Passenger numbers rose 9% over a year at Luxembourg Airport, reaching 4.4 million in 2019.
According to figures published by the airport operator, July was the busiest month with more than 430,000 passengers.
Lux Airport said the growth was partly down to the addition of new connections to Budapest, Edinburgh, Menorca, Marsa Alam, Marseille, Split, Stockholm and Toulouse.
In 2019, airlines operating out of Findel served 89 destinations in Europe and the Middle East. The airport operator, meanwhile, developed new activities in the form of a nail bar and a click and collect service for duty free purchases via www.aeliadutyfree.lu
