My last visit thro Munich ( T2)was in July, OK for arrivals as autoglide says. However, departure was another story. There were no effective queue controls on the outbound passport control desks & it took me in the region of 40-45 minutes to get thro. I was early so OK, several others missed their flights causing further queues at the LH service counters. At least in the UK we don't have exit controls ( yet).
I can think of many places a lot worse than MAN. Truth is, it's a lottery, some days good, some days crap, and that applies anywhere you go I'm afraid.
