Delta allows each passenger to check up to two pet kennels, or carry on one kennel as long as the flight hasn't reached its pet carry-on limit. Guidelines vary depending on the pet travel method. Delta provides pet travel information on Delta.com, as of 2015.
To view pet travel information, visitors to Delta.com should place the cursor over Traveling With Us, and click Special Assistance on the drop-down menu that appears. They should click on Pets to view that page. It offers links for pet travel requirements and restrictions, and pet travel options.
The pet travel requirements and restrictions page has options for health, kennel and weather requirements. Other options include animal breed and aircraft restrictions. Clicking on any option brings up information about it.
Health requirements include a health certificate issued by a veterinarian and offering the pet food and water within four hours of the flight. Kennels must meet size requirements and have the necessary labels. Weather requirements vary based on the season and area. Breed restrictions lists animal breeds that Delta doesn't transport, while aircraft restrictions lists restrictions that apply to specific aircraft.
Pet travel options include taking the pet as a carry on, checking the pet, and shipping the pet as cargo. Fees vary for each method.
