I seem to have been misinterpreted multiple times

From what I recall, the CX flight out of YVR is a red eye, I don't get what you mean by noon. It leaves closer to midnight and arrives at the crack of dawn. Availability hasn't been so hot recently either even on short notice.

Iberia metal destination comment was from the perspective of Spain to north America, especially the west coast. Obviously they have a domestic network. JFK, ORD and lax are perhaps the best choices for someone out of the west coast, but again, additional cost. Taking the bus to Seattle doesn't really help me in this case anyways? (Not that I would with an infant)

Alaska plus Iberia suggestion is still 59k (and Alaska miles are much harder to earn in Canada than Aeroplan with only one credit card partner), versus the 45k today and 55k in the future.

Taking Lufthansa after taking a no yq carrier like Swiss across the ocean doesn't incur fuel surcharges. YUL to FRA in economy on the first date I looked at Feb 10 is an example (Swiss to LH).

I was comparing Aeroplan to other ff programs going to Hong Kong. In that context it's hardly the worst. Even with the 25 percent Mr to Avios bonus it's still 144k which is only better

I for one don't earn many miles from cc spending, here it's more about sign-up bonuses for non flyers. In Canada there's what, 7 Aeroplan credit cards not including membership rewards charge cards? Heck even one Aeroplan amex referral gave more miles than half a year's worth of spending

Signup and transfer bonuses for BA and Asia miles here are much rarer in comparison. I don't live in Hong Kong, so how they earn doesn't mean much here (versus US credit cards which we can get some exposure to).

In the end, moving away completely from Aeroplan in Canada seems like cutting your nose to spite...somebody. You work with what you have, avoiding it completely send extremely short sighted to me. There's nothing stopping anybody from collecting multiple programs, the only real decision is whether to transfer amex Mr to Aeroplan or Avios. This is the first amex BA transfer bonus in two years, and I'm not sure they're going to bring it back anytime soon with the terrible Canadian dollar and the fact that the US amex Mr program is about to devalue themselves too.

Avios has its uses, but post devaluation I'm in no way going to use it for anything beyond band 3 going forward due to the triple cost for anything in band 4 onwards and because Aeroplan's routing rules for roundtrip are just so much more flexible with the two stops plus destination, not to mention the best infant ticket policy among major programs.

You keep mentioning huge earnings for full fare business and first class, but that's a completely different world from me (and perhaps the majority of Canadians?). Between discounted economy, very rare premium economy and the very occasional deep discounted business class fare (like the 1.6k star alliance or 2k one world), earnings across programs don't differ all that much, with 25 percent flight miles on discounted CX/Tango Canada and up to 125 percent flight miles on star p or one world I fares being the reality for someone like me who flies on their own dime.
