We all appreciate wanting UA to be better, but on the p.s. routes it actually is better than the competition. I want to make the following comment in a kind fashion, excuse the wording and please take it that way.
You picked for comparison one route on one very small airline that has launched a business class service precisely because it fails to attract business passengers and has made no headway against Qantas and company in that regard. UA competes primarily with DL and AA on p.s. routes, throw in jet blue and Virgin America if you want. Do you not think p.s. is better already? You need to compare UA to its competition, not selectively choose some domestic route on a different continent out of the blue.
United needs to up its game, but needs to start that process in other areas where it is falling behind its competition.
