Tigs 2
To answer your original question.
I flew with TG LHR-BKK-LHR a few weeks ago in economy. No shoratge of wine - in fact they brought it round after the trolley service for those who wanted it.
No free adverts for Etihad from me. I thought the TG flight was excellent - plenty of legroom, good service - as pleasant as 12 hrs can be in Y in a 747.
