There will be a rebranding in the next ten years. Airbnb will get a slightly more blocky or rounded version of the same logo and ads everywhere announcing how "Airbnb is now Air".

I can't tell who owns air.com, but the website it hosts is a tiny landing page from someone who would obviously sell.

The rebranding will be met by a slew of astonished articles asking "they spent how much?" and almost as many apparently-thoughtful midwit counterpoints saying no, it looks obvious in hindsight, but it took real marketing genius to conceive of this in advance.
