The Globe and Mail reports in its Monday edition that Air Canada cancelled flights to the Middle East from Canada on Sunday as U.S. and Israel air strikes against Iran closed airports and disrupted air travel in the region. The Globe's Eric Atkins writes that war in Iran kept major Middle Eastern airports including Dubai, the world's busiest international hub, closed for a second day on Sunday in one of the sharpest aviation shocks in recent years. Key transit airports, including Dubai and Abu Dhabi in the United Arab Emirates and Doha in Qatar, were shut or severely restricted as much of the region's airspace remained closed after U.S. and Israeli strikes killed Iranian Supreme Leader Ayatollah Ali Khamenei. Air Canada said it cancelled direct flights to Tel Aviv and Dubai, UAE, from Toronto Pearson on Sunday. In addition, the following flights from Pearson were also cancelled: Emirates to Dubai, Etihad Airways to Abu Dhabi and Qatar Airways to Doha. Pearson told passengers in an advisory on Sunday they should check with their airlines before coming to the airport. Air Canada's flights to Cairo, Saudi Arabia and Istanbul were not affected. Air Canada typically flies four times a week to Israel and daily to Dubai.
