What gives is non-revving is an art form, it’s luck and you’re playing the odds.
1. Nothing is guaranteed - not the flight, not your seat, not even that you and your fiancée will be travelling on the same plane.
2. Hawaii typically has high non-rev loads- my advice avoid the stress and get the cheap tickets.
3. Your best source of info is always your sponsoring employee and read the NRTP guide again it will help.
And finally it’s a no-no to link to the AA site, I deleted the link.
