I do have a good reason. I am looking for award flights between US and the Middle East and while both airlines are members of SkyTeam there is a definite advantage to Flying Blue but this I found out after pouring tens of thousands of miles into Delta
If I could move my miles I could almost get a ticket even with a "loss" as opposed to having to fly a lot lot more on Delta
