Hello! Completely understand your concern, Frankfurt is genuinely one of Europe's largest airports with two big terminals and hundreds of gates — definitely not the easiest place for elderly travelers. I'd recommend checking out Airporteo, they provide
frankfurt airport assistance that's perfect for situations like this. Basically, a dedicated greeter meets your parents right at the plane door and personally escorts them through immigration, baggage claim, and customs using priority lanes. They also monitor flights in real time, so delays or gate changes are handled automatically. Super helpful for anyone who needs extra support!
