WestJet New Master Seniority List (MSL) Release

Dear Members,


The company has released the new WestJet Master Seniority List (MSL). It will also be available on our Member Portal.

If you have not created a profile on the Union website, you can find the instructions HERE.

The MSL is attached and can be accessed by clicking HERE.

As per the Collective Agreement Article 15-2, there will be no further disputes until the next MSL publication dispute period in April 2022.

Implementation Timelines

The following dates have been agreed upon between the Union and the Company for when the MSL will be utilized:

Layoff and recall
In the event we announce any future recalls or layoffs, the finalized MSL will be utilized.

Crew Scheduling Day of Operations – Effective September 22, 2021
On this date, the new MSL will be loaded into the day of tracking system (Sabre Crew Trac). All operational reassignments and reserve call outs that consider Cabin Personnel’s seniority will be determined using the new MSL.

This update is anticipated to occur between 0000-0200. Those on RAM may still be called out utilizing the Inflight Department List until the update is complete.

Crew Planning – Effective November 1, 2021
Construction of the November schedules will commence in late September and will utilize the updated MSL that will be loaded on September 22.

As a reminder, November 2021 schedules will be constructed and published in late October utilizing the current equity-based system.



In Solidarity,
Your CUPE 4070 Executive Team
