An extra day in February certainly helped, but the leap year alone does not solely explain the gateway's 27.7% upturn in traffic, its 23 consecutive month of passenger growth.
A total of 870,000 passengers passed through its facilities in February, which the airport puts fown to a fast expandig route network and the growing popularity of European city breaks.
The number of travellers flying to Copenhagen more than doubled in comparison with the same month last year, for example, while over 50% more passengers flew to Rome and a third more travelled to Zurich.
LLA is also quick to point out that travellers are benefiting from an ever-expanding choice of routes. This month alone will see the launch of six new services to Amsterdam and Barcelona (Vueling); Kaunas and Palanga (Wizz Air); Jersey (easyJet); and Turin (Blue Air).
Six further new routes have already been confirmed for the summer schedule, including two with new airline partners, Transavia who begin flights to Paris Orly and Adria Airways who will serve Pristina in Kosovo.
To meet demand, LLA is currently undergoing a £110m development project to increase annual capacity by 50% from 12 to 18 million passengers by 2020.
According to the airport, the project will deliver a complete redesign of the terminal to create a friendly and efficient passenger experience.
Key to the upgrade, says LLA, will be exciting new shopping and dining options, expanded security search, baggage reclaim and immigration facilities and major enhancements to transport links.
Nick Barton, CEO of LLA, enthuses: “LLA is continuing to grow at an astounding pace. The airport’s great range of destinations, with frequent flights that serve both business and leisure passengers, is central to our appeal.”
“Creating strong public transport connections is key in allowing us to meet the need for capacity expansion.
"That’s why we are delighted that Luton Borough Council has this week supported our vision to increase the number of fast trains serving the airport to four per hour, in line with the service levels enjoyed by other London airports.
“With a journey time of just 20 minutes between London St Pancras and Luton Airport Parkway, four fast trains an hour will more than double the number of passengers travelling to the airport by public transport.”
