Delta Airlines has a pet-friendly policy, known as the Delta Airlines pet policy, which allows small dogs and cats to travel in the cabin with their owners. Pets must meet certain age requirements and be in a secure carrier that fits under the seat. For those who prefer cargo transport, Delta's PetSafe program, a part of their pet policy, ensures the safety and comfort of pets. Before booking a flight for your pet, you must visit the airlinespetpolicy website once to get complete information about the pet policy.
