2/3. The easiest way to look would be to go to your reservation on JAL's website, scroll all the way down, and look for an Upgrade button on the bottom right. Go through the flow there and you'll see whether there's space available or if you'll be waitlisted for an upgrade seat.
Thank you. Is it possible to check the availability for upgrade award before purchasing the ticket? The Upgradable ticket seems pretty expensive and I do not want to risk it before confirming with available upgrade.
