Sorry to hear of your woes but was your flight early and therefore
you had to wait for a position?
Come to think of it, this flight arrived at 06:33, as I looked at an arrival log that day. The schedule time of arrival is 07:10, so that accounts for 37 minutes of the wait, and then add on 5 mins of taxi time (as the EY had to wait between 05L/R, then there is your 42 minutes.
So, to summerise, not a MAN issue whatsoever!
I don't know, 'Wanna be There' if you work at MAN, but this is the attitude that drives me to despair of MAN. Typical MAN take or shove it response. No idea at all of customer service. Perhaps, from the airline and pax perspective, it didn't seem that big an issue to arrive half an hour early, it's not unusual after all. Perhaps they thought the airport actually might be able to accomodate them, it does after all like to tell everyone how great it is without actually delivering it. 40 odd minutes is unnaceptable, end of. But as you say, the flight arrived a bit early so it's not MAN's fault, it's the airline...how rude of them.
