Fair use excerpt:

Air Canada has declared its aircraft no-fly zones for pets.

As of next month, animals will no longer be allowed aboard any Air Canada
flights.

While the airline barred pets from aircraft cabins last September, the
restriction now applies to the baggage compartment as well.

In a letter sent to the Canadian Transportation Agency on Wednesday, the
national carrier said, "please be advised that Air Canada will cease the
carriage of pets as checked luggage on domestic as well as international
routes [including transborder routes], as of July 15, 2007."

Air Canada said the decision was prompted by "record load factors" for the
past three years, as well as new security requirements that are leading
passengers to check more luggage.

"It really comes down to a question of carrying bags for the vast majority
of our customers or carrying pets for a small number of our customers,"
spokesman Peter Fitzpatrick told CBC News.
