This all sounded incredibly like a very San Francisco first world problem, until I thought of one use case for which you could be incredibly useful - old grandparents who don't speak the language traveling internationally on their own. I know mine are always afraid to travel because there is no one to help them on connecting flight to go cross customs on arrival. $300 to help them move doesn't sound all too bad, when combined tickets are already over a grand.
A good solution for grandparents is to ask for wheelchair service. It is usually free and they'll get whisked from the checkin desk all the way to the baggage claim on the other end. If they don't like the idea of sitting in a wheelchair, they can just walk next to the agent.
Yup. Have done that on "both ends," which is really convenient and also allows me or someone else to accompany them directly to the gate. That said, Solve could be a solution in transit. For example, try navigating Schiphol or Heathrow if you don't speak the language, and have a long delay between your connections. There's room there for premium experience.
