Until now Air Berlin has offered free hot meals on flights that take over four hours. According to the magazine "Travel One", this has stopped from 01/05/2009 on.
This affects also the flight route to Fuerteventura and to the other Canary Islands.
Air Berlin now only serves cold meals in the form of sandwiches. If you still prefer a hot meal you have to pay an extra charge. Here it makes sense to order it in advance. On short-distance flights within Germany, Air Berlin even describes the meals as "snack". Such a snack is probably even smaller than a sandwich.
Other airlines have adopted this approach for years and do not serve hot meals any longer.
We were not able to find out yet if these news are also applied to business class.
