Hawaii Airlines Dog Policy – All You Need To Know
I’ll never forget the first time I tried to fly with my dog between the islands. I thought it would be simple: small dog, carrier, plane, done.
But when I got to the airport, I realized that even a short flight within Hawaii had its own set of rules. The carrier needed to be a certain size, the dog had to stay under the seat, and not all flights even allowed in-cabin pets.
I spent hours researching, making calls, and measuring my dog’s crate until I finally figured out how to make it work.
Traveling with dogs is full of small challenges that can easily be overlooked. From the right carrier to understanding which flights allow pets, there is a lot to consider.
Over time, I learned that Hawaiian Airlines dog policy is strict but fair, and knowing the rules makes the experience smooth and stress-free, for both you and your dog.

Hawaiian Airlines Unique Features

| No pets on international flights — cabin or checked. |
| Checked baggage pets limited by seasonal embargo & route weather restrictions. |
| Only one kennel per passenger; limited spots per flight. |

Cabin Pet Limits
Hawaiian Airlines limits the number of pets allowed in the cabin per flight. This ensures safety and comfort for both passengers and animals.
Even small dogs may be denied boarding if the flight quota is full, so booking in advance is essential. Weight restrictions are strictly enforced, and only dogs within the allowed weight range can fly in-cabin.
| Max Pets Allowed | Carrier Dimensions (cm) | Flight Class | Notes |
| 2 | 48x33x27 | Economy | Reservation required |
| 2 | 48x33x27 | Economy | Reservation required |
| 2 | 48x33x27 | Economy | Reservation required |
Kennel & Under‑Seat Rule
For in-cabin travel, the kennel must fit under the seat and be well-ventilated. Hawaiian Airlines enforces exact carrier dimensions, and carriers that are too large or too soft may be rejected at check-in.
Your dog should be able to stand, turn around, and lie down comfortably within the carrier.
| Carrier Type | Max Dog Weight | Dimensions (cm) | Flight Class |
| Soft-sided | 9 kg | 48x33x27 | Economy |
| Hard-sided | 9 kg | 48x33x27 | Economy |
| Soft-sided | 8 kg | 45x30x25 | Economy |
| Soft-sided | 7 kg | 45x30x25 | Economy |
No Checked/Cargo Pets
Unlike some airlines, Hawaiian Airlines does not allow dogs in checked baggage or cargo. All dogs must travel in-cabin.
This policy reduces stress for the animal but requires strict adherence to weight and carrier dimensions.
| Travel Type | Allowed Weight | Restrictions |
| In-Cabin | Up to 9 kg | Max 2 pets per flight |
| Checked | Not allowed | Not permitted |
| Cargo | Not allowed | Not permitted |
Breed & Weather Alerts
Some breeds, especially snub-nosed dogs like Pugs or Bulldogs, are more vulnerable to heat and stress.
Hawaiian Airlines issues breed-specific and weather alerts. Even if your dog meets weight and carrier rules, extreme temperatures can prevent travel to ensure the dog’s safety.
| Breed | Max Weight | Heat Sensitivity | Notes |
| Pug | 8 kg | High | Only allowed in safe temperatures |
| Bulldog | 10 kg | High | Only allowed in safe temperatures |
| Chihuahua | 4 kg | Medium | In-cabin allowed |
| Maltese | 3.5 kg | Low | In-cabin allowed |
| Shih Tzu | 5 kg | Medium | In-cabin allowed |
Advance Reservation Must
Advance reservations are required for all in-cabin pets. Flights have strict limits on the number of pets, so last-minute attempts to bring a dog may fail.
Providing breed, weight, and carrier dimensions when booking ensures compliance and avoids stress at check-in.
| Flight Route | Breed | Reservation Status |
| Honolulu → Maui | Chihuahua | Confirmed |
| Honolulu → Big Island | Yorkie | Confirmed |
| Honolulu → Kauai | Maltese | Confirmed |
| Maui → Honolulu | Shih Tzu | Confirmed |
| Kauai → Honolulu | Pomeranian | Confirmed |
Service Dog Rules
Service dogs are allowed regardless of size or carrier restrictions, provided the correct documentation is presented.
Emotional support dogs are not considered service animals on Hawaiian Airlines, so they must meet the same in-cabin requirements as regular pets.
| Breed | Service Type | Documentation Required | Flight Class |
| Labrador | Guide Dog | Certification | Economy |
| Golden Retriever | Mobility Assistance | Certification | Economy |
| Poodle | Hearing Dog | Certification | Economy |
| German Shepherd | PTSD Support | Certification | Economy |
| Border Collie | Mobility Assistance | Certification | Economy |
Documentation Checklist
Hawaiian Airlines requires a health certificate, vaccination records, and proof of service dog certification when applicable.
International flights may have additional requirements, but for inter-island travel, a standard vet certificate is usually sufficient.
| Document Type | Required For | Validity | Notes |
| Health Certificate | All dogs | 10 days | Must be signed |
| Vaccination Record | All dogs | As per vaccination | Rabies, DHPP recommended |
| Service Dog Certification | Service dogs | Lifetime | Only if applicable |
| Microchip Info | All dogs | Lifetime | Not mandatory for inter-island |
Airport Check‑In Reality
Even with preparation, check-in can have surprises. Staff will measure carriers, weigh pets, and inspect documents.
Arriving early is key, as inter-island flights still enforce strict timing for pet handling. Some staff may have additional questions about breed, behavior, or temperature precautions.
| Check-In Item | Requirement | Potential Issue | Notes |
| Carrier Size | Must fit under seat | Oversized | Measure at home |
| Weight | Max 9 kg | Overweight dog | Weigh dog at home |
| Documentation | Health certificate | Missing or outdated | Keep multiple copies |
Denied Boarding Triggers
Denials usually occur due to oversized carriers, missing documentation, weight limits, breed restrictions, or exceeding cabin pet limits.
Being aware of these prevents unnecessary stress and ensures your dog’s travel is safe.
| Trigger | Description | Notes |
| Oversized Carrier | Exceeds allowed dimensions | Measure at home |
| Missing Docs | Health certificate missing | Keep multiple copies |
| Weight Exceeded | Dog + carrier >9 kg | Weigh dog in advance |
Route & Aircraft Variance
Certain inter-island routes or aircraft types may have stricter restrictions. For example, smaller planes may allow only one pet per cabin row, and some flights may restrict specific breeds during hot weather.
Always check your aircraft type when booking to avoid last-minute changes.
| Route | Max Pets Allowed | Breed Restrictions |
| Honolulu → Maui | 2 | Snub-nosed breeds limited |
| Honolulu → Kauai | 2 | Snub-nosed breeds limited |
| Honolulu → Big Island | 2 | Snub-nosed breeds limited |

Very strict. Carriers must meet exact airline dimensions. Even a slight oversize can result in denied boarding.
Can a dog fly if its carrier just barely fits under the seat?
Technically yes, but the dog must be comfortable. A cramped carrier may stress the dog and can be flagged at check-in if it doesn’t meet standards.

Hawaiian recommends at least 60–90 minutes for inter-island flights to allow for carrier inspection and documentation checks.
