Hi All
Liquid restrictions are due to come into force on 1st January 2010. They may, or may not do, as all summer they have been altering the date of introduction & finally postponed it to this latest date.
When it does come into force though you should still be able to take your drinks & snacks through the security at the entrance & into Departures
-it is just at the Gate security where liquids will be stopped & any you wish to carry on board should be in bottles of 100ml or less in clear, resealable plastic bags.
This is the information which ATM gave to Tour Operators at the start of 2009 season, so unless they have changed their mind you will still be able to take your own food & drink into the airport-thank goodness!
