Reading the codes I tend to convert them to their city-name, like Tampa for TPA and Orlando for MCO. But when typing them I'll be saying to myself "I need to fly from T-P-A to C-D-G."

Which brings up the two-airports one-city phenomena and how my brain interprets it. CDG is "Charles de Gaul" and ORY is "Orly" right away in my head, and while i frequently use PAR to search for both, it's not Paris, it's "Par" as in "Par for the course."

So, I've definitely searched and typed and thought "Tampa to Par" more then once.

MSP to me has always been "Minneapolis St. Paul." and I'm not even sure if that's even right.

And odd note - SNA is "John Wayne" (not "Orange County") and the alternate airport for that route for me is often SAN, which is read by me as "S-A-N *pause* Diego" as if the SAN triggers the "Diego" immediately in my mind.

And the problematic route i've been trying to hash out as an open jaw recently: "TPA-PAR, VCE-TPA" which is "Tampa to Par then Marco Polo to Tampa." Which brings up routings with stops in IAH or EWR frequently - making me question "Do I want to stop at George Bush and get the extra miles or go via Newark?" and sometimes I call HOU just "Continental" or "Intercontinental."

As for Chicago, ORD as "Ordh" is a place and MDW as "Midway" is a place but i've never said "I'm flying to Chicago" and the idea of a "Chicago Airport" is totally foreign to me.
