If you are taking a Rollie TLR then you will not have a ton of do-dads. Best to pocket filters etc. and the amount of film you think you will need for the day. Tripods are a definite no go these days. Silly really, what do they think they are, rocket launchers or something?

I do a ton of travelling and I never have them hand search my film. It goes as carry on and I've never had any film fogged.
