I think a lot of the criticism of MAN is just your average Brit having a moan and saying how much better everything is everywhere else. We just love slagging our own places off at the expense of just about anywhere else.
The same people that huff and tutt in UK queues are generally the same people that laugh and joke in queues in HKG, SIN, etc etc
MAN has improved immeasurably over the last few years in all respects other than Border Control, it deserves considerable praise for the investments it has made in security areas and the like to alleviate some of the bottlenecks.
What it can't change overnight is the inadequate nature of both T1 and T3 but if rumoured demolition and rebuilding of both come to pass, we will end up with a short term pain for long term gain.
Given a) the high seasonality of the airport and b) the peaks and troughs as the large based fleets depart and return, it's a wonder it functions at all.
Just out of interest - extrapolating the peak morning summer flows into an annual norm..........what passenger number would that produce on an annual basis?
