I will be traveling from EZE to SCL on Lan before changing over to AA for a return to MIA. I also travel with a carry on when going on AA to Europe and never have a problem with its size (22 inch job from costco, although that 22 inches gets stretched a bit by wheels). My question is will I have a problem bringing this on board at EZE? Would I have to gate check it? I want to have access to it from SCL to MIA.
