The two times that I thought there were FAMs on a flight, the suspected FMAs were not wearing suits.

The first was a Delta ATL-MIA flight in February 2005. I boarded first, but there were two people sitting in the center seats in the last row of F (a 767), wearing short sleeve polo shirts and khakis.

The second was in February of this year on a AA ORD-LGA 757 flight. Two young guys dressed in "hipster" stlye clothes boarded ahead of everyone else and took aisle seats in Rows 2 and 3.

But for their attire, I would have had no doubt that they were FAMs.
