We had to change planes in Chicago. United gets points here for super close gate to our connecting flight to Frankfurt, Germany.
The flight was late, Group 1 and to were finally boarding, the announcement for our group - group 3 - to board never came, so we boarded after waiting around for a while.
Everyone seemed slightly confused about the boarding procedure.
Service during the flight was OK, nothing outstanding - especially compared to our flight back to the States from Germany with Lufthansa, everything from the service to the condition of the plane just was a notch below on United.
