Yes, but asking a local resident to take you to "Kennedy" would work great.Travel agents have almost completely disappeared and DIY bookings make up something like 99% of all tickets sold in the US. As a result nearby major airport codes have become common knowledge among average everyday people. If you asked a working age local resident to take you to "MSY" you'd probably be asked if you meant the airport. On the other hand if you asked a local resident from generation X/Y/M to take you to "Idlewild" you'd probably get nothing but weird looks and shoulder shrugs because nobody other than air geeks would have any clue what the heck you were talking about.Back in the days JFK was not even JFK. It was Idlewild. Most airports are not referred to by their IATA code by anyone other than the air-geeks. Orlando International is known colloquially as OIA, not MCO. I have not heard any man on the street in Newark call Newark Airport EWR. If you tell a taxi driver in New Orleans that you want to go to MSY he'll probably look at you strangely.
