Traveling with a pet can be one of the most rewarding experiences — or one of the most stressful, if you're not prepared. Whether you're hopping on a plane, hitting the road, or taking a weekend trip, having the right carrier and knowing the rules can make all the difference.
This guide covers everything you need to know about traveling with your dog or cat, including airline regulations, carrier types, and our top product picks.
Airline Pet Travel: The Basics
Before you book, check your airline's specific pet policy — rules vary by carrier. Here are the general guidelines most airlines follow:
- In-cabin pets: Most airlines allow small dogs and cats in the cabin if they fit in an approved carrier under the seat in front of you
- Size limits: Typically your pet + carrier must weigh under 20 lbs combined
- Carrier dimensions: Usually around 18" x 11" x 11" — always check your specific airline
- Health certificate: Many airlines require a vet-issued health certificate dated within 10 days of travel
- Fees: Expect a pet fee of $95–$150 each way on most U.S. airlines
- Booking early: Airlines limit the number of pets per flight — book your pet's spot as soon as possible
Choosing the Right Pet Carrier
Airline-Approved Soft-Sided Carriers
The most versatile option for air travel. Soft sides compress slightly to fit under the seat, and mesh panels provide ventilation. Look for carriers with top and side entry, interior padding, and a secure zipper system.
Our Airline Approved Soft Sided Pet Carrier fits pets up to 20 lbs and meets most major airline requirements. It features breathable mesh on three sides, a padded interior, and a top-loading design for easy access.
Airline-Compliant Backpack Carriers
Backpack-style carriers are ideal for hands-free travel through airports. The Mr. Peanut's Monterey Series Airline Compliant Backpack Carrier is designed to meet airline under-seat dimensions while giving you the comfort of a backpack. Perfect for navigating busy terminals.
Soft-Sided Tote & Shoulder Carriers
For shorter trips or ground travel, a breathable tote-style carrier offers easy access and portability. The Portable Mesh Breathable Carrier Bag is foldable, lightweight, and works great for vet visits, car rides, and day trips.
Collapsible Travel Carriers
The Collapsible Soft-Sided Travel Carrier is a great all-rounder — it holds pets up to 15 lbs, folds flat for storage, and has multiple entry points for easy loading.
Road Trip Tips for Pet Travel
- Never let pets roam freely in the car — use a carrier or crash-tested harness
- Take breaks every 2–3 hours for water, bathroom, and stretching
- Keep the car cool — never leave pets in a parked car, even briefly
- Bring familiar items — a favorite blanket or toy reduces anxiety
- Feed lightly before travel to reduce motion sickness risk
- ID your pet — make sure tags and microchip info are current before any trip
Helping Your Pet Adjust to Their Carrier
Don't wait until travel day to introduce the carrier. Start weeks in advance:
- Place the carrier in a common area with the door open
- Put treats and familiar bedding inside to create positive associations
- Feed meals near or inside the carrier
- Practice short trips in the car before longer journeys
- Use calming sprays or pheromone products if your pet is anxious
What to Pack for Pet Travel
- Collapsible water bowl and bottled water
- Enough food for the trip plus extra
- Waste bags and a portable litter box for cats
- Vet records and health certificate
- Any medications your pet takes
- A familiar toy or blanket
- Pet first aid kit
