You can convert your Marriott Bonvoy points into Avios at the following rates: 9,000 Marriott Bonvoy points into 3,000 Avios. 30,000 Marriott Bonvoy points into 10,000 Avios. 60,000 Marriott Bonvoy points into 20,000 Avios.

Yes, you can transfer Marriott Bonvoy points to British Airways Executive Club (Avios) at a standard ratio of 3:1. For every 3,000 Marriott points you transfer, you receive 1,000 Avios. As of 2026, Marriott continues to offer a valuable "transfer bonus": for every 60,000 Bonvoy points you transfer in a single transaction, Marriott adds an extra 5,000 miles, resulting in a total of 25,000 Avios. This makes Marriott one of the most flexible "bridge" currencies for airline miles. To initiate the transfer, you must log into your Marriott Bonvoy account, navigate to the "Transfer Points to Miles" section, and enter your British Airways Executive Club details. The transfer typically takes between 24 hours and 7 days to reflect in your Avios balance. While this is a great way to top off an account for a specific flight reward, it is important to calculate the value first, as Bonvoy points are often worth more when redeemed for high-end hotel stays rather than being converted into airline currency at the 3:1 rate.
