A collegue of mine said she was able to get it retroactive, but it may have been because she signed up on a certain day. The person on the phone asked her if she wanted to start on march 1st or Feb 16th and it was the 16th or 17th. So she did it retroactively. Maybe she got lucky.

The starting day can be retroactive, but any flights that have posted already will definitely not count.
