Cons:We requested wheelchair assistance for my grandmother (3 days before the flight), but at the departing airport, the person with the wheelchair left early and we had to walk her on to the plane. When we arrived at Hong Kong, there was no wheelchair on the bridge, and after disembarking and being told to wait, it took 30 minutes for them to bring one. The ground staff kept trying to convince us to just walk which seemed very unprofessional.
