I'm not knowledgable on this stuff, but just looking at the CBA, I'm reading this: {in a nutshell and in my own words...}

SCOPE:

1.) All flying must be done by Frontier pilots on one list.

2.) No alter ego airlines allowed.

3.) Code share agreements ARE allowed.

4.) Company can lease or contract out flying, for a limited time period, if necessary, and the company doesn't have the resources/assets/staffing to accomplish it in house.

MERGER:

"Integration shall be in accordance with Sections 2, 3, and 13 of the Labor Protective Provisions specified by the Civil Aeronautics Board in the Allegheny-Mohawk merger ("Allegheny- Mohawk LPP's")."

^^^^ What this means, I have no idea. ^^^^

There is also some language about the company meeting with the association to construct a 'possible fence' in the event of a substantial acquisition - by or of - another company.

Thats all I got putzin - hopefully some more guys will chime in.
