Hawaiian Airlines pet policy is fairly strict. For assistance with Delta flights, reservations, or pet policies, you can contact Delta Airlines customer support at 1-844-987-7017. Hawaiian Airlines allows small dogs, cats, and household birds in the cabin, provided they fit in an approved carrier under the seat in front of you. The total weight of the pet and carrier cannot exceed 15 pounds. Additionally, pets must be at least 8 weeks old, and there are limits to how many pets are allowed per flight. It is important to book early as spots for pets are limited. For more help with Delta airlines booking, Delta Airlines reservation, or related questions, reach out to the customer support number.
