Flying Clara I'm assuming for your sake that you don't work for an airline (and lets hope if you do it's not easyjet).
I agree you can bring water, coke cola, orange juice on board the aircraft if you buy them airside or if they're brought through security empty. Ryanair has it's crew room airside and they are able to fill their containers up from water machines available to them. Unfortunately easyJet does not have crew rooms airside so this is not possible, also no water machines, so a little difficult to do this.
Stop biting Guys and gals!! FC is a wynd up merchant! We do not see it on the private page because it is not an employee.....simpoles!!!
Yes I know Rosco328 but it's so much fun to bite sometimes and she makes this thread so much more interesting to read. I read it to have a laugh at her comments!
