I take the film (MF black&white) out of the original boxes but leave it in the wrappers and put it in a large ziplok bag and ask for hand inspection. I also carry a nylon-mesh bag to put the ziplok in after inspection. on the few occasions hand inspection couldn't be done I had no problems with x-ray inspection. If this is a once in a lifetime trip I would be cautious about long out dated film perhaps you should check it first. Personally,
I prefer film with a higher ISO even though I use a tripod depth of field and shutter speed can be an issue if it is windy.
