I'm well aware of Aegean's purchase of OA and as far as I know, there are no plans to merge both airlines but run them separately. As Aegean is a member of *A and OA was not, I was wondering when that changed. If UA is showing availability for A3-marketed, OA-operated flights and Wikipedia lists OA as an affiliate of A3, then OA is part of Star Alliance. Here's the link:

However, Wikipedia's OA page has something that may shed some light on this:
Starting on February 1, 2014 Olympic Air is a service provider for parent company Aegean Airlines, with all the flights carrying the latter's flight prefix. [68] The carrier continues to operate the PSO routes.

It seems that this is similar to Austrian and Tyrolean. A lot of OS flights are operated by Tyrolean just like in this case, starting today, February 1st, a bunch of Aegean flights will be operated by Olympic.
So, I answered my own question.
