I would have to agree with Kube. Although I don't travel frequently with AC when I do it is in business class. The standard of service in both the lounges and in the air are far from satisfactory. Recently I have encountered rude and unhelpful staff in LHR and YHZ and in the air even a simple request for a drink of water can bring an exaspirated look from the cabin crew member. Thank goodness most of my other trips are with Singapore Airlines: now they really do know how to look after their customers.
