I'm not going down comparison lane, since there's another thread for it. That was just a sidenote I made, while commenting the situation regarding awards and upgrades with points. I personally didn't mention how BAEC may or may not be preferential.

But sure, I'll briefly mention the option of being able to force awards with double redemption rates from revenue buckets with BA. Other than that, there's the GUF2 voucher which is gained at a level of flying quite equal to what's needed for AY+ Platinum. A single GUF2 makes it practically possible to gain up to six upgraded flights in C, if travelling as two persons. But that's beyond the scope of this thread.
