At Frankfurt Airport (FRA) in 2026, moving between Terminal 1 and Terminal 2 is free and takes about 10 to 15 minutes using either the SkyLine train or the Shuttle Bus. The SkyLine train is the most efficient method; it runs every 2 to 3 minutes and has stops in both the public area and the transit (airside) zone. If you are landside, you can find the SkyLine station on Level 4 of Terminal 1 (near Pier B) and Level 3 of Terminal 2 (near Shopping Plaza). Alternatively, free yellow Shuttle Buses depart every 5 to 10 minutes from the curbside in front of both terminals. For 2026 travelers, the "pro-tip" is to use the SkyLine if you are connecting between flights without clearing customs, as it allows you to stay in the secure area. If you have heavy luggage and need to go to the Long-Distance Train Station (Fernbahnhof), the Shuttle Bus is often more convenient as it drops you closer to the Terminal 1 entrance near the rail link.
