Air Canada flight attendants prepare to go on strike

Flight attendants for Canada's largest airline are planning to walk off the job at midnight Saturday. The move could ground all Air Canada flights for more than a week, leaving 130,000 travelers a day stranded, or scrambling for alternate routes. Wages are at the center of the dispute. But as The World's Transportation Correspondent Jeremy Siegel reports, one of the key sticking points is whether - and how much - flight attendants should be paid when planes aren't moving.
