Hi @ndrbzz !
When I was on Copaxone I had to travel with it in my purse. It wasn’t a long trip but I was nervous that it would still get ruined. You can carry ice packs but like @stumbler had mentioned, def. talk to the workers on that plane. When I did research before traveling, they had mentioned to do this.. I am sure they are trained to deal with passengers that deal with medical needs.
