Personally I am not surprised to read this article which suggests airlines charge a huge mark up on food and drink. The article claims that drinking water on the budget airline Ryanair is 12 times more expensive than if you were to purchase it in a supermarket. In many ways it makes good business sense for the airlines, particularly with the current liquids ban. I wonder how many people have thought they have stocked up on water for the journey, usually seduced by the two for one offers before checking in, only to find that it can’t be taken through security. Whilst there doesn’t seem, to be a way around this, packing a sandwich seems a better plan that paying too much for airline food which is often poor quality for the price anyway.
