Aug 20 (Reuters) - Air Canada ( ACDVF ) is set to resume its

flight services on Wednesday, after a nearly four-day strike by

its unionized flight attendants left more than 500,000

passengers stranded.

"While the restart of our operations will begin immediately,

we expect it will take several days before our operations return

to normal," the airline said.

The flight attendants' union and the airline had on Tuesday

reached a tentative deal, but its details have not been

disclosed. The union said unpaid work was over.

Flight attendants had walked off the job on Saturday after

contract talks with the airline collapsed. They had pushed for

compensation for duties such as boarding passengers.

The airline is yet to reinstate its third-quarter and

full-year profit outlook, which were withdrawn due to the

strike.

The proposed wage hikes at Air Canada ( ACDVF ) would mean up to C$140

million in incremental costs, according to Canaccord Genuity

analyst Matthew Lee.
