What is the Marriott Bonvoy to Avios transfer ratio?

The base rate is 3:1 — three Marriott Bonvoy points for one Avios. However, transferring 60,000 points in a single transaction triggers a 5,000-Avios bonus, giving 25,000 Avios instead of 20,000.

How does the 60,000 point bonus work?

For every 60,000 Marriott Bonvoy points moved in one transaction you receive 20,000 Avios at 3:1 plus a 5,000-Avios bonus, for 25,000 Avios. This is a permanent, published feature of the transfer, not a limited-time promotion.

How long does a Marriott to Avios transfer take?

Typically one to five business days. It is not instant, so never rely on it for a same-day booking — transfer well before you need the Avios, but only once the reward seat is confirmed available.

What are the Marriott transfer limits?

You can move between 3,000 and 240,000 Marriott Bonvoy points per day. To maximise the bonus, transfer in exact multiples of 60,000 so each block earns the 5,000-Avios bonus.

Which Avios programmes can I transfer Marriott points to?

Marriott transfers into the Avios family, so you can direct points to British Airways, Iberia, Aer Lingus, Qatar Privilege Club or Vueling — and then move them between those programmes at 1:1.

Is transferring Marriott points to Avios a good idea?

It is the best hotel-to-Avios transfer, but hotel points are often still worth more as hotel nights. Transfer when you have surplus Bonvoy points or need to top up for a specific Avios redemption, ideally in 60,000-point blocks.

Marriott Bonvoy to Avios

The best hotel-to-Avios route there is. Transfer in the right size and 60,000 Marriott points become 25,000 Avios. Here is exactly how the bonus works and how to use it.

Last updated: September 2026 6 min read

Marriott Bonvoy is the one hotel programme where transferring to Avios makes real sense, thanks to a permanent bonus on large transfers. Get the transfer size right and you lift the effective rate well above the 3:1 headline.

The rate & bonus How to transfer Limits & timing Is it worth it?

1. The rate and the bonus

Marriott Bonvoy converts to Avios at a base 3:1. The clever part is the large-transfer bonus: move exactly 60,000 points in one transaction and you receive 20,000 Avios at 3:1 plus 5,000 bonus Avios — 25,000 Avios in total. That lifts the effective rate to 2.4:1.

Always transfer in exact multiples of 60,000. Each 60,000-point block earns its own 5,000-Avios bonus; odd amounts in between just convert at the plain 3:1 with no bonus.

2. How to transfer

1Log in to your Marriott Bonvoy account and open the points transfer / convert to airline miles tool.

2Choose your Avios programme — British Airways, Iberia, Aer Lingus, Qatar or Vueling.

3Enter the amount in multiples of 60,000 to capture the 5,000-Avios bonus on each block.

4Submit and wait — the Avios typically arrive within one to five business days.

Because it takes days, this is not a route for grabbing a seat you have just found. Keep a working Avios balance and use Marriott to replenish it, not to make a last-minute booking.

3. Limits and timing

Daily limits. You can move between 3,000 and 240,000 Bonvoy points per day — up to four 60,000-point bonus blocks in a single day.

Processing time. Allow one to five business days for the Avios to appear — plan ahead of any deadline.

Pick the right programme. Send the Avios to whichever programme prices your flight cheapest, or pool later via account consolidation.

4. Is it worth it?

Marriott is the best hotel-to-Avios transfer, but remember Bonvoy points can also be worth a lot as hotel nights. Transfer to Avios when you have surplus points, when you are topping up for a specific redemption, or when a rare airline transfer bonus stacks on top. For the wider comparison, see hotel points to Avios.

Only transfer what you will actually use. Avios can be devalued over time, so do not stockpile far beyond a redemption you are planning.
