I need to pick a *A FFP to credit my upcoming trips to. I am reeling from trying to compare different *A programs with their complicated rules and poorly worded descriptions. Pretty much all the FFPs I checked so far had a deal breaker... is there any decent FFP left?

My upcoming trips (already booked but I didn't add FF numbers to any):

Dec 31-Jan 7 AMS-LAX in biz return, ticketed and flown on United (myself)
4 additional family members on the same flight, flying economy - all of them can be credited to family account (which I understand is a benefit of Aeroplan)

Jan 23-Feb 4 AMS-BOM biz on Etihad

I have more flights during 2022, this is just the beginning. I expect to fly at least 40-60k miles during 2022.

So given these flights, that I am based near AMS, and that I mostly fly EU-US and EU-Asia routes, can someone confirm or deny that crediting all of my flights to Aeroplan would be a good choice? If not, is there a better option?

My main goal with a FFP is to earn *A upgrades. The last program I checked (Asiana) looked great, until I learned that point upgrades are pretty much limited to upgrading from B/Y, which makes them pretty much useless. I hope that's not a general rule in *A and some programs are better.

Thank you!
