My may tc flights have gone up over 50% since we booked them. The flights I had with J2 for august had gone down a little from booking, but still, all are much much more than 2 years ago. I think I did 3 trips then for the price of one this year. I know it's market driven and all that, but when you can get 2 return flights to Barcelona for £140 all in, it's a bit of a chore to be forking out nearly £500 EACH for Dalaman!
Tip I had from a friend - if you want to take the risk of last minute booking, book any holiday that flies into
Dalaman on one of the cheapy last minute sites, just to get the flights cheaper, then book your transfers and accom for Icmeler. I've not tried it yet, don't know why I didn't think of it before!
