Did you get the terrific travel case from the Humira company when you started the med?
Just pack it in the bag with a few (more than one) ice packs. I've travelled about ten hours with mine packed like that, but I wouldn't want to have stretched it any longer than that. If it's a really long trip, perhaps you could take some unfrozen ice packs and ask the plane or train staff to stick it in their freezer, and then give it to you about eight or ten hours into the trip. Keep exchanging the packs as needed until you've reached your destination.
