All Nippon Airways Mileage Club - Best way to request mileage credit

This is a bit complicated.

I booked a flight on UA, connection on ANA. The outbound return on ANA had a mechanical problem making us miss our UA connection. Rebooked on AA. The agent we spoke to said she had spoken to her supervisor and that ANA would give us mileage credit on our UA accounts for the UA flights we misconnected on. It's about 7000 miles. I'm particularly concerned about losing the elite qualifying miles.

What is the best way to go about requesting this credit? I'm in the US.

(I was quite put out as ANA cancelled our connection on UA. The UA flight was delayed and we could have reached our UA connection before the doors were closed. But UA had given away our seats because ANA had cancelled us and rebooked on AA. The agents refused to rebook us on any *A flight.)

Thanks for the help.

request original routing credit....

Thanks. I should have been clearer in my question, how (what method) should I request the credit. On the ANA page, it appears the only avenue is to mail the request for missing mileage. I was wondering whether there was an on-line way to ask for the credit.

Since you have special circumstances, I would call NH rather than requesting the credit online.

Thanks

You will likely need to submit documentation vial mail to LAX CTO/AMC offices.

I've always sent documentation and a cover letter explaining what I want via mail to NH's LA office. Never had an issue and have always received proper credit in 2-4 weeks.

If you call, they'll notate your account, give you the address, and tell you what paperwork needs to be included.
