Air Canada's flight attendants went on strike Saturday, as the airline announced a complete shutdown of operations, creating summer travel chaos for its 130,000 daily passengers. Its full 700-flight daily schedule has been scrapped for Saturday.

Summer travelers are facing uncertainty as the clock winds down on a possible strike by Air Canada flight attendants, which the airline said would force it to cancel almost all of its scheduled flights as soon as Saturday.

Air Canada has suspended all its flights as a strike by cabin staff begins - a move the airline said will disrupt travel plans for around 130,000 passengers a day. The union representing more than 10,000 Air Canada flight attendants confirmed the 72-hour industrial action early on Saturday morning.
