All Nippon Airways Mileage Club - Is it possible to request mileage if I enrolled ANA after taking the flight?

I did not find the answer to this question, but is it possible to reqest the mileage for the flight before I enrolled in ANA program? Can it be done online or do I need to send the boarding pass and ticket to ANA?

I think you have to become a member before or when you fly. With my experience with AA, I got declined when I tried to do the same thing. I think the same rule applies to NH too. It's still worth giving it a try though.

no way you can get the miles

I know UA and CX can credit the mileage for the flight 3 months before the enrollment. But I can not get the answer from ANA answer. AA's rule can not be applied to ANA. So unless you have proof, you can not make the conclusion.

Have you tried looking at ANA website?

To register miles for an international flight retroactively, you must submit your registration by mail.

If you forget to register in advance or you find that your miles have not accrued correctly, send the following confirmation documents along with a memo stating your ANA Mileage Club customer number and name to the Retroactive Registration Desk, ANA Mileage Club Service Center within 6 months of boarding (valid postmark required).

* Flights taken prior to becoming a member may be registered if the registration papers are received within 6 months of the flight (valid postmark required).
* Please allow about 1 month for the application to be processed.

Nope.

Called ANA and confirmed it is OK.
