Firecat, here's a bit of info for you:
We live near Wetherby and went from Manchester this year for £303 with 20kgs of baggage. Its 80 miles each way to Manchester. Evening flight out and 3am leaving Dalaman on the way back
Have just booked Jet 2 from Leeds Bradford for 2010 - 15 miles away, so taxi is cheaper than car parking - and paid around £350 each; 22kgs of baggage, 10kgs of hand, on-line check-in and the flights are really sociable (16.00hrs take off out of Leeds and 21.30hrs take off from Dalaman back). Because Jet 2 fly Fridays and Mondays, we were able to do our "18 Day" holiday again.
Mancchester is dearer (some dates) than Leeds at the moment with Jet 2; they also fly from Newcastle. I think of all the "low cost" carriers, Jet 2 are Ok in my book, having flown with them loads of times. They are not the cheapest, but they are OK. And they have quite a few planes and growing.
We could have booked just now for around £275 each, for exactly the same dates, out of Manchester (Onur) and only paid a deposit now, with the balance end of April. That was attractive, but with unsociable flight times (check-in at Dalaman to come back at 6.00am?) and the drive from Manchester, I paid the extra for the comfort.
We fly out July 16th (23rd was the same price) all the dates after were significantly more. After we booked BMI in February this year, we noticed Jet 2 was well over £400 each - and its heading that way already with them for next year.
A bit of info for you, anyway.
cheers
