Is this a change?
Not sure who uses the CC complimentary upgrades for awards benefit, but I think it is a good one. As we know this has applied to those people we make reservations for even. However this is the new wording, thus have they closed this loop?
Upgrading award tickets
Premier members who are primary cardholders for certain Chase-issued MileagePlus credit cards are eligible for Complimentary Premier Upgrades when traveling on award tickets on United-operated flights. The following credit cards qualify for this benefit:
United MileagePlus Explorer Card
United MileagePlus Explorer Business Card
United MileagePlus Club Card
United MileagePlus Club Business Card
United MileagePlus Presidential PlusSM Card
United MileagePlus Presidential Plus Business Card
Complimentary Premier Upgrades on award tickets will be sorted as indicated in the "Upgrade Confirmation Priority" section above, and prioritized after the lowest paid fare class within each Premier level. This benefit does not apply to companions traveling on award tickets.
