The LATAM Airlines pet policy is as follows:
Pets – only cats and dogs – are accepted in the aircraft cabin.
Pets must be at least 8 weeks old, except in the United States where it must be at least 4 months old.
If your pet doesn’t meet the requirements to travel in the cabin, it must be transported in the hold of the airplane.
Pets in the hold service isn’t available: to or from the Galapagos Islands, Australia, New Zealand, South Africa, Papeete, England and to the Sangster International Airport in Montego Bay, Jamaica; on the Brasilia-Asuncion route operated by Paranair; or on flights connecting with other airlines or code share flights.
Dogs of the “American Bully” breed and cats of the “Cat Breeds (all types)” will not be admitted aboard for transportation as animals in the hold, since these breeds are regarded as dangerous and brachycephalic animals respectively.
If you are traveling to or from New York or Boston between December 15 and March 15, you can only travel with your pet in the cabin; hold transportation services during these months due to low temperatures have been cancelled.
Depending on current weather conditions in both cities, restrictions on pet transportation in the hold may be extended through April 15th.
Taking a pet to a foreign country involves preparation and planning far in advance of your departure date. Requirements for pet travel to a foreign country are set by the destination country. If you are you traveling to another country and bringing along your pet you’ll need to meet the animal health requirements of the country you are visiting.
