How to Fly with a Dog or Cat on Major Airlines

Flying with a pet doesn’t have to be stressful — but it does require planning and knowing what each airline expects. Whether you’re taking a small dog in-cabin or transporting a larger pet as cargo, this guide breaks down how to fly with a dog or cat on major airlines.

Is Your Pet Eligible to Fly?

Before you book a ticket, make sure your pet qualifies to fly:

- Most airlines allow dogs and cats only — exotic pets, rabbits, and rodents are often excluded
- In-cabin pets typically must weigh under 20 pounds (including the carrier)
- Pets must be at least 8–10 weeks old, depending on the airline
- Some breeds, like brachycephalic (short-nosed) dogs and cats, may be restricted due to health risks

Always check your airline’s breed restrictions, age requirements, and health certificate rules before you book.

In-Cabin vs Cargo: What’s the Difference?

There are two main ways to fly with pets:

In-Cabin:
- Your pet stays in a soft-sided carrier under the seat in front of you
- Usually allowed only for small dogs and cats
- Airlines charge a fee per segment, typically $95–$125 each way
- You’re responsible for your pet’s behavior during the flight

Cargo (or “Checked Pet”):
- Your pet travels in the temperature-controlled cargo hold in a hard-shell crate
- Best for larger pets or certain international routes
- Requires additional planning, paperwork, and early check-in
- Cargo transport may be suspended during extreme temperatures or busy travel seasons

Airline Rules and Fees You Need to Know

Each airline has its own pet policy. Here are the basics for popular U.S. carriers:

- Delta: In-cabin only for pets under 20 lbs. Fee is $95–$125 per direction. No cargo option currently for pets.
- United: In-cabin pets allowed. Cargo service (PetSafe) suspended indefinitely.
- American Airlines: In-cabin and cargo (with restrictions). Fee is $125 in-cabin, $200 cargo.
- Alaska Airlines: One of the most pet-friendly. $100 per in-cabin pet.
- Southwest Airlines: In-cabin only, $95 fee. No cargo service.

International flights often have stricter rules. Always call the airline before booking to confirm policies, availability, and carrier dimensions.

Preparing Your Pet for the Flight

Once your flight is booked, it’s time to get your pet ready:

- Visit the vet for a check-up and required paperwork (including health certificate if flying cargo or internationally)
- Purchase an airline-approved carrier. Check exact dimensions required by your airline
- Get your pet used to the carrier before the flight with short trial sessions
- Avoid feeding your pet 4 to 6 hours before takeoff to reduce the chance of motion sickness
- Include absorbent pads, a familiar blanket, and ID tags inside the carrier

Some pet parents use calming sprays, treats, or vet-approved sedatives — consult your vet first.

Best Practices for Travel Day

To make the flight go smoothly:

- Arrive early — cargo pets usually need to check in at least 3 hours before departure
- Carry extra food, a collapsible water bowl, waste bags, and paperwork
- Walk your dog before entering the terminal
- Keep your pet in the carrier at all times in the airport and on the plane
- Be polite and calm at check-in — airline staff appreciate well-prepared passengers

Don’t forget to ask where the pet relief areas are located at both your departure and arrival airports.
