But why cancellations for Spain and Morocco? French airspace could have been avoided for these destinations ex UK, although flight timings would have been longer.
The usual way to get to Spain/Morocco without flying through French airspace would be to use oceanic airspace (Tango routes). This requires HF radio which only the EZY A320's are equipped with, not the A319's.
At some points the slot delays were up to 360 minutes long, making the flying programme unsustainable I would have thought.
