Food and drinks on the plane: One of the most important "features" of low cost flights is that the airlines do not offer free food and drinks on the plane. Food and drinks are sold on board, but they are quite expensive. If you travel on a low budget you should take some sandwiches from home. But remember that you cannot carry any liquids in your hand luggage past the security check!
