Just to a bit of reverse psychology, if you prepare yourself for the worst, when you get there things can only be better. The main reason you will get congestion on the flights is that most airlines from the UK all travel on the same day, it's cheaper, and with all the fans pouring in the airport will be beyond capacity. Monday will be the busiest, especially up north.
Yes, Zante has been improved to provide cover when queuing out in the sunshine, Corfu is going to have a bottleneck at security not check-in where you now have to remove your liquids, take outer garments off, agree to random searches and shoe scanning, etc, etc, etc. There are only 2 machines and no room for any more. I'm flying more and more with work now and the airport experience is horrible and in my opinion overbearing, not wanting to offend anyone hear but if somebody was really determined to take an aircraft down they would manage it, I saw little wrong with our previous security measures. For anyone who is familiar with Manchester it now often takes 40minutes to 1 hour to get through security and that was before the summer season started, they are frantically putting extra scanners in so hopefully that will alleviate some.
Everton, Liverpool, pah! I support Manchester Untied - Champions!
