The airline does not ban any specific breeds, however, it strongly discourages travelers from checking pets that are short-nosed, or brachycephalic.
Hawaiian allows one adult dog or cat per kennel, or up to two puppies or kittens of the same breed or litter that are between eight weeks and six months old. Two adult household birds can travel together in the same kennel, as long as they are at least two weeks old. With your pet inside, the kennel cannot weigh more than 70 pounds.
Pets can only travel as checked baggage if the temperature anywhere along the route is between 85 and 20 degrees Fahrenheit. In addition, if temperatures are between 45 and 20 degrees Fahrenheit, you’ll need to supply an acclimation certificate from a veterinarian from within 10 days of travel.
