Hi - I have paid premium eco flights (MEL -> SFO -> BOS). For my wife and I and 3 teenagers.

Two award saver business seats have opened up on the MEL->SFO leg.

When I go to the upgrade section of the flight, it lists the upgrade as being 30k miles + $450, but both segments are waitlisted.

I don't have any status with United.

Do you think it's likely that my upgrade request from MEL->SFO will clear right away?

I guess my other option is to try to cancel the tickets for my wife and I, and book the award saver seats directly, althought the price for the SFO->BOS leg is now expensive.

Thoughts? Thanks.
