Time will tell if Jet2 have made the correct call, and indeed I wouldn't be surprised to see others follow suit. What I don't get is why they needed to make that call at the start of April other than (as a previous poster mentioned) to send a message to the government. Say Portugal and Malta are on the green list, are you really not going to fly to those countries for over a month of the summer season just because Spain, Greece etc are not open - surely you maximise all opportunities to make money where you can? This is why I think other airlines are maybe holding fire for the time being, things can change a lot in a month. Also, with regards to TUI - they may end up cancelling all flights as Jet2 have done, but with Mexico, Dominican Republic, Barbados and to a lesser extent the US doing well, there's the opportunity to start a limited long haul programme alongside a few short haul destinations such as Morocco and Portugal.
