There are some good flight prices at the moment to Dalaman from Gatwick. If you are able to be flexible, and possibly fly with 2 different airlines, there are some good deals - some even Saturday to Saturday which has been unusual in recent years. http://www.skyscanner.net is a good website to use, if you enter the departure and destination then use the calendars to select a month, tick 'whole month' at the bottom - and you get a graph view which shows instantly the cheapest days to go. With the problems with the pound and the euro, this makes Turkey an even more attractive choice this year.
