Two flights today.
From YVR: boarded 1st, GS, 1K, and CO Plat (I think) through red carpet. Then boarded remaining elites (listing UA and CO levels) as a group through red carpet. Didn't wait around to see what happened

after that. Boarded fairly efficiently.
From ORD: first and all pax of status called onto the red carpet. A bunch of pushing and jostling for space. Rather chaotic at the gate. I had a UDU and was a bit miffed I didn't get a cleaner board experience. But in ordinary life I'm just a 1P so now I get to jockey with the 1Ks

Cool for me but I don't think it is right. Especially as the airlines are now upselling priority boarding and getting real bucks for it.
