This decision from Air Canada stunned me although I have to say I was even more surprised by the nasty comments from pet owners on sites such as cbc.com after the news was reported. I understand that people love their pets and want to take them everywhere with them but really should that desire trump the safety and well being of other passengers? I just can't believe how many people just don't seem to care that HUMANS may suffer for their convenience.____On behalf of allergy/asthma sufferers out there - we don't choose to be allergic. Anti-histamines only help to a degree. Immunotherapy (allergy shots) is extremely time consuming and uncomfortable, and is rarely effective for those with allergies to animals. The only real therapy is to stay away from animals.____Perhaps Air Canada should consider having limited pet-friendly service. Let all those animal lovers sit together on one flight and see how much they enjoy the noise and smells of other people's pets.
