Hi @Andrew536 ,
yes, as @Rene & Zac have indicated they are planning on launching an own airline. The name will be Airbnb-Force.
The big thing about this new airline will be, that every guest that flys with Airbnb-Force will be granted a 24h around the clock check in time at the place of arrival. So if an airbnb-guest flys from NY to London and his London host has sipulated a check in time from 3pm to 5pm, this will be superseeded by the Airbnb-Force regulation that he can check in anytime, e.g. 2am.
This is a strong sellingpoint and a feature other airlines cannot compete with.
