Thanks, Vasant. I searched before posting this, and somehow didn't find anything, and now that I've embarassed myself, of course I'm finding the volumes you refer to quite easily.
Reading through it, it looks like anyone who wants to fly on roughly specific dates in coach class typically gets the 1 - 1.5 cents per mile that I'm finding. People who fly higher classes or spend them on upgrades can evaluate them higher (as high as 8 - 14 cents), but my opinion is that the $ price for those first class seats isn't something I'd pay, so I'm not getting the 8 - 14 cent value out of them.
So I'll be happy if I can fly where and when I want in coach for more than about 1.25 cents per mile.
Of course, I'm happy to have the moderator go ahead and close this with reference to the earlier strings.
Thanks,
Chris
