Easyjet will launch flights from Luton to Zadar in Croatia and the Isle of Man this year.
Flights to Zadar on the Dalmatian coast will start on March 27 while the new service to Isle of Man will launch on May 27.
The airline said that with the launch of the new service to the Isle of Man, its passenger numbers between the UK and the island would grow 6% year on year.
Easyjet already serves the Isle of Man from Gatwick, Liverpool and Bristol.
Across both new routes, the airline is expected to fly 29,000 passengers a year. It will operate twice a week to Zadar and three times a week to the Isle of Man.
Easyjet commercial manager Neil Slaven said:"We have seen increasing passenger numbers and demand year on year at London Luton Airport. We will continue to invest and develop Luton as an important London airport for both business and leisure travellers."
