Carl,
Thanks again for the good info. I wont be buying the tix, so no miles on that end, but I plan on using the SWUs to upgrade on the way back to the states and i will want to sleep. (I will be on the 777 so no flat bed for awhile in C) I have spent enough time in F (ex-UAL employee) to know that I like it there more than C, not sure I want to use miles to get it, but I will see how the miles rack up and decide then.
thanks again...take care
