Yes, you can walk between many of the terminals at Frankfurt Airport (FRA), but the ease and time required depend on which terminals you are connecting between.
Frankfurt Airport has two main passenger terminals: Terminal 1 and Terminal 2, which are further divided into concourses.
Here’s a breakdown of how walking works:
Terminal 1 is the larger, older terminal shaped like a “U.” It has three concourses: Concourse A (Gates A1-A59, Z1-Z12) Concourse B (Gates B1-B65) Concourse C (Gates C1-C23)
You can walk between Concourses A, B, and C entirely airside (after security) without needing a shuttle or train. It involves walking through corridors, which can take 15-25 minutes from one end to the other (e.g., from Gate A59 to Gate C23). Moving walkways are available in some sections.
Terminal 2 is smaller and has two concourses: Concourse D (Gates D1-D24) Concourse E (Gates E1-E26)
You can walk between Concourses D and E airside. They are connected via a central building, and the walk is relatively short (5-10 minutes).
This is where it changes. The two terminals are separate buildings about 1 km apart. Landside (before security): You can walk
