Now that ExpertFlyer is down for *A (RIP), is there any way to check PP upgrade availability on NH? I want to book a west coast to Japan trip on Jan 31 and upgrade with PP, but I don’t want to pay the higher cost for the upgradable fare code if it’s not pretty much guaranteed to clear.
I supposed I could book it, immediately try to upgrade it, and if it doesn’t work cancel it for a refund within 24 hours? Do I have any other options?
