There are lots of great deals in june from various airports to Dalaman with Fly24.co.uk some of the deals are from Gatwick on Pegasus flights via istanbul with a stopover/ change flight of 90 mins for as little as £158 33p return with 15 kg bags on 13 june for 14 nights quite good flight times as well..
other deals are direct to dalaman out with one airline back with another airline prices are cheaper than booking direct with the airlines .
Beware though this is a German based travel agent who appear on Turkish airlines web flight info they are not ATOL or bonded as far as i can see but pay by card should be ok
