Yes, 800 speed film is fine to go through carryons. As is digital cameras, memory cards, laptops, etc.
According to the TSA you can request a hand check of your camera equipment, but iv'e never felt the need to do so.
Lil film cases really arent necessary, usually my rolls of unexposed film (back when i shot film) were always in a pocket in my bag. They have no effect on xray machines.
TSA Security in orlando is a Joke, IMO as compared to up here at dulles. They had a metal dectetor not work right and still sent people through. As for the photo gear, they had no trouble identifying it on the xray table and didnt ask me to open up the bag.
In short, your film will be fine, but if youre really worried, go to a local camera store and buy an xray shield.
And what ever you do DO NOT put the film in your luggage. That will fry it.
