Heads up, Hawaiian rejected 2 of my 3 flights credited to JetBlue because it was A class, which they say is only eligible for credit if it's an upgrade, and not if bought outright. Guess who will never buying paid first class on Hawaiian again?
The other one credit just fine (same fare class), BTW, so I'm pretty sure they are making it up. The only difference is I paid for those 2 with Ultimate Rewards via the Chase portal.
