The retractable handle on my carry-on bag refused to extend after this flight. I had to struggle to get to my next gate. I am elderly, and have back problems. All I needed was a way to pull my carry-on, but no one could help me. Finally I got a wheelchair to carry me and my bag, and managed to get to the gate on time. I would like to suggest that you make available some kind of device to offer people to transport their bags if they break in transit. It would be simple and a great service. They could be available at many places in the airport and could be turned in at the front of the airport as people leave, or at the departure gate.
