This is true if they have a CPA with AA, but what if the new Eagle were to enter into a code-share agreement with AA just like we have seen with JetBlue since last year. There is no scope limitation when it comes to Codesharing.

So maybe AE cert continues flying all the EMJ's with a CPA but the Executive cert is used to code-share the CRJ's, ATR's, and they would also be free to expand their fleet as they please.
