In fact I used this service two weeks ago on the A319. Nothing to get overly excited about. The flight time was around 5 hours...reasonable load around 80% I should think. Curtailed IFE - but at least it worked unlike other AC flights I have endured recently. Don't know why they bother with the half a filled roll for "dinner". Seriously one half filled roll!!! Pathetic...better with nothing....having said that the breakfast served up around an hour before wheels down LHR was ok. The cabin crew all appeared to have an attitude that they wished they were somewhere else.
