Are you saying that you have the award reservations and are just trying to select seats. or that you need seats released so that you can get the award reservations in the first place.

If the latter the answer is the same as the many, many times this same question has been asked - no one knows. This information is also in the FAQ.

If the former, are all the remaining seats to choose Preferred or Preferred Plus? Do you have status? If not, I believe that these are released to the general public within 24 hours, but I'm not sure of the specifics.

Cheers.
