K. Integrated Seniority List (ISL). The seniority lists of the Pinnacle, Mesaba, and Colgan pilots will be integrated pursuant to the protocol attached hereto as Attachment B. The Pinnacle, Mesaba and Colgan MECs will complete the seniority list integration process so that the ISL will be established, either by agreement or through arbitration, no later than 135 days after a full language tentative JCBA has been reached, subject to such additional time as may be required by sections 7b and 7c of Attachment B and modest changes in schedule approved under section 12 of Attachment B.

L. Acceptance of the Integrated Seniority List. Subject only to the conditions stated below, Pinnacle, Mesaba and Colgan will accept the ISL reached pursuant to the attached protocol and incorporate the ISL in the JCBA. The ISL shall only have prospective effect and shall not be implemented prior to the JCBA. Specifically, and without limiting the generality of the foregoing, the following conditions shall apply:

1. There shall be no “system flush” whereby a pilot may displace another pilot from the latter's position as a result of the implementation of the ISL or the implementation or expiration of any conditions or restrictions; and

2. Pilots on furlough status at the time the ISL is implemented may not bump or displace pilots in active status at that time; and

3. Pilots who, at the time of the Integrated Seniority List, are in the process of completing or who have completed qualification training for a new position (e.g. CRJ 900 CA or Q-400 F/O) will be deemed to occupy the position for which they are being or have been trained, regardless of their relative standing on the ISL.

M. Information for Seniority List Integration. Subject to the execution of appropriate Confidentiality Agreements and legal requirements, Pinnacle, Mesaba and Colgan will promptly provide the MECs with reasonably requested employment or other data and information for the purpose of integrating the seniority lists. Any data or information provided to one MEC shall simultaneously be provided to both other MECs.
