Alamo is one of the few rental services even open past 11 PM, which is important when flying into Pittsburgh from the west coast. Overall the prices and service were very good but the airport check-in service was painful. There were two clerks occupied chatting away with customers about their travel plans, favorite restaurants, children, grandchildren, favorite teams. Those of us in line were forced to wait at least 10-15 extra minutes just to sign our forms. Worse, nobody mentioned the construction and detours between the airport and downtown Pittsburgh which were poorly marked and extremely confusing.
