FA's stopping me in the MSP airport to see how I am doing and where I am off to this time..........the FA who brought me "my regular" drink without even asking what I would have...The Boston based FA who now keeps counts how many times we have flown together!
My favorite used to be when I was flying out of BGM (before moving to MSP) and the ground crew who would wave to me if they saw me looking out the window when they were marsalling the plane/bringing in the jet bridge.
Know its not NW but my favorite yet is when the TSA folks at the Skyway at MSP noticed I got new luggage and told me they liked the pattern on the old one better...
Gag my life is sad!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
