I'd go charter everytime. Direct flights and much better seat pitch/IFE now. First Choice broke ranks a few years ago and their product is excellent.
Better seat pitch (33in) in economy than Emirates, BA etc and better IFE (you can start/stop films whenever you want). The scheduled carriers are having to do catch up.
First Choice Premium is even better and great value (36" pitch and free drinks etc).
Look at the cost difference, the flight times (allowing for transfers etc) and it's an easy choice.
Charters are not what they were, they are now setting the pace for mud/long haul as the LoCo's have taken over their traditional bucket & spade routes.
