Japan Airlines FLY ON Report: Match | StatusMatcher
From ANA Mileage Club Platinum Service
To Japan Airlines FLY ON JMB Sapphire
Contacted JMB through online message after logging into account. Provided a future JAL business class booking number and a screenshot of ANA card with the message. Got a reply within a few days and asked for future travel plans. Provided the info requested and status was matched 1.5 weeks later.
Is it so easy to get OW Sapphire with JAL?

I knew that ANA and JAL are very demanding in giving away Elite status..
