Luxembourg Airport works for rural bases beyond the capital. For a city-only stay, compare public transport before reserving a parked vehicle.
The airport places rental counters on arrivals level -1 and rental cars in Indoor Parking A on level -2. Follow the specific operator’s return instructions and check any parking height limit for your chosen category.
A car is useful for a countryside circuit through the north, castles and villages. For Luxembourg City alone, compare public transport with a parked rental. Collecting after the city stay can reduce unused rental days.
Compare airport collection with a later collection if you start with a city stay. Include the transport to a different rental branch and any extra parking nights when comparing the total cost.
