Luxembourg Airport has handled nearly 2.5 million passengers in 2014, marking an increase of 12.3% when compared with the same period in 2013.
The airport handled around 270,000 additional passengers in one year.
The rise was driven by Luxair which opened three new destinations, including Dublin, Stockholm and Lisbon, increased frequencies on several other routes such as Milan, London, Copenhagen and Porto, as well as developing competitive prices.
The airport said that easyJet has also significantly contributed to this rise, by launching a new service to Lisbon at the end of 2013 in addition to London and Milan.
Turkish Airlines, which started flying to Luxembourg in 2013, has almost tripled its traffic through additional frequencies that now allow connection to everyday Istanbul and the rest of the world.
The increase in passenger traffic is contributed by nearly all 11 airlines operating in Luxembourg.
According to the figures released by the airport, movements increased by only 3%, confirming the trend to use larger capacity aircraft and improved load factors.
The airport anticipates to handle close to 2.7 million passengers this year, up by 8%.
Luxair is expected to increase aircraft size to Rome, Nice, Madrid, Munich and Barcelona, as well as offering additional frequencies to London City, Hamburg, Stockholm and Dublin.
Turkish Airlines will also increase the capacity of its aircraft by using more Boeing 737-800 with 151 seats.
Besides the existing airlines in Luxembourg Airport, Sun Express will also begin offering flights to the Turkish Riviera, in addition to those of Luxair Tours.
