Not sure it is a rare as you may think.
I have just got off easyJet from Palma. The 10:45 easyJet was cancelled
there are no seats on ba / Ryanair / easyJet until Wednesday.
the best was veuling indirect at some e600
the flights are sold out for days so when easyJet cancelled it this morning they will know they have now got 200 pax at the end of half term who will miss school etc.
the only way home is long and expensive.
