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!
