Luxembourg Airport will reach full capacity within the next three decades, according to the Minister of Mobility and Public Works Yuriko Backes, though the government is not yet considering relocation plans.

Minister of Mobility and Public Works Yuriko Backes explained that the current site is structurally limited and physically unable to expand, noting that a second runway will never be possible. In response to a parliamentary question from September concerning the airport's long-term future, she stated that while the government is examining all options to optimise current operations, international studies suggest these efforts will reach their limits between the 2050s and 2060s. She emphasised that early planning is crucial so that the country is not "caught off guard" once capacity runs out.

In a follow-up parliamentary reply to MP Meris Sehovic of The Greens (déi Gréng), Backes clarified that no site analysis has yet been planned, as the current priority remains modernising and adapting Luxembourg Airport within the framework of the coalition agreement. She added that any future search for a potential new location must be carried out carefully and based on rigorous criteria, given the scale and complexity of such a project.

The relocation process would therefore involve extensive administrative procedures and public consultations before any decisions are made.

For now, Luxembourg Airport still has roughly thirty years of operational life ahead. Development is ongoing: since spring 2025, the airport has been connected to the tram network, and Lux-Airport is working on repairing runway damage.

Alongside a new control tower, an expanded terminal is also planned to handle the airport's rapidly increasing traffic, as passenger numbers have nearly doubled over the past decade, from 2.69 million in 2015 to more than 5 million in 2024.

By 2032, a total of €1 billion will have been invested in the airport's development: €800 million from Lux-Airport and €200 million from the State.
