This has been in the works since June:

"In June [2025], the union filed a formal policy grievance, and a Toronto-based arbitrator has since been appointed to oversee the case.

While the arbitration process moves forward, the union has also sought an interim order to prevent WestJet from enforcing the policy, according to Lewall.

The WestJet pilots MEC has filed an interim order requiring WestJet management to cease and desist its unilateral implementation of their policy change,” Lewall said.

“We are requesting that WestJet management do the right thing by maintaining the existing status quo, pending the final outcome of this arbitration.”

Lewall is the ALPA MEC Chair.
