Yeah they removed the PNR several times and no luck. I checked in this morning and it changed to sapphire luckily. There are 3 in my reservation and upgrading from LAX-PHL as an AA elite on US was a very easy process. The first two upgrades were free and since there was a third, it cost $300. I was happy to pay the $300 to keep everyone in the same reservation to insure elite benefits for our return flight as well.
