This question may have been asked in the past (if so...I apologize for the duplicate question). I am a Premier Platinum (as of 3/3) and am using a Regional Upgrade for an ORD - HNL flight. We are currently "waitlisted" for the upgrade on the flight(s). As all Premier member was put in for the UDU but wanted to increase our chances getting the upgrade so I am going to use our Regional Upgrades (assuming that they clear). My question is this.....does a Regional Upgrade used by Premier Platinum member take precidence over a GS or 1k using the UDU or somone else using miles to upgrade? Just curious? I know would probably not get the UDU on those flights anyway... Thanks and SAFE travels everyone!
