My wife and I both use canes. Although I had checked in 24 hours before the flight and noted we would be checking two roll-on bags, the machines at the check in area did not produce luggage tags, and staff were unwilling to help unless we joined the long queue, a very difficult challenge. We opted to take the bags on board and, of course, were relieved of the jells and scissors in the bags at security. On board crew were then unhelpful in hoisting the bags into the overhead bins.
