code for Nassau
 

Does the code for Nassau, Bahamas work on NW's website ever? It always makes me choose it from a list after I search using the code NAS. Is this a glitch?

The problem appears to exist because NW has a handful of Naval Air Stations (NAS) in their airport database. So, when you search MSP -> NAS for example, it's not sure whether you mean Nassau, Bahamas or Brunswick NAS, ME (NHZ), etc..

The quick fix for the interim would be to search using "Nassau" instead of "NAS", but...

They should probably remove all of the Naval Air Station listings from the airports database as I don't believe any of them offer commercial air service, let alone NW-operated or partner service to said Naval Air Stations...
