Terminal 3 hosts 54 airlines across 3 gates.
DB tracks 4–7 sit under what FRA regulars call “Terminal 3”
At Frankfurt Airport, “Terminal 3” often means The Squaire complex above the long‑distance rail station, not a gate area with aircraft. The airport’s active passenger terminals are still coded 1, 2, and 3, but this building works more like a rail‑air hub and office block. If your boarding pass shows one of the 3 gates technically assigned to Terminal 3, you still check in and clear security through the main airport, not inside The Squaire itself.
Hilton and Sheraton sit inside The Squaire, not next to runways
The Hilton Frankfurt Airport occupies several mid‑level floors in The Squaire, literally above the tracks and below office levels, while the Sheraton Frankfurt Airport is attached on the Terminal 1 side. FlyerTalk regulars book these two hotels when they have 06:00–08:00 departures out of Terminal 1 or late DB arrivals after 22:00, because you can walk indoors in under 10 minutes to the main terminal check‑in rows.
DB long‑distance platforms run below; station hall sits on top
Long‑distance trains roll into platforms 4–7 under the complex, with elevators and escalators taking you straight up several levels into The Squaire’s station hall. That upper level holds the DB ticket area, the DB Lounge, and a small cluster of shops and eateries, so rail‑air passengers often use it as a landside waiting zone before walking over to Terminal 1 or taking the SkyLine train toward Terminal 2 and the future Terminal 3 gate area.
DB Lounge above the tracks doubles as pre‑flight office space
The DB Lounge inside The Squaire sits one level above the long‑distance platforms and is open to 1st‑class train tickets and certain BahnComfort statuses. Regulars with a 2–3 hour buffer before flights on airlines like Lufthansa, British Airways, or Emirates often park there with a laptop, then walk the few hundred meters to Terminal 1 or the SkyLine in about 8–12 minutes when it’s time to check in.
The gate‑side Terminal 3 project is still ramping up
Frankfurt’s actual Terminal 3 gate complex, planned to handle carriers such as Emirates, Qatar Airways, American Airlines, and British Airways, is separate from The Squaire and sits to the south of the existing runways. Current plans call for more than 20 contact stands, but for now you won’t find regular departures there; flights for those airlines still use Terminals 1 and 2 until the new facilities and their three initial gate piers are phased into operation.
Move between The Squaire and flight check‑in in one straight shot
From the DB platforms in The Squaire, you follow overhead signs for “Flughafen Terminal 1” along a covered passage that runs roughly 300–400 meters. Most travelers walk it in 6–8 minutes with a roll‑aboard, then hit the Terminal 1 departure level and standard security lanes. Build a 45‑minute buffer from train arrival to gate for Schengen flights, and at least 60–75 minutes for non‑Schengen departures that might leave from the Z or B concourses.
Practical tip: badge your rail ticket before heading for security
If you’re using a Rail & Fly or flexible DB ticket, validate or screenshot the barcode on the platform level in The Squaire before walking toward Terminal 1, because mobile signal can drop in some of the connector corridors. That way, if airline check‑in agents ask to see the train leg for through‑ticketed itineraries involving carriers like Air France, KLM, or SAS, you have it ready and don’t lose 10–15 minutes hunting for Wi‑Fi near the counters.
