Thanks for all of the advice/info so far. I've almost made up my mind to do the 1A/K combo for two reasons that were both mentioned in the posts above. 1) Less traffic, and 2) The forward view which I almost forgot about.
And just yesterday my wife was saying that she would really like it if we could get 12A/C. I told her that I would see what I could do.
I'm still concerned about a schedule change. I always take CX 881 because I can sleep very well on planes, even in J class. My actual hope is that CX would protect us on that one if they put 883 back into daylight.
