I fly to Frankfurt 2-3 times a year for work. It pisses me off that the US based carriers (United, American) line up their cattle in the main thoroughfare of the airport and block everyone trying to get to other gates. All the other gates and airlines seem to be able to board without lining everyone up like pre-kindergarteners.
