I would say it would depend on what exactly they needed to do for you, such as stop for the bathroom, stop for food, wait for your luggage and then take it to your transportation, etc. Mine took me from the plane through immigration and then left me in the luggage area, in the wheelchair, as we had a long, long wait ahead of us, and I was mobile. We never saw him again. I think my husband gave him $5. If he had needed to do any of the above, it would have definitely been a larger amount.
