I have now fired off my 'complaints' or comments to Easyjet. In the process I also checked my rights and discovered that they had not complied with late-boarding rules.
At Paphos, once we got airside, we discovered that our flight had been delayed by 2 hr 35 min; in fcat it went off chocks 2 hr 50 min late.
There were no airport staff airside except for catering personnel. There was no Easyjet rep to explain our rights to free refreshments. The delay was due to crewing problems at Luton; the captain had had to be driven from Gatwick.
Clearly the delay was know for several hours but no attempt was made to inform or compensate passengers except for the delay message on the departures screen.
