During a recent flight from the airport in Portland, Maine, I stopped to check the board that lists the arriving and departing flights. A gentleman in a purple vest surprised me, by asking if I needed any help. That was Henry, one of 7 "Ambassador" volunteers at the airport. The role of the Ambassadors is to make it easy for travelers to navigate their way through the airport, and arrive at their gates, stress-free.
