In 2026, the length of time you can stay in transit at a German airport (like Frankfurt or Munich) depends on whether you remain in the International Transit Area (Airside) or pass through immigration. If you stay airside—meaning you do not enter the Schengen Area—you can generally remain in transit for a maximum of 24 hours, provided your layover is within the same calendar day or overnight at a hub that supports 24-hour transit. Most German airports do not allow passengers to stay airside overnight if the transit area closes, which can happen at smaller airports like Berlin or Hamburg; in such cases, you would be forced to enter the country and would require a visa if your nationality demands one. For Indian nationals, a major policy change in early 2026 has significantly simplified this: the requirement for an Airport Transit Visa (ATV) is being lifted for those staying airside, making it much easier to connect through Germany to the US or Canada. However, if your transit requires you to switch terminals that are not connected airside, or if you wish to stay in a landside hotel, you will need a full Schengen visa.
