The latest set of rules laid out in the passenger bill of rights is not making everyone happy. Namely, some of the major Canadian airlines. Air Canada, along with Porter, two industry groups, and 15 other airlines are fighting against the passenger bill of rights. The group filed a legal challenge to the bill, which includes offering up to $2,400 to passengers who are bumped from flights.\nThe group of airlines claimed in their filing that the regulations set out in the bill of rights exceed the authority of the Canadian Transportation Agency (CTA). They also argued that the bill of rights is in breach of the Montreal Convention.\nHowever, Canada's Attorney General, David Lametti, has called the filing "ill-founded." According to the Canadian Press, he believes that the case should be completely dismissed. Likewise, the CTA will argue that the appeal should be dismissed if it makes it to court.\nThe passenger bill of rights comes at a time when customer frustration with airlines is high. In February 2019, Air Canada went back on a promise to a passenger to provide an $800-voucher for giving up his seat on a flight. Instead, they only offered him a 15 percent discount on a future flight.\nOther people have expressed annoyance at Air Canada's treatment of its passengers on Twitter.\nHey @AirCanada: A glitch in your system that did not allow me to pay for my luggage ahead of time-either online or at the kiosk- meant that I had to line up unnecessarily for just under an hour for "check in assistance".. &all the agent had to say was "it should have worked". 😡— Krisztina Szabo (@KSzabs72) July 30, 2019\n#aircanada way to over sell the fight form DFW to YUL. A confirmed seat when you book means nothing!— patrioticTxgirl (@TxgirlPatriotic) July 29, 2019\nGotta love it when @AirCanada delays your flight three different times for a total of almost 8 hours and you return to pay over $200 overtime parking fees... #Classic #Somethingsneverchange— Jeff Dadson (@jeffdadson) July 30, 2019\nHeld hostages for over half an hour by @AirCanada in the hottest of #frankfurtairport terminal with no explanations given.

Passengers still have to provide just cause for compensation, and usually, that information stays with the airline.
