I fly in two days, so I'll report back as soon as I can. I feel some measure of reassurance from the TSA posters here, and as I mentioned upthread, I've not had any issues with TSA here at MCO (there's no icon for knock on wood, but if there were, it would be inserted here.

Still, as you say, it's always possible to get someone who's having a bad day that could make things difficult. I'll be armed with my doctor's note and hope for the best!
