EasyJet is expanding its network from Luton airport to 59 destinations with three new routes.
Flights to Nantes, Marseille and Valencia start in February with one-way fares ranging between £28.49 and £34.49.
The budget airline expects to carry 133,000 passengers a year across the three services, which will operate four times a week to Nantes and Marseille, and three times a week to Valencia.
EasyJet is expected to fly more than six million passengers from Luton airport this year, an increase of 500,000 over the last 12 months.
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. The three new routes on sale today further bolster our summer destination on offer to customers in the region.”
