Help with a flying blue award quote
 

Can someone help me find out the number of FB miles required for the following award flight? I am trying to register a new FB account but keep encountering an error.

Jan 10 2020 - JFK-CDG AF 23 or AF 3577
Jan 15 2020 - CDG-JFK AF 22

Hoping for what the award cost would be in both Economy and Premium Economy.
Thanks in advance for anyone's help!

In Economy I am seeing 22,000 miles and €59.12 extra charges for JKF-CDG, only on AF23 (the other flight number doesn't exist that day).
In Premium Economy it is 68,500 miles and €119.16.
You know these stupid prices are due to the dynamic pricing system and they can change at any time. But actually, the first option in Economy doesn't seem too bad to me, compared to the incredibly high bogus surcharges from other carriers on one way flights from the US (namely BA and LH).

Going back on 20th January, I am seeing 30,500 miles and €135.24 taxes (the other AF flights are priced at 22,000 miles and the same taxes). Again, it's dynamic, may change later.
Premium Economy is clocking 68,500 miles and €195.24 bogus nonsense extra: I wouldn't touch it. One option is even as high as 182,000 miles (do they take us for complete mental fools??????)

AF022 is 22,000 miles the day before and the day after (in Economy).

AF3577 is a DL code-share, so it likely exists but is not proposed for FB awards.

AF3577 is a codeshare on DL262, which I am seeing proposed for an FB award for 2,500 miles extra - but only $10.10 in fees/charges/taxes - on the date in question.
