If you're flying with Turkish Airlines, knowing when to check in is essential for a smooth travel experience. Turkish Airlines check-in options include online check-in, mobile check-in, airport counters, and self-service kiosks at select airports. The online check-in window opens 24 hours before your flight’s scheduled departure and closes 90 minutes prior to takeoff. You can check in online through the Turkish Airlines website or mobile app by entering your booking reference (PNR) or e-ticket number along with your surname. Once completed, you can select a seat, enter passport details for international flights, and download or email your boarding pass. This allows you to skip long lines at the airport, especially if you're only traveling with hand luggage. If you have checked baggage, you can still check in online, then drop your bags at the baggage drop counters, which usually open 2 to 3 hours before departure and close 60 minutes before international flights and 45 minutes before domestic flights.

For travelers who prefer to check in at the airport, Turkish Airlines airport check-in counters generally open 3 hours before international flights and 2 hours before domestic flights. These counters close 60 minutes before departure for international flights and 45 minutes before domestic flights. Turkish Airlines strongly recommends arriving at the airport at least 3 hours before international flights and 2 hours before domestic flights, especially during peak travel times. This allows enough time for baggage check, security clearance, passport control, and boarding procedures. At major airports like Istanbul Airport (IST), Ankara Esenboğa Airport, and Sabiha Gökçen Airport, you’ll also find self-service kiosks that let you check in, choose your seat, and print your boarding pass or luggage tag quickly.

Priority check-in counters are available for Business Class passengers, Miles&Smiles Elite and Elite Plus members, and those who have purchased premium services. These dedicated lanes help reduce waiting time and speed up the check-in process. For passengers traveling with special needs, infants, unaccompanied minors, or extra-large baggage, airport check-in is necessary, and arriving early is highly advised. If your journey includes a codeshare flight operated by another airline, check-in times may vary, so always confirm the correct process with the operating carrier.

Turkish Airlines may also request in-person check-in for certain visa-required destinations, where document checks are required before boarding. For international travel, ensure you carry a valid passport, visa (if applicable), and other required documents, as they will be checked during check-in or boarding.

In conclusion, you can check in for a Turkish Airlines flight as early as 24 hours before departure online, or at the airport starting 2 to 3 hours before flight time. Completing check-in early, especially online, ensures quicker processing and better seat options. Whether flying domestic or international, checking in on time helps you avoid delays and ensures a stress-free start to your journey with Turkish Airlines.
