Wizz Air will become the latest low-cost carrier to operate from London Southend when it launches two routes later this year.
The Hungarian airline will fly to the Lithuanian capital Vilnius and the Romanian capital Bucharest.
Bucharest will run Monday, Wednesday, Thursday, Friday and Sunday from November 22, and Vilnius will run Tuesday and Saturday from November 23, both operated by Airbus A320s.
The airline also announced new daily flights from London Luton to Vienna from July 1, 2020 and twice-weekly flights from Luton to Castellón from December 13, 2019.
London Southend, to the east of the capital, is primarily used by fellow low-cost carriers Easyjet and Ryanair, as well as regional carriers Flybe and Loganair. Air Malta and Volotea run seasonal routes.
It is accessible from London via a 50-minute train from Liverpool Street or a 45-minute train from Stratford.
Airport operator Stobart Group has signed a five-year partnership with Wizz.
It wants the airport to handle five million annual passengers by 2023, and says it wants the new routes to bring in 250,000 passengers in the first year.
Wizz Air is a fast-growing presence in the UK market, recently overtaking Easyjet as the largest carrier at Luton.
Owain Jones, Managing Director, Wizz Air UK said: “It is exciting to see Wizz Air painting the skies pink at Southend, as we expand our footprint across the Greater London airports.
“The new routes from Southend and London Luton demonstrate that Wizz Air is committed to offering customers ultra-low fares to destinations across all of Europe, connecting the UK with cultural hubs and off-the-beaten track destinations.
“Whether it’s a family holiday, trip of a lifetime or a quick weekend escape, Bucharest, Vilnius, Castellón and Vienna have something for everyone to enjoy. The Wizz team looks forward to welcoming customers old and new on-board our ultra-efficient fleet of Airbus aircraft very soon.”
Flag carrier LOT Polish Airlines launched flights from London City Airport to Vilnius in May.
