http://www.terminalu.com/travel-new...e-compared-to-supermarkets-study-shows/12109/ We all know that airline food on budget airlines costs more than the supermarket equivalents, but a new survey suggests that it is more than most people might expect. A UK study by travelsupermarket.com said a family of four can easily spend £45 for a sandwich, drink and crisps on an airline each way, following its comparison of supermarket, airport and onboard prices. Europe’s biggest carrier Ryanair,was singled out in the research for charging more for many in-flight food and drink items than any other British or Irish airline. The airline charges £3 for a 500ml bottle of water – 12 times the price of an equivalent water, which is 25p a bottle when bought in a six pack at the supermarket. The study found some of the highest onboard mark-ups among the budget carriers were on hot drinks, including tea and coffee. Ryanair charges £3 for a cup of tea – almost double the best available price at an airport, or about 20 times the cost of making it yourself using tea bags bought from a supermarket, costing about 15p each.
