Sorry.
BWI?
When you fly a lot you start learning the codes. On the West coast I'm not infrequently in SEA, SAC, OAK, SFO, SJO and LAX. My connections to the East coast are usually through MSP, DTW, MEM, HOU or ATL (rarely PHX or DEN). A savvy flier will spot my preferred airlines from this info.
Furthest from home is BLR (Bangalore, India).
