I guarantee Sun Express and Correndon wont be there in same shape in a few seasons
We must consider that pre-pandemic, Thomas Cook Airlines represented a huge amount of capacity between UK airports and Turkey / Greece for the leisure market. They didn't do much to Spain. If those countries want to attract UK tourists in similar numbers going forward, someone has to backfill that lost volume of airseats. The Turkish carriers have taken on that challenge. With Thomas Cook gone, there is a gap for them to fill. TUI and Jet2 can only do so much. They don't need to reinvent the market. Just pick up some of those customers displaced by the loss of Thomas Cook Airlines.
