Can I purchase a seat for my dog to sit next to me on a U.S. airline?

No, nearly all U.S. airlines require small dogs to remain in approved carriers under the seat in front of you. United Airlines only allows purchasing a second seat for a second pet and both must stay under adjacent seats.

What are the pet carrier size limits for in-cabin airline travel?

Carriers generally must fit under standard airline seats, typically up to 18"L x 11"W x 11"H. Specific limits vary by airline, so always check ahead before flying.

How much does it cost to bring a small dog in the cabin?

Fees range from $50 to $150 per direction, depending on carrier and route. The cost is paid separately from your own ticket.

Can my small dog sit on my lap during the flight?

No. For safety your dog must remain inside their closed carrier under the seat at all times. Lap-sitting is not permitted during any phase of flight.

What are the best airline approved carriers for dogs?

Top-rated choices include Sherpa Deluxe, Sleepypod Air, Roverlund Out of Office, and Mr. Peanut’s Gold Series Expandable. Quality, fit, ventilation, and comfort are the main factors.

What travel documents does my dog need for flying?

Most domestic flights only need proof of age and up-to-date vaccinations. International flights usually require a vet-issued health certificate no older than 10 days and may need other documentation depending on your destination.

Can I Buy a Seat for My Small Dog on a Plane? The Facts

Many dog parents ask if it’s possible to purchase a dedicated seat for their small dog on a plane. While traveling with pets is more popular than ever, airlines have strict rules that impact your options. Here’s what you really need to know about airline pet seating policies in the U.S., including exceptions, alternatives, and practical advice for a seamless journey.

US Airline Policies: Purchasing a Seat for Your Dog

Most major U.S. airlines do not allow you to buy a separate seat for your small dog. Instead, regulations require that dogs must stay in an approved carrier under the seat in front of you. This applies to nearly all cabin pet policies on airlines such as Delta, American Airlines, Alaska, United, Southwest, JetBlue, and Spirit [Chewy Guide].

There is a rare exception: United Airlines permits booking a second seat only if you are traveling with two pets, with each pet in a separate carrier. Both carriers must fit under adjacent seats. That’s not the same as having your dog ride on the seat beside you; your pet still needs to stay in their carrier at all times [United Pet Policy].

Some international airlines like Aeroflot, and select business/private charter operators, might allow more flexible arrangements. But for travel on U.S. carriers, the under-seat carrier policy is nearly universal [Travelnuity].

Why Not on the Seat?

The primary reasons are safety and compliance with FAA regulations. During taxi, takeoff, landing, and turbulence, pets must remain secured in approved carriers under the seat. This minimizes risk to both the animal and other passengers.

Key Rules for Dogs Traveling In-Cabin

Carrier Fit: Carrier must fit under the seat in front of you; average dimensions are around 18"L x 11"W x 11"H (confirm with your airline).
Weight Limits: Total weight (dog plus carrier) usually must be under 15–20 lbs (7–9 kg).
Pet Age & Health: Minimum age is typically 8 weeks (domestic) and 16 weeks (international); dogs must be healthy and up-to-date on vaccinations.
Carrier Type: Only FAA-approved hard or soft-sided carriers allowed.
Seating: No pets in emergency exit rows or bulkhead seats; no overhead bin travel for pets.
Fees: Most airlines charge $50–$150 each way per pet in-cabin.

How to Travel Safely and Comfortably with Your Small Dog

Choose the Right Carrier: Opt for airline-approved carriers that offer ventilation, security, and comfort. Get your dog accustomed to the carrier at home before traveling.
Reserve Early: Airlines limit the total number of pets per flight, so book as soon as possible and always call to confirm your spot.
Pack Essentials: Bring water, collapsible bowl, treats, a familiar toy, potty pads, and lining for the carrier. Use a waterproof and organized dog walking bag like the Red Rover Bag for all essentials.
Check Documents: Domestic and international flights may require health certificates and proof of vaccinations. Visit your vet in advance and carry hard copies of all paperwork [US Dept. of State].

Keep an eye on your dog’s comfort: Offer drops of water, check for overheating or chills, and soothe with soft words or familiar items.
