Qatar Airways and Air Canada will begin codesharing when Air Canada launches service between Toronto and Doha next month. Per the agreement, Qatar will put its code on the Air Canada flights, which will operate three times per week beginning Dec. 15, and the passengers in turn will be able to connect to Qatar flights to more than 75 destinations in Africa, Asia and the Middle East, according to Qatar. The agreement crosses alliances; Qatar is a member of the Oneworld alliance, while Air Canada is a Star Alliance member.
