I flew Etihad from Bangkok to LHR earlier this year. Their aircraft are mostly very new, the food's good and so's the in flight entertainment system (the best i've seen). However Abu Dhabi airport is the pits (although they're opening a new terminal soon, I believe). I had a nasty experience as we touched down just before fog fell (a common problem there apparently) and spent a nasty 11 hours overnight in Abu Dhabi before we could continue. The fog of course I couldn't blame them for, but their terrible customer service (complete lack of information, and lots of empty promises) really put me off flying with them again.
