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.
ha ha ha

I've done this. I got miles from both the airline that actually flew me and the airline that I was originally booked on. But I had no problems doing that because the airline that rerouted me was responsible for the problem. I sent them the receipt for the ticket and a letter asking for the miles and they gave them to me.

Now, the question becomes, if you voluntarily give up your seat and get put on another airline, can you ethically double dip?

It has been reported that mileage can be earned on award tickets.

Gaucho, I remember reading about that too. Someone's award ticket was booked into a revenue fare class, and they did indeed earn miles on it. What a bargain!

I got credited with miles on a roundtrip award flight on a European airline early this year - it was only an inter Europe hop so there were not many miles involved. I dutifully posted the details on Flyertalk but was asked to remove the post by a couple of board members - which I did.

Domestically I once flew SFO-MSP-LGA on NW crediting to my AS account. In MSP I was able to use an MVP Upgrade on NW and I got credited twice for the flight from MSP to LGA for some reason.

Often if I do something that requires supervisor override at the airport or on the phone this changes the booking class up to full Y. On a recent East coast trip I asked to change flights to an earlier day because I was worried about a snow delay - this required a supervisor override and was done as a courtesy for no fee (I felt I was helping them out in a sense by easing pressure on a day of disruption). The resulting flights posted as Full Y - had I known at the time I would have spent the (minimal) miles for an upgrade!

Come to think of it, I recall seeing something on the FFF forum about a person who had a poblem with an award ticket they were using so the airline rebooked them in a class that would now earn miles. I believe this can happen and it is legal. The airline chose to do it for them to help with their inconvenience. I'd take it!
