El Al canceled a planned flight route between Tel Aviv and Hanoi, Vietnam's capital, after it couldn't obtain security approval from the Shin Bet (Israeli Security Agency), the airline announced on Thursday.
According to the airline, it sought permission from Israel's security establishment to operate the flights but was told that it was not possible to grant the airline the permits necessary to fly the route using Israeli crew and planes.
El Al apologized to customers, offering to reimburse canceled flights with replacement flights to other locations, connecting flights to Hanoi with alternate airlines, or full refunds in the form of cash or vouchers.
The route was scheduled to launch in October.
