I flew on G-JMAB to / from Dalaman from Manchester in September 2004. I think a 753 is regularly used on the friday Dalaman flight. Having said that, passenger numbers to Turkey are way down this year compared to recent years so don't quote me on it!

They usually fly to places such as AYT, DLM, REU, IBZ, etc. Not sure of which destinations on which days as i no longer work on the tcx contract, but i could find out for you when im next in work on friday where they go on each day.
They also fly to the canaries and some greek islands such as Kos. I was lucky enough to end up on one of their 757-300's last year for my flight to Ibiza and got G-JMAA outbound and G-JMAB inbound. Nice aircraft, a long walk to your if your seat if you're sat right at the back! Just hope you don't sit where the guy who pissed himself sat on our outbound flight!
