Important Notes:

- Service dogs travel free but require advance notification and documentation.
- PetSafe fees are estimates; actual cost depends on crate dimensions and total weight.
- Hawaii has strict import requirements—pets may face quarantine if not compliant.
Hawaii Quarantine Warning
Hawaii is a rabies-free state with strict import requirements. Pets may face 5-day or 120-day quarantine if pre-arrival requirements are not met (rabies titer test, waiting periods, health certificates). Always verify Hawaii Department of Agriculture requirements before booking.
🎒 Carrier & Crate Requirements
Using a non-compliant carrier is the leading cause of denied boarding. United strictly enforces these dimensions.

⚠️ Breed Restrictions & Embargoes
United Airlines restricts certain breeds for safety reasons, particularly in PetSafe cargo.
Brachycephalic (Short-Nosed) Breeds
PetSafe Restriction: United PetSafe does not accept brachycephalic dog and cat breeds (e.g., Bulldogs, Pugs, Boxers, Persian cats) due to respiratory risks.
In-Cabin Exception: These breeds may be accepted in the cabin if they meet the weight/size limits, but advance approval is recommended. Always contact United Reservations before booking.
Temperature Embargoes
Seasonal Embargo: United enforces temperature embargoes if origin/destination temperatures exceed safe limits (typically <7°C / 45°F or >30°C / 86°F). This is common in summer (June–August) and winter (December–February).
Solution: Book early morning or late evening flights; avoid peak summer/winter travel.
📋 How to Book Pet Travel on United Airlines
You cannot book pet travel entirely online. Follow this sequence to secure space.
Step 1: Check Eligibility (Before Booking Flight)
- Weigh your pet + carrier. If ≤9kg and fits 46x28x28cm, in-cabin is possible.
- Verify breed restrictions (especially for short-nosed breeds).
- Check destination country/state import rules (health cert, microchip, quarantine).
Step 2: Contact United Reservations
- Call United Reservations: 1-800-UNITED-1 (1-800-864-8331).
- Request pet space availability for your desired flight.
- Note: Only a limited number of pets are allowed per flight (typically 4-6 in cabin).
Step 3: Book Human Ticket & Add Pet
- Once pet space is confirmed verbally, book your human ticket.
- Pay the pet fee immediately over the phone.
- Ensure the pet reservation is linked to your booking reference (confirmation number).
Step 4: Prepare Documents (10 Days Before)
- Obtain health certificate for international travel (within 10 days of travel).
- Ensure microchip is ISO compliant and scanned correctly.
- For Hawaii: Complete pre-arrival requirements to avoid quarantine.

Step 5: Check-In (Day Of)
