An Air Canada flight carrying 221 passengers bound for Seoul, South Korea made an abrupt return to Vancouver an hour into its flight.

Flight AC063 landed at YVR airport at around 2:30 p.m. after a flight attendant fell ill shortly into the flight, Angela Mah, a spokeswoman for Air Canada, confirmed in an email.

No emergency was declared in flight, Mah said.

She said no fuel dumping was required in flight, and the landing was routine.

Any emergency response vehicles that attended would have been there as a standard precaution, Mah said.

The flight will take off as soon as it is re-crewed, she added.

An employee of the YVR Airport Authority said the aircraft is a Boeing 767-300.

There is no word yet on the condition of the flight attendant.
