I had an FA go bezerk once when she realized I was taking photos of a sleeping Delta Ramper. Nothing came of it, just received poor service on the flight.

The one area I have had multiple problems is taking photos from the AirTrain at JFK. The inside of the AirTrain and the AirTrain stations are elevated and a great spot to get pictures of JFK. The AirTrain connects all of the terminals at JFK, plus connects the airport with subway at Howard Beach & LIRR at Jamaica Station.

Unfortunately Port Authority Security Guards and the AirTrain "helpers" have all been told to stop all photography. They can get extremely rude and nasty about it as well and won't take no for an answer. Once had a security guard try to go for my camera and it escalated to the point where I just left. If it had been a weekday, I likely would have pushed it further, but it was a Saturday.

I then called the Port Authority on Monday and made some noise -- at the same time I asked what do I have to do to take pictures as a tourist in your city, they gave me permission to take photos. Even with permission it was a challenge to take photos and each time challenged I introduced myself as "The tourist from Louisville who was given permission to take photos"

Apparently it's a sticky situation with the Port Authority. They are a govt entity and run all 3 NYC airports, but they claim to be self-funded from user-fees/rents, thus argue are a private entity. I call BS on this as does a respected attorney I spoke with.

Never had a problem inside the secure areas of JFK, LGA, or EWR snapping photos, but I've seen others hassled inside JFK by Port Authority Security Guards.

To the OP, good on you!
