Two bodies determine different codes. I believe it's IATA, which stands for International Association of Travel Agents (or something to that effect) that determines the two-letter airline code. The airport designator is a combination of the ICAO and the local governments.
AARPA (similar organization to IATA) designates three-letter codes for airlines, but they are infrequently used.

Just out of curiosity (as is everything on this forum) why does Canada use Y before its airport codes?
Also, do airline codes get to be reused after the airline joins the great airline in the sky? Could a airline use TW now that TWA is dead.
