You earn 3 Avios per £1/€1/$1 spent at Airbnb.
During June 2022, however, this is increased to a generous 4.5 Avios per £1/€1/$1.
The only snag is that you MUST book via a dedicated link on ba.com. You will not receive any Avios if you go via the standard Airbnb home page.
The terms and conditions state that you will receive your Avios within 60 days of booking, not 60 days of staying.
In a recent change, you can also now earn Avios for booking Airbnb Experiences.
These are, to quote:
“Enjoy unique experiences designed and hosted by locals that go beyond typical tours or workshops. Experiences offer guests the chance to explore new places and cultures – both virtually or in-person.”
You will usually earn 3 Avios for every £1/€1/$1 spent on Airbnb Experiences.
Again, however, there is a special offer running until 28th June 2022. Airbnb Experiences bookings made by this date will earn 4.5 Avios per £1/€1/$1.
You can find out more about the general offer, including the detailed terms and conditions, on the Airbnb page of ba.com here.
The only reference to this special offer, oddly, is on this promotional page of ba.com.
