If you're like me, the three letter city codes our industry uses for airports are confusing. I'm in the air flying from RSW , in a few months we'll open IAD, getting from SMF to SDF is difficult. Is Birmingham BHM or BMH? How in the world do you come up with MCI for the airport in Kansas City (better yet, how is Kansas City in Missouri?) Come on, those of us who live by intuition can never get where we're going by ourselves. MAF , MCO, BDL, and SNA ? I think it is all a bunch of CRP if you ask me. Thank goodness it is DAL or I would never get home.
Oh, by the way, Southwest used to have its own two-letter city codes. Think the three letter ones are confusing? I can't remember the codes off the top of my head but I bet there's a few of you out there that do.
