Travelers with disabilities traveling entirely within Canada on Air Canada may bring a personal care attendant free of charge. More details of the policy are available on the Air Canada website.
Air canada also offers 50% off for attendant when going to the US. WestJet also offers free attendant within Canada. WestJet does not offer anything going anywhere else.
Just in case any body missed this buried down further in the article:
“The court’s decision was also extended to obese passengers, who had previously been required to purchase two seats if the space of a single seat was insufficient.”
Such fab news! Thanks for sharing.
