loyalty IS dead:

i used giftrewards.com to get points that give me AA miles.
I bought something on there that eventually led to US AIr miles.
I charged it with a Northwest visa card.
I flew on US air and put the miles on UAL.
I got enough ual to get a free ticket and used it on DL.
They made an error in booking and put me on an AA eagle shuttle, which is something DL partners with and this gave me more miles on AA.

on the way back, I flew UAL and asked them to put the domestic portion on DL, and the int'l portion on Singapore Airlines and they screwed up and put it all on my air nz acct!

Now, none of this REALLY happened, but it sure could have! exactly like I say! You would have like 3,000 miles on all of them which is nothin.
