My wife recently went under the knife for a knee replacement. If things continue to improve, it appears that we may yet be able to take our long awaited C-class trip to AKL. (Yes, that one. )

My question is whether or not folks here have had good success/no success/meaningless encounters with TSA when presenting the "Joint Replacement" Card that her surgeon gave her.

I'm guessing she'll end up in secondary anyhow, but perhaps other FT'ers have found these cards to be of help.
Thanks and Best, Dave
