Sometimes some members use codes to identify airlines and that can get confusing.
Here are some common airline codes:
AA: American Airlines
BA: British Airways
CO: Continental
DL: Delta
NW: Northwest
UA: United
US: USAirways
And here are some more obscure ones:
LY: El Al
FL: Airtran
WN: Southwest
B6: Jetblue
F9: Frontier
LH: Lufthansa
Airport codes:
EWR: Newark
LGA: New York Laguardia
JFK: New York Kennedy
LAX: Los Angeles
Feel free to add other codes, but better yet to just try to spell out any hard codes.
