IndigoEyes, I think you may be misinterepreting the OP's question.

You note, quite correctly, that is it usual when you're bumped from one carrier to another to get miles credit on both if you play it right, and they are not in the same "alliance". For instance, if you were booked on United, they cancelled and put you on Delta, you could get miles both on United (for the original routing => ORC) and on Delta (for the actual routes flown).

As I read it, the OP is asking whether (a) this would work on members of the same alliance, and (b) if so, whether you could get both ORC and actual routes flown credit posted to the same account. For example, book on Northwest, get bumped to Delta and have both ORC and actual miles posted to your Delta Sky Miles (or Air France Flying Blue) account.

In my experience, if you're rebooked on a carrier in the same alliance, you can get either ORC or actual miles flown, even if you credit them to different accounts in the same alliance. For example, if I was booked on United and they cancelled and rebooked me on Lufthansa, I could get actual miles on Lufthansa's Miles and More, or, if I wrote to United, get ORC on United's Mileage Plus, but usually not both, since United would see that I had listed my Miles and More number on the boarding pass of the flight I actually took.

There are reports of people managing to get dual credit on programs in the same alliance by not giving any FF program when taking the flight actually flown, and then asking for retro-credit on that carrier as well as ORC on the originally-booked carrier. Since many carriers require you to send in the boarding passes for retro-credit and for ORC, that might be difficult to do (you only have one original boarding pass, after all).

However, the second part of the OP's question makes it more difficult -- in that case you're asking for one program to essentially give you double credit for the same flight coupon, and I have never heard of that happening. It is similar to asking United to give you double credit when they cancel one flight and rebook you on their flight on the same routing one hour later.

As I say, I've never heard of it being done, but I suppose one could always ask.
