At Airbnb, most core flows (search, home booking, map, trips/itinerary, inbox / messaging, the signup/login screen, profile, settings, and the hosting flow for listing your place) are all native. Most screens are built using a declarative abstraction on top of UICollectionView and UITableView.

The Trips tab in the app (itinerary) was actually rewritten in native after originally being implemented using RN.

It’s really too bad that people have this perception of RN’s use at Airbnb. I feel like people assume the whole thing is RN, which couldn’t be more wrong.
