I heard that Icelandair charges for all inflight drinks except for water, even during mealtime. This was confirmed by a couple of posting on airlinemeals.net as well as at the Icelandair website that says that a premium is charged for all drinks.
But, I also recently heard from a friend who flew them LHR-KEF in January that they were no longer charging for such services.
Anybody know the situation? I imagine that Icelandair's new service to SFO-KEF, a total of 8hrs and 30 min., would be hard going without any free drinks service.
