Karen, Dalaman is not closed its open to all international/Domestic filghts, what has happened is that onuair has withdrawn there service, and the operator Aegean/holidays4you has now contracted/charter Pegasus to operate the service, but due to operational problems ie planes being in the wrong place at the wrong time, and obtaining air traffic control permission, flight plans plus time slots etc, the times and dates have been moved, therefore the reason for the offer of get a full refund or accept the change, which what you have chosen the change, are you outbound to bodrum and outbound from dalaman this is what we are doing, so its only a one way coach transfer a pain in the neck but we are going, would not miss calis at christmas and the new year, if we were staying in england we would plonk ourselves in front of the box and watch 600 hours of repeats and stuff ourselves silly.
Hope you make it to calis, and have a great time you never know we might even see you there.
Chris
