Booked a few B6 Mint class flights and used my Singapore airlines FF. After many weeks of no credit I submitted a claim to get the miles posted to account. Just received word from sq that they were denied because “booking fare class not eligible for accrual”.

I called JetBlue and they disputed saying it should credit 125% of miles to SQ as was a Mint class ticket, but that I have to take it up with them.

Anyone had success in resolving this issue with SQ?
