This is such a useful feature request. I've noticed the same gap with travel apps specifically, when you book a flight or train, you can add it to your calendar, but ground transportation rarely gets the same treatment. A lot of travelers end up juggling separate apps just to remember when their airport pickup or transfer is scheduled.

It would be great if travel and booking platforms treated ground transport as a first class calendar event too, not just flights and hotels. For example, services that handle airport transfers, like https://bestairportlimotoronto.com/ for Toronto pickups, often send confirmation details that could easily sync into a "tour calendar" the same way a flight confirmation does. Bundling that into one itinerary view would genuinely reduce a lot of the back and forth travelers deal with before a trip.
