If you’ve started researching how to get your dog or cat on a plane, you’ve probably noticed the same three terms keep coming up: in-cabin, excess baggage, and cargo. They sound like three menu options, as if you could just pick your favorite the way you’d pick a seat assignment.
In practice, it rarely works that way. The airline, the destination country, your pet’s size, and even the breed all have a vote before you do. Here’s what each option actually involves, and how to figure out which one your pet parent journey will land on.
1. In-Cabin: Your Pet Rides With You
This is the option every pet parent hopes for. Your pet stays close, you can see the carrier at your feet, and there’s no separate check-in process to manage.
What it actually requires:
- Your pet (and the carrier) must fit under the seat in front of you. Airlines set exact dimensions, and they vary by aircraft, not just by airline.
- Pets typically need to stay zipped in the carrier for the entire flight, no exceptions for a quick peek.
- Most airlines cap in-cabin pet travel at a combined pet-and-carrier weight, often somewhere around 20 pounds, though this varies.
- Your pet’s carrier usually counts as your one carry-on or personal item, so pack accordingly.
Where it falls apart: Many destination countries simply don’t allow pets to enter as in-cabin passengers, regardless of what the airline permits. The airline can say yes and the country can still say no, and the country’s rule wins every time. Brachycephalic (flat-faced) breeds, like French Bulldogs and Persian cats, are also increasingly restricted from cabin travel by airline policy due to breathing-related risk at altitude.
Please note: WorldCare Pet does not coordinate or advise on in-cabin pet travel arrangements. Pet parents are responsible for confirming in-cabin options directly with their airline. Our services focus exclusively on door-to-door international pet transport, including air cargo logistics and handling.
2. Excess or Accompanied Baggage: Checked Like Luggage, Held Like Cargo
Excess baggage refers to a pet that travels on the same passenger itinerary and is checked in through the passenger counter rather than as a standalone cargo shipment. The pet still rides in the aircraft’s cargo hold, but goes through the same check-in process as your luggage, as long as you’re booked on the same flight.
What it actually requires:
- An IATA-compliant kennel, sized so your pet can stand, turn around, and lie down naturally inside it.
- You and your pet must travel on the same flight; this is what separates “accompanied” baggage from manifest cargo.
- Temperature and pressurization in the hold are regulated, but many airlines pause hold travel during extreme heat or cold, called seasonal embargoes.
Where it falls apart: Fewer and fewer major carriers still offer this service, and the ones that do often restrict it by route, season, or breed. It’s worth confirming availability before you build a moving plan around it, since policies shift from year to year.
3. Manifest Cargo: The Option With the Fewest Restrictions
Cargo is the most misunderstood of the three, mostly because the word sounds cold. In reality, it’s often the safest and most consistent way for a pet to fly, especially over long distances or international borders.
What it actually requires:
- Check-in and pickup happen at the airline’s cargo terminal, not the passenger terminal, which means a separate stop, either for you or for whoever is coordinating the move on your behalf.
- Pets travel in the same pressurized, climate-controlled hold as accompanied baggage, just without you on the same flight.
- Many airlines only accept live-animal cargo bookings from certified pet shipping agents, not directly from individual travelers.
Where it works in your favor: Cargo isn’t tied to your personal itinerary. Your pet’s kennel can be sized for their actual comfort rather than an under-seat limit, and pretty much any pet, from a Chihuahua to a Great Dane, can travel this way.
So Which One Applies to Your Pet’s Move?
Here’s the honest answer: it depends on a combination of factors stacking on top of each other, and most pet parents don’t find out which one applies until they’re deep into planning.
- Destination country rules almost always override airline preference. Some countries, including the UK and Australia, require pets to arrive as manifest cargo, full stop, regardless of what the airline’s general pet policy says.
- Breed can eliminate cabin and sometimes baggage options entirely, particularly for brachycephalic breeds.
- Size determines whether in-cabin is even on the table. A 70-pound dog would never be able to go under that seat.
- Airline-specific policy changes constantly. Some carriers have paused accepting pets as cargo altogether in recent years, while others have expanded which breeds and routes they’ll accept.
You also need to take into consideration a possible layover, a second airline, or an international border. This is the exact problem an international pet relocation specialist solves: cross-referencing airline policy against destination requirements so you’re not the one untangling it flight by flight.
The Real Question Isn’t “Which Way Is Best”
It’s “which ways are actually available for my pet, on this route, to this country, this season.” For some moves, all three options are technically on the table. For others, cargo is the only option, and that’s not a downgrade, it’s just the rule for that destination.

Frequently Asked Questions
Can I choose how my pet flies? Not entirely. Airline policy and destination country requirements both have to align before an option becomes available, and country rules typically take priority.
Is cargo less safe than in-cabin travel? No. Pets flying as manifest cargo travel in the same pressurized, temperature-controlled hold as the passenger cabin.
Why do some countries require cargo only? Countries that require manifest cargo, like the UK and Australia, generally do so for biosecurity and customs processing reasons, since cargo shipments go through a more formal inspection and documentation chain.
Does my pet’s breed affect which option is available? Yes. Brachycephalic breeds face the most restrictions and are frequently excluded from in-cabin and sometimes baggage travel due to airline health and safety policy.
