Flight Attendants have voted down the latest offer from Air Canada.

The Air Canada component of CUPE has announced that the contract was rejected by 99.1% of flight attendants who cast a vote.

The tentative agreement proposed by Air Canada includes wage increases for workers and introduces a pay structure for time spent working while the aircraft are on the ground.

The proposed increases include a 12 per cent salary boost this year for most junior flight attendants and an 8 per cent raise for senior members, with smaller increases scheduled in the following years.

The deal was proposed last month to end the three-day Air Canada strike.

Legally, flight attendants are barred from any further strike action, and the dispute will be resolved by an arbitrator.
