Hey, cool - thanks for posting this thread. I'm actually flying home on NW 2243 MSP-SEA at 7:15 PM on the 31st - not quite the final NWA flight but close enough where I feel comfortable saying I was on one of the very last Northwest flights
If I recall correctly, it's sometimes traditional for airlines to allow employees to wear "classic" uniforms on occasions like this. I wonder if Delta will allow that as an option for NW employees on the last day of the NW certificate... would be a nice commemorative gesture I think.
