I second that “carry what you can carry” attitude, but hey, different cultures I guess.
Traveling solo with fractured ankle in a plaster, having zero free hands when walking on crutches and having different levels of WHCS assistance among different airports has teached me to expect nothing, carry no baggage I can’t carry on my own, despite most people in Europe being nice to you :-)
What do these people do when the leave the aircraft or the airport?
edit: re: japan - I felt almost ashamed with the locals trying to help me in every way, I just wanted to do things on my own, my pace :-)
