Tactic to stop Flying Blue points expiry

[Jimmyjimmy]

My flying blue points expire at the end of the year, as I am not planning a flight this year I moved points across to Accor.

I then used Amex MR points to top up my remaining flying blue points to 4000 with plans to send these also to Accor.

However I have noticed that after the MR points went across my Flying Blue expiry is now Oct 2024, the MR transfer has extended them.

I know the expiry rules are a flight to extend points from flight, partner points to extend partner points.

So if I move all flying blue points to Accor.
Then move all back to flying blue it would think flying blue would treat them all as partner points and with 2 year expiry.

Does this work? It’s seems so simple I must be missing something?
Thanks

What you miss is that the Accor to FB rate is NOT like Avios to Nectar. There is a massive loss of value if you move one way and then back.

Thanks, that’s makes sense.

I have a similar challenge, I have around 10,000 Flying Blue miles. 400 of those were earned in August 2022 from an Accor stay. Yet on my Flying Blue dashboard, it says that all 10,000 miles will expire end of December 2022… so I have no idea why I’m losing the recently earned 400 miles as well.

Would doing a MR transfer protect all 10,000 miles?
