I used them 3 times this year.
I flew out of Gatwick to
Dalaman at New Year - all was fine, and again from Exeter to Dalaman in May and August - both times again absolutely fine.
There isn't any in-flight entertainment (except for altitude, speed etc on drop-down monitors) and the food's a not fantastic but is edible. There wasn't a bar service on any of my flights, though you could get wine or beer and all the soft drinks were free and plentiful - stick a couple of miniatures in your hand luggage if you like to start your holiday as you mean to go on...
Cigs were cheaper on board too - if you're willing to take the risk of being able to get the brand you smoke.
Actually I've probably made them sound awful - but they're fine.... really!
