Looking through this thread, it appears that the UK based members like the change, and the North America members do not.

This is not just complaining that we are not getting as much as we were before. While that is true, the real issue is that BA is giving far less than its competitors are, i.e., AA and LH.

What do I mean? Let's look at a first class award ticket from the U.S. to Europe. On UA or, any Star Carrier using UA miles, it's 100,000 miles. On AA, it's 125,000 miles (even if the flight is on BA metal). On LH, it's 140,000 miles (but I earn 3.25 miles for each mile flown in paid F). And then there is BA: 150,000 miles.

So what has been the change in my travel patterns? I have not flown one revenue flight on BA since the change. I burned up as many miles as I could before they were so horribly devalued and am left with about 160,000 that I will get around to using at some point.

I used to fly BA in paid F between Bangkok and London. No longer. All those flights now go to Singapore Air, although my miles go to LH or UA. Yes, I have to connect through S'pore, but I can live with that, particularly since I can avoid the overnight flight that I was forced to take on BA. And the immeasurably superior service on SQ makes it worthwhile. I like my shiney SQ PPS card.

People in the UK are, in many respects, stuck flying BA. People in North America are not. I had a choice and took my business elsewhere. BA has no one to blame but themselves. If they had not changed their program, I would still be flying them.
