Because of my prospective travel schedule in 2016, I'm considering switching from AC to United (not because I'm pissed off at AC/Aeroplan, but because I will likely be travelling far more segments/miles on UA). I am currently SE (past 4 years) with little hope of million mile, so I'm not concerned about that. I've never found that UA treats *G passengers that well - Group 2 boarding, limited complimentary access to PE seats, rarely upgraded (I'm silver on Delta and get upgraded way more frequently than on United). With the AC requirements for AC metal flights and $$$, I'll struggle to meet requirements for 2017 given far more frequent domestic US travel than transborder. UA will not status match AC, as far as I know....is there a way to get appropriate treatment and accumulate miles on United with recognition of my *G status without getting treated as a "new" customer? In the past I was told to book using my *G (i.e. AC FF #) and afterwards submit a change to the MP number (i.e. submit boarding pass, etc.) after the flight. I won't be doing this as I will travel 100 to 120 segments next year and it creates too much work for both the airline and I, with too much opportunity for error, need for me to track, etc. The easy switch, it seems, would be to have American status match, and then in future, status match back to Aeroplan when I return to more trans-border travel. Any experience or thoughts on a more elegant approach?
