For travelers flying with carry-on luggage only, this process can help save time by bypassing the airport check-in queue. Passengers with checked baggage can still benefit from online check-in by using the baggage drop counters at the airport, which open along with regular check-in counters. For those who prefer or need to check in at the airport, SriLankan Airlines’ airport check-in counters typically open 3 hours before the scheduled departure time for international flights and close 1 hour before departure. It is strongly recommended that passengers arrive at the airport at least 3 hours early for international flights to complete check-in, baggage handling, immigration, and security procedures without stress. For regional and domestic flights, passengers should aim to arrive 2 hours before departure, though specific times may vary depending on the airport and destination. Major hubs like Bandaranaike International Airport in Colombo (CMB) follow these check-in timings strictly, and late arrivals may result in denied boarding if passengers miss the cut-off. Boarding gates typically close 20 to 30 minutes before flight time, so early arrival ensures smoother processing and less time pressure. For travelers flying in Business Class, or those who are FlySmiLes Platinum or Gold members, SriLankan Airlines offers priority check-in services, which reduce wait times and allow faster movement through the airport. Families traveling with infants, passengers requiring special assistance, or those with oversized baggage are encouraged to arrive earlier than the standard check-in opening to ensure proper service and coordination. For flights operated under codeshare agreements, the check-in rules of the operating airline may apply, so passengers should always verify check-in times in advance. In select airports, self-check-in kiosks may also be available to speed up the process. SriLankan Airlines emphasizes the importance of checking in early to avoid delays caused by long queues or unexpected document verification. Whether you are flying to Asia, the Middle East, Europe, or Australia, following the airline’s check-in guidelines ensures that you have sufficient time to navigate all pre-flight requirements. In conclusion, you can check in for SriLankan Airlines flights online from 48 hours to 2 hours before departure, or at the airport 3 hours before international flights. Arriving early not only guarantees compliance with airline policies but also contributes to a relaxed and timely start to your journey with SriLankan Airlines.
