Check Your Free Pet Travel Eligibility
When it comes to Pet travel is the practice of moving companion animals by air, sea, or land, with a focus on airline journeys, the first question most owners ask is whether they can do it without paying extra. The short answer is: only a handful of airlines let you bring a pet on board for free, and even then the rules are tight. Below you’ll find the exact criteria, the airlines that currently offer a free option, and the hidden costs you might still face.
Key Takeaways
- Only a few carriers in the world allow free pet travel for in‑cabin pets, typically on short domestic routes.
- Eligibility usually depends on pet size, weight, and carrier dimensions.
- Even when a fee is waived, you still need a health certificate, pet passport, and an approved carrier.
- Most airlines charge a fee for cargo‑only transport, which can range from $50 to $500 per segment.
- Booking early and confirming the policy directly with the airline are essential to avoid surprises.
How Airlines Decide What’s Free
Airlines treat pets as either In‑Cabin pet is a small animal that travels with the owner inside the passenger cabin, stored in an approved carrier under the seat or as cargo. The decision to waive the fee often hinges on three main factors:
- Weight and size limits: Most free‑pet policies cap the combined weight of pet and carrier at 8kg (about 18lb). Anything heavier moves to the cargo hold, where fees apply.
- Route length: Short‑haul flights (usually under three hours) are more likely to allow a free in‑cabin pet because the cabin space impact is minimal.
- Airline brand strategy: Some carriers use free pet travel as a loyalty perk for frequent flyers or for routes with low demand.
Airlines That Currently Offer Free In‑Cabin Pet Travel
Airline | Free In‑Cabin Pet? | Max Pet+Carrier Weight | Typical Route Restrictions |
---|---|---|---|
Air New Zealand is the flag carrier of New Zealand, known for its “Kiwi Buddy” program | Yes (on select domestic routes) | 8kg | Domestic flights between Auckland, Wellington, Christchurch |
Qantas is Australia’s largest airline, operating an extensive domestic network | Yes (on a few short hauls) | 7kg | Flights under 2h, e.g., Sydney‑Melbourne |
United Airlines is a major US carrier that occasionally waives pet fees for elite members | Yes (for MileagePlus Premier members on select routes) | 8kg | Domestic coast‑to‑coast flights under 4h |
Southwest Airlines is U.S. low‑cost carrier with a “Pet Policy” that sometimes excludes fees for very small pets | Yes (on most domestic routes) | 6kg | All domestic flights, provided the carrier fits under the seat |
Other carriers | No | N/A | N/A |

Hidden Costs Even When the Ticket Is Free
A “free” pet journey rarely means you walk away with zero expense. Here’s what you’ll still need to budget for:
- Approved carrier: Most airlines require a hard‑sided carrier that meets specific dimensions (usually no larger than 45×35×20cm). Prices range from $20 to $80.
- Health certificate: A vet must sign a certificate within 10days of travel. In NewZealand this costs about NZ$60; in the U.S. it’s roughly $50-$100.
- Pet passport or import permit: International trips need a passport (EU) or an import permit (Australia, NewZealand). Expect $45-$150.
- Airport handling fee: Some airports levy a small service charge, typically $5-$15 per pet.
Step‑by‑Step Guide to Booking a Free Pet Spot
- Check the airline’s official pet policy page. Look for phrases like “no fee” or “free in‑cabin pet.”
- Confirm the route you plan to travel meets the length and weight limits.
- Call the airline’s reservations center (do not rely solely on online booking) and ask to reserve a pet spot. Mention you qualify for the free option.
- Purchase an approved carrier that meets the airline’s size specifications.
- Arrange a pre‑flight health check with your vet and obtain the required certificate.
- Arrive at the airport at least two hours early (three for international) to complete the paperwork.
- Place the carrier under the seat in front of you before take‑off and keep the pet calm with a familiar blanket.
Common Pitfalls and How to Avoid Them
Even seasoned travelers stumble over a few details:
- Assuming “free” means “no paperwork.” You still need all the documentation the airline requires.
- Booking a seat that doesn’t have under‑seat space. Some rows (emergency exit, bulkhead) prohibit pets.
- Waiting until the last minute. Free pet spots are limited and can fill up fast, especially on popular routes.
- Using a soft‑sided carrier when the airline mandates hard‑sided. The flight could be delayed while staff find a suitable container.
- Ignoring breed restrictions. Some airlines ban brachycephalic breeds (e.g., Pugs, French Bulldogs) for safety reasons.

Alternatives When Free Travel Isn’t Available
If your airline of choice doesn’t waive the fee, consider these options:
- Use a pet‑friendly airline that offers lower fees. Many regional carriers charge as little as $30 for in‑cabin pets.
- Ship your pet as cargo with a reputable service. Companies like PetRelocation is a global pet‑transport specialist that handles door‑to‑door moves can negotiate bulk discounts for frequent travelers.
- Drive to your destination. For short distances, a road trip eliminates airline restrictions altogether.
- Consider a pet‑sitting service. If the journey is lengthy, a professional sitter at the destination may be less stressful for the animal.
What the Future Holds for Free Pet Travel
Industry analysts predict that as pet ownership rises-especially among Millennials and GenZ-the pressure on airlines to make pet travel more affordable will increase. By 2027, we may see more carriers introducing “pet‑free‑fare” promotions during low‑season periods, much like they already do for unaccompanied minors.
