Just a point of clarification, just because it's marketed and operated by CO and even bought from CO doesn't mean it can't be out of sync. It most certainly can be out of sync.

That's likely not your case here since you received the first of two upgrades.

Since CO's upgrade system is opaque, and you have no visibility into it (no Upgrade: Pending or Upgrade: Waitlisted notation), you just have to have blind faith that the system will work and take care of you if appropriate.

It's unfortunate that they don't have a DL-like or UA-like system where they run upgrade as soon as space is available inside your window, but CO is probably working around a lousy back end system, and apparently this is the best they can do.
