I want to bring my elderly parents to visit me here in Sweden next year. My father has had a stroke and walks with a walking stick, and my mother has back issues. Neither of them are in a wheelchair, but they both find it very difficult to walk even moderate distances (they're tired out after 100 meters). In my experience, getting from check-in to the gates at Heathrow can be a marathon and a half for myself, so I'm worried about them making it alone.
Will Heathrow be able to offer any services for my parents to help them get from the check-in to the gate area? I would be willing to pay for such a service. If not, do any of the other London airports serving Sweden provide any disabled services?
They have the disabled car badge thing and are on disability benefits, so proving that they have issues should not be an issue (I think).
