Thanks irishguy28 for your reply. I fear I may have covered up my real question in my original post - I was actually trying to find out whether being an EasyJet Plus member in the situation would have meant I was dealt with sooner and could have made my way away from what was turning into a very hostile situation (Ryanair were making their customers queue the full length of the airport and I think I counted 3 "lanes" of Ryanair passengers that stretched the length of the airport whilst EasyJet were only calling passengers forward if their flight was actually checking in/going to leave)
By 4pm on Sunday afternoon, there was a lot of jeering and whilst I can understand people's frustrations, it didn't make for a comfortable place to be, hence why I was looking to be out of there as soon as I could. As it turns out, most of the evening flights did eventually depart, albeit with some considerable delays. I reckon there will be a fair bit paid out in EU Compensation for those flights, but afraid that I don't qualify as my flight was cancelled due to "exceptional circumstances" - at least I can claim back my food and other expenses from the delay in getting home to Scotland!
