More than 20 airlines are active in the airport these days and the numbers are expected to increase soon. There are still dozens of airlines that have not yet returned to Israel and it is not clear when they will return for sure.
Many airlines cancel the flights to Israel until a certain date, but from that date, they sell tickets, even though they have not definitely and definitively decided to return to Israel on that date. Wizz Air and Ryanair have also recently canceled quite a few flights to and from Israel following adjustments to the flight schedule and the reduction of operations.
