Sorry to piggyback but not sure of a better thread.

United says to allot 3 hours for international departures, but Munich airport seems a bit smaller than others. When should I aim to check-in my bag for a 12:20 pm flight to the US on United this Sunday? Arrive say 9:30?

Also, looks like PP Lounges are only in terminal one, while my flight leaves from terminal 2, right?
