ABBO :
Sounds like you had a rough time there. I agree with most of what you said.
It seems to me that the cabin crew were at fault for the following reasons :-
1) Not collecting any witness statements from passengers. (Without which, taking it further is effectively impossible.)
2) Not identifying the offenders to the police on arrival.
Try putting this in a letter to the airline, and ask for a refund. Tell them that if you don't get a full refund you will contact the CAA directly stating that the cabin crew were 'negligent' in their basic duties.
The words 'negligent' and 'CAA' will certainly get their attention, I can assure you !!! Good luck with that and let me know how you get on.
IMHO I do not think that the Captain and First Officer would have made the decision to land at Gatwick unless they were legally bound to do so, due to insufficient reserve fuel. It is more hassle for them to do that, as they then have to get transported by road to Manchester to get their cars and then drive home themselves.
Gatwick to Manchester 10 minutes by air ? (- Anyone done it recently / got times from overhead Gatwick ?)
Anyway at least we all know now that what we read in the press is similar to the Dandy.

I find it easier to create my lengthy reply's off line. Then "cut and paste" it into the "Replies" section afterwards, saving much thinking time, mistakes and surfing money.
