Flight attendants at both regional and legacy airlines say they're frustrated by what they call low wages and long-standing airline practices of not paying them during the boarding process.

Air Canada flight attendants will begin voting next week on a tentative agreement that raises wages and establishes a pay structure for time worked when aircraft are on the ground.

The tentative agreement, which would run until March 2029, addresses the contentious issue of unpaid work while airplanes are not in the air.
