Aloha from Spain. Made the flight and it wasn't actually that bad. Luckily for me I was flying from East Mids with Ryanair in the afternoon. I turned up 2 hours before the take off and only had to queue for about 15 minutes. The Easyjet queue was pretty huge and BMI had cancelled most of their flights.
I couldn't take anything on as hand luggage except my passport, a few printed e-mails including my travel arrangements and my wallet. They wouldn't allow sweets or my book!
The security involved a proper bad down, the usual metal detection and x-ray check of everything including all my hand luggage and my shoes.
Once through to departures it was all as you usually expect even had the electrics shop open (why? it's not like you can take it with you!).
The flight took off on time and was pretty boring without an ipod or a book to read. Landed 5 minutes ahead of schedule as well.
The baggage throwers were true to there name and I saw the bags be unloaded from the fly. Well, I say unloaded, it what actually happened is someone dropped the suitcase from about 2 foot onto the conveyor belt. Luckily for me it seems how high they dropped it from depended on the weight. The heavy ones got thrown but the light ones just got a small drop. Thankfully mine was reasonabily light and didn't get the full treatment.
Checked my 20D and it's all good. I packed it in a small Lowepro bag I have inside my luggage so it had some good padded protection. My 100-400 L IS appears fine but will test it fully later today. I put it in it's L case packed with bubblewrap and then wrapped it in clothes.
All in all it went a lot better than expected.
