For Lufthansa flights, passengers can check in as early as 23 hours before the scheduled departure time. This applies whether you are flying domestically within Germany, across Europe, or on long-haul international routes. Lufthansa allows passengers to check in online through its official website or mobile app, making the process convenient and accessible from almost anywhere. Early check-in helps travelers save time at the airport, especially if they are only carrying hand luggage, since they can proceed directly to the security checkpoint and then to their gate. During online check-in, you can choose your seat, receive your boarding pass electronically, and enter passport information if required for international travel. If you prefer to have a printed boarding pass, you can print it at home or at a check-in kiosk at the airport.

Checking in early is recommended, particularly during busy travel periods, to secure a preferred seat and ensure smooth travel arrangements. For travelers checking in bags, Lufthansa advises arriving at the airport well in advance—typically at least two hours before departure for short-haul flights and about three hours before departure for long-haul flights. This gives enough time to drop off baggage at the check-in counter or self-service baggage drop and go through security without feeling rushed. Even though check-in opens 23 hours in advance, passengers still need to be aware of the closing time for check-in and baggage drop, which can vary depending on the airport and destination. For example, check-in usually closes 45 minutes before departure for short-haul flights and up to 60 minutes before departure for long-haul flights.

Lufthansa also offers automated check-in for certain passengers who frequently travel with the airline. If you are a Lufthansa Miles & More member or have booked a flight and provided your contact details, you may be automatically checked in and receive your boarding pass via email or text message 23 hours before departure. This service adds another layer of convenience, especially for travelers with regular itineraries. However, if you need to make changes to your seat or flight details, it’s important to manually check in and make adjustments before arriving at the airport.

In addition to online and mobile check-in, Lufthansa provides check-in options at airport counters and self-service kiosks. These options are helpful for passengers who prefer in-person assistance or those who need to check documents for international flights. If you're traveling with special baggage, such as sports equipment or musical instruments, or require special services like wheelchair assistance, it’s better to check in at the airport counter so the staff can ensure your needs are met.

In conclusion, Lufthansa allows passengers to check in up to 23 hours before their flight. Taking advantage of early check-in online or through the app allows you to select a seat, receive your boarding pass, and save time at the airport. Arriving early, especially when checking luggage or flying internationally, ensures a smoother travel experience and reduces the risk of delays or missed flights. Understanding these check-in options and times can help travelers prepare and enjoy a more relaxed journey with Lufthansa.
