FWIW

Linnea is going to be flying down to BR in July. She'll spend 10 days down there with my brother and family, and she'll fly back with my mom. It's direct, Seattle-New Orleans-Seattle, so no problem with changing planes in some place odd.

That said, Linnea is a bit concerned about getting to her gate herself. And about my mom. Plus my mom may or may not need a wheelchair (probably not, but...) (Last time Linnea flew by herself, I was also flying out elsewhere the same day so I was able to get her to her gate).

So I was looking for a way to get back behind security even without a plane ticket.

Turns out you can. I don't know if it works at all airports, but Seattle and New Orleans do.
