These are my choices for an upcoming TATL trip from the US to Italy -- would appreciate opinions as to whether the 90 minutes in MUC is cutting it too close for comfort. The flight has a fairly decent on-time performance record, and my sense is that the MUC airport is relatively small and navigable. My initial instinct was to go for the longer layover in FRA -- depsite the fact that it is FRA -- but now I think I am perhaps being too much of a nervous Nellie, and that 90 mins should be fine. The MUC flight opens up more booking options, which is another factor I need to weigh. Many thanks in advance for your .02.
