ORD, JFK, SFO, AXA...where do those

ORD, JFK, SFO, AXA...where do those airport codes come from anyway?.

Then there are the lousy and apparently random Canadian codes where most but not all start with Y. Lots of contradictory opinions here :: http://www.airlinequality.com/Interact/Q1_J00135.htm

Interestingly enough, American codes all start with K. The difference is, in Canada it looks like they don't drop the Y, whereas in America the K is ignored in general.

Thus, Sea-Tac (SEA) is actually KSEA; Paine Field (PAE) is KPAE, San Francisco (SFO) is actually KSFO, etc.

There are so many airports in America, however, that most of the smaller ones don't have descriptive abbreviations. Jefferson County, for instance, is 0S9, while Langley is W10. Not that most (if any) of you all care. :D
