Hi wildrose. I also think you only need to arrive an hour before boarding since you only have hand-luggage. However, as it is an earlyish flight and I don't know how long your journey to the airport is, you probably will be awake half the night worrying, so may as well get there in good time. Don't know what the shopping is like there but I'm sure you could pick up a paper or anything from Boots (if there is one) to pass any spare time. One tip regarding bottled water is to take an empty water bottle to fill at your destination, and ask for water on board. Every airline I've used will give out free water in a cup, even Easyjet & Ryanair! Have a good trip x
