I hope you don't mind if I use this thread to update you all about this:

Does anyone have very recent experiences with this?

As some of you may know (I opened a thread about my trip months ago) I'm about to fly to LAX in a couple of days from Italy (stopover in Frankfurt).
I'm very very concerned about film now. I'll be going through the security checkpoint at LAX on my return flight and obviously I'll have my 4x5 film boxes with the original seals broken.
How am I going to go back home without having a thousand dollars worth of film fried?
Even if I ask for a hand check, should I provide them with my changing bag?
This thought is already ruining my vacation.
