Airport security rules and regulations re: photography. Can I take personal pictures?

Question

My wife is coming to the USA for the 1st time. She lands at Chicago's O'Hare International and I was planning on joining/meeting her there before continuing on her DOMESTIC leg home to Detroit. My question is, will I be allowed to snap a picture or two of her emerging from the gates to the visitor's lounge using a digital camera or not? For memories sake.

Answer 1

Yes, as long as you are not taking pictures (or appearing to take pictures) of the security checkpoint, TSA personnel, etc.

Answer 2

yes.

did that before
