Tui also have a slight advantage in that the European side of things is operating at a higher percentage of its schedule than its UK counterpart and has been for some time. The UK gov have done a grand job of "allowing" travel yet making it perilous to do so.
Id agree with pamann, no point in operating a full schedule if the planes are going a quarter full. Batten down the hatches and hope 22 is more back to normal.
