On JAL's itinerary, it shows cabin class: D-Business class SKY Suites from SFO to NRT. And cabin class: X-Business class SKY suites from NRT to SFO. Both on 788 Dreamliner
What is D & X class cabins?
Fare class that tells you things like whether you are eligible for upgrade, availability, earning rate, etc.
