Israeli flag-carrier El Al is preparing to switch its London Stansted flights to London Luton from the beginning of May.
Reservation data from El Al's booking engine, as well as the Amadeus distribution system, shows that the airline will offer a non-stop Tel Aviv-Luton link from 3 May.
The airline could not immediately be reached to explain the decision.
El Al will operate the route with Boeing 767 aircraft, according to Amadeus, six times per week. The carrier also serves London Heathrow.
