my gf and I will be traveling through South America for the last 3 weeks of April. She is able-bodied and I am c5 quadriplegic that can walk with crutches for short distances/durations (like down the aisle of an airplane). We've traveled extensively in USA, with a bit of Europe and the Caribbean as well. However I believe this will be quite different because for all of that past travel, we've always flown one of the major airlines here (American Airlines, Delta, United, Southwest, etc) and on these airlines the policy is pretty much the same across the board:
I'm able to remain in my wheelchair and check it right at the gate
I'm allowed to bring a carry-on bag containing medical supplies in addition to whatever the standard cary-on allowance for that specific airline and class of ticket
I'm allowed to carry on yet another bag containing my Freewheel (and its parts), which is essentially a 3rd wheel that attaches to my wheelchair allowing me to navigate some rougher terrain
...all this for no additional charge.
I'm starting to get concerned as we look at flights between countries within South America (ex Ecuador to Argentina) and also flights with the same countries. What I've been seeing is some pretty high costs for standard carry-on as well as checked baggage and not much more information on what I'm allowed to bring (paid for or not) medical supplies/equipment-wise.
Does anyone know if there is a standard policy in place of any sort with respect to this in South America?
