Companies in the news:

Air Canada. (TSX:AC). Up 98 cents, or 6.13 per cent, to $16.97. Air Canada had the second-highest number of complaints about refunds to the U.S. Department of Transportation of any airline in May. The department says Air Canada was the target of 1,705 refund complaints out of 10,415 filed against non-U.S. airlines in the month, outpacing all 80-plus foreign carriers in the category as well as more than 45 flight agencies. United Airlines was the only airline — domestic or international — to notch more refund complaints at 3,215. Air Canada and other Canadian carriers have refused to reimburse most customers whose flights were cancelled due to the COVID-19 pandemic, typically offering flight credit instead. However the U.S., like the European Union, requires airlines to refund passengers. A complaint to the U.S. regulator offers a potential path to reimbursement for some Air Canada customers who have been turned down north of the border. Despite the high complaint numbers, Air Canada carries fewer passengers on flights with a U.S. segment than four U.S. airlines as well as British Airways and Lufthansa, according to figures from the U.S. Bureau of Transportation Statistics. WestJet Airlines Ltd. ranks right below Air Canada in cross-border passenger numbers, but garnered the sixth-most refund complaints among non-U.S. airlines at 346. WestJet has said customers who booked U.S. or U.K. flights are entitled to refunds. May marks the second month in a row that Air Canada has finished among the top tier of complaint targets, with the Montreal-based company's portion on the rise.
