Transiting through Frankfurt Airport (FRA) is fully allowed and is, in fact, one of the most common activities at this major European hub. As a primary gateway for Lufthansa and the Star Alliance, the airport is specifically designed to handle high volumes of connecting passengers. If you are arriving from a non-Schengen country and departing to another non-Schengen country, you can typically stay within the international transit zone without clearing customs or immigration. However, if your connection involves a flight to a Schengen area country, you will be required to pass through passport control. In 2026, it is important to check if you require an Airport Transit Visa (ATV) based on your nationality, as some citizens must have this document even if they do not leave the terminal. For long layovers, the airport offers excellent amenities, including nap zones, showers, and even transit hotels like the MY CLOUD Transit Hotel located directly within Terminal 1, Gate Z. Always ensure your bags are checked through to your final destination to avoid the need to exit the secure area to reclaim and re-check luggage.
