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 will gradually restart operations after reaching an agreement with the union for 10,000 flight attendants to end a strike that disrupted travel plans for hundreds of thousands of travelers.

The strike, which ended on Tuesday, focused attention on why many airlines don’t start paying flight attendants until the plane doors are shut.
