The 2L portion always seemed too convenient a coincidence for the IATA-obsessed airline world, conversely only a million possible combinations would seem shortsighted. But the chance that pre-internet fact being documented anywhere readily findable is nearly nil.

That said: I've just realized that my Ohio drivers' license number -- and I have no idea why this is residing in the quick-access part of my brain -- is also 2L6N... Now I wonder if there's some ancient database system where that was a default data type.

More than one agent has been confused when I've walked up to a kiosk and (quickly) punched in my MP# ("sir, that's not a confirmation number", "you need to scan any credit card") and had my reservation magically appear.
