To check in with LOT Polish Airlines, passengers can choose from online check-in, mobile check-in, airport counters, or self-service kiosks. Online check-in is available starting 36 hours before departure and closes 120 minutes before long-haul international flights and 60 minutes before short-haul flights. Travelers can check in by visiting the LOT website or using the LOT mobile app, where they can enter their booking reference or ticket number, select seats, and download their boarding pass. This method is fast and recommended for passengers traveling with hand baggage only, though those with checked bags can still use online check-in and proceed to the bag-drop counter at the airport. Mobile check-in through the LOT app offers the same features and stores the boarding pass digitally, allowing quick access at security and the gate. For passengers preferring the airport, LOT provides check-in counters that open 2 hours before European flights and 3 hours before intercontinental flights, closing 60 minutes before departure for long-haul and 30 to 45 minutes prior for short-haul depending on the airport. At major hubs such as Warsaw Chopin Airport, LOT offers self-service kiosks where passengers can check in, select seats, print boarding passes, and print baggage tags before dropping luggage at dedicated counters. Passengers in Business Class or with Miles & More status have access to priority check-in counters for faster processing. To avoid delays, LOT recommends arriving at the airport at least 2 hours before short-haul flights and 3 hours before long-haul departures, even when using online or mobile check-in. Boarding usually starts 45 minutes before departure, and gates close 15 to 20 minutes prior to takeoff, so being punctual is critical. For certain destinations, especially in the U.S., Canada, and Israel, additional security screening may apply, requiring earlier arrival and possibly limiting online check-in availability. In such cases, check-in must be completed at the airport, and LOT staff will provide assistance. Regardless of the method, passengers should ensure they have a valid travel document, visa (if required), and COVID-related paperwork (if applicable), as LOT may deny boarding if documents are missing or invalid. Special services such as unaccompanied minor travel, passengers needing mobility assistance, or those traveling with pets must check in directly at the airport. In summary, LOT Polish Airlines offers flexible check-in options: online from 36 hours in advance, mobile via app, airport counters, and self-service kiosks. Each method is free, easy to use, and tailored to various passenger needs. Checking in early helps secure better seat selection, speeds up the airport process, and ensures travelers meet all documentation and baggage requirements. LOT’s multi-channel check-in system improves efficiency and allows passengers to begin their journey smoothly, whether flying within Europe or on long-haul international routes. Using the online or mobile tools when possible is the most convenient way to complete check-in, and LOT encourages all travelers to take advantage of these services to avoid queues and last-minute stress
