Free 10-minute ride from LUX to Luxembourg City on Bus 6
Bus 6 is a regular city route from Luxembourg-Findel Airport to central stops like Hamilius in about 10 minutes, and the ride is completely free under Luxembourg’s national public transport policy. It runs as part of the AVL/RGTR network, so you just board at the airport stop and step off in town without tapping a card or buying any ticket.
The stop for Bus 6 sits outside the main terminal used by gates A and B, alongside the more heavily advertised airport lines 16 and 29, and that’s why many visitors miss it. Buses generally show “6” and the destination on the front, but signs inside the terminal tend to push people toward 16 and 29, so Bus 6 feels like the local option regulars use.
Timetabled frequency is roughly every 10–20 minutes in the daytime, but riders on r/Luxembourg mention that peak-hour traffic can add 5–10 minutes and sometimes causes bunching followed by gaps. After about 21:00–22:00, service on line 6 thins out further, so check the Mobiliteit.lu app before you walk out of the terminal to avoid standing at the stop longer than you need.
The big win is cost: a one-way taxi from LUX to the city centre often runs €35–€40, while Bus 6 costs $0 thanks to Luxembourg’s free buses, trams and 2nd-class trains. Regulars say to just board whatever comes first among 6, 16, or 29, then swap to a tram or another bus at Hamilius or Gare if your hotel is in Kirchberg, the station area, or elsewhere downtown.
How to use Bus 6 from Luxembourg Airport
- 1. Exit arrivals at LUX and follow the bus symbols toward the main curbside stop in front of the terminal serving gates A and B.
- 2. Check the digital display above the platforms to confirm the next departure for line 6, and note the destination and departure time shown in minutes.
- 3. Board through any door when Bus 6 arrives; you do not need to buy a ticket, validate a card, or interact with the driver for standard trips into Luxembourg City.
- 4. Ride about 10 minutes to Hamilius or continue to Gare if you need the main train station, keeping an eye on the interior screens that announce each stop by name.
- 5. Connect to other lines at Hamilius or Gare using the free tram (line T1) or additional buses if your hotel is a short walk from a different stop.
One last tip: install the Mobiliteit.lu app on airport Wi‑Fi before leaving the building so you can compare real-time arrivals for lines 6, 16, and 29 instead of waiting blindly at the stop.
