For Lufthansa flights, passengers can check in as early as 23 hours before the scheduled departure time. This early check-in window applies to most flights and allows travelers to confirm their travel details, select or change seats, and receive their boarding pass. Lufthansa offers multiple ways to check in, including online through its website, via the mobile app, or at airport kiosks and check-in counters. Online check-in is the most convenient option, enabling travelers to save time at the airport, especially those with hand luggage only. Once check-in is complete, passengers can download or print their boarding passes and proceed directly to security upon arrival at the airport. For those checking baggage, Lufthansa recommends arriving at the airport at least two hours before short-haul departures and three hours before long-haul flights to allow enough time for bag drop and security screening. At some airports, Lufthansa also provides late-night check-in services, allowing travelers to drop off their baggage the evening before their flight, starting from 23 hours before departure. Automated check-in is available for frequent flyers and registered users, who receive their boarding pass automatically via email or mobile message when the check-in window opens. For passengers who prefer checking in at the airport, kiosks and staffed counters generally open about two to three hours before the flight and close between 45 and 60 minutes before departure, depending on the route and airport. It’s important to be aware of the check-in deadlines, as failure to check in or drop baggage before closing times may result in denied boarding. Travelers flying from certain smaller airports may not have access to online check-in and must check in at the airport. Passengers requiring special services, such as assistance or traveling with large or non-standard baggage, are also advised to check in at the airport counters to ensure all needs are met. By checking in early, passengers have a better chance of selecting preferred seats and avoiding last-minute delays. Early check-in also helps identify any issues with travel documents or flight status, allowing travelers to resolve them in advance. Although most check-in methods open 23 hours before departure, passengers should always verify the check-in availability and closing times for their specific route and departure airport. In general, checking in as soon as the 23-hour window opens provides the greatest flexibility and convenience. For international flights, travelers should also ensure that passport and visa details are correctly entered during check-in to avoid delays at the airport. By planning ahead and using early check-in options, passengers can experience a smoother journey with Lufthansa and reduce stress on the day of travel. Whether using a mobile device, computer, or airport kiosk, completing check-in at the earliest opportunity helps ensure enough time for boarding procedures and a more comfortable overall travel experience.
