WestJet accepts small pets in the cabin and as checked baggage on most international flights. Dogs and cats are not accepted on flights to, from or through Barbados, Hawaii, Ireland, Jamaica or the United Kingdom in carry-on or checked baggage. Although WestJet accepts pets other than cats and dogs, other animal types (species) may not be permitted or may have additional entrance requirements for other countries. Due to extreme heat, on certain flights pets are not accepted in checked baggage annually from May 1 to October 31. WestJet Cargo accepts pets travelling on their own. If you wish to transport an unaccompanied pet, please contact WestJet Cargo for rates and information at 1-866-952-2746 (1-866-WJCARGO).
