Air Transat TRZ-T will gradually suspend flights on Monday and Tuesday following a 72-hour strike notice from ALPA, the union representing the company’s 700 pilots, Canada-listed tour operator Transat AT said on Sunday.

Air Transat pilots overwhelmingly voted last week to strike if contract talks between the Air Line Pilots Association and the company failed.

The union, which represents more than 700 pilots, and the Montreal-based company have been in talks for a new collective agreement since January.The pilots are seeking better pay, working conditions and job security.

Transat AT, the airline’s operating company, is struggling to turn a profit and reduce debt incurred after a taxpayer bailout early in the COVID-19 pandemic. The company is also facing a battle for the control of its boardroom led by disgruntled investor Pierre Karl Péladeau.
