Hi Zhiwu,
AirCover for Hosts was initially launched globally by Airbnb on November 16, 2021, during its global winter release event. Unlike other programs that are sometimes rolled out gradually, AirCover was made available to all hosts worldwide at the same time, meaning it was accessible in most countries from the outset.
AirCover replaced Airbnb's previous Host Guarantee, offering expanded protections including $1 million in damage protection, $1 million in liability insurance, protection from income loss due to cancellations, and even expanded coverage for things like deep cleaning and pet damage.
Because AirCover for Hosts was globally accessible from its inception, there was no step-by-step timeline for country-specific rollouts. The global availability ensured that hosts from all Airbnb markets could immediately benefit from this enhanced protection program.
Note that you can only file Aircover within 14 days or if your documentations is not enough, still contact with Airbnb so you can file within the 14 days after checkout of the guest.
I hope this helps.
All the best,
Upfish Management
