UA mileage earning on AC (Air Canada) operated flights (P now 150%)
I used to go out of my way to fly AC whenever possible, since their in-flight comfort and amenities tend to be the best out of the North American carriers. Recent changes have somewhat soured the experience though:
- 25% mileage earning on what can be some pretty hefty fares, as the OP discovered the hard way
- No advanced seat assignments without additional payment on those same "discount" fares
- No more free bulkhead seating for *G members
Unfortunately AC has joined the US carriers in the trend to milk every possible $ out of customers, and is no longer the shining star it once was. I'll still pick them in paid Biz over any US carrier though...
