Pet owners often face the challenge of finding an airline that not only allows pet travel but also ensures comfort and safety throughout the journey. Whether you're relocating, vacationing, or traveling for business, understanding how to book a pet on United Airlines can be a game changer for pet parents.
Let’s explore the complete process step-by-step from booking to boarding so you can confidently travel with your pet on United.
United Airlines offers pet travel through two primary services: In-Cabin Pet Travel and PetSafe (Cargo Travel). Each comes with its own set of guidelines, fees, and restrictions.
If your pet is small enough to fit in an airline-approved carrier that fits under the seat in front of you, they can travel in-cabin. Here are the key requirements:
Eligible Animals: Dogs and cats
Age Requirement: Pets must be at least 2 months old (for domestic travel) and 4 months old (for international flights)
Carrier Dimensions: Soft-sided carrier not exceeding 18" x 11" x 11"
Fee: $125 each way
Flights Allowed: Domestic and select international flights
Note: Only one pet is allowed per passenger in the cabin. Advance reservations are strongly recommended due to limited space.
For pets that cannot travel in the cabin due to size or breed, United offers the PetSafe program, which is designed for animal safety and comfort:
Available for: Dogs, cats, rabbits, and some other domesticated animals
Temperature-Controlled Compartments
Trained PetSafe Handlers
Tracking and Customer Notification System
Cost: Based on weight and destination (typically starts around $200 and up)
The PetSafe program has seasonal restrictions and limited breed acceptance, especially for brachycephalic (snub-nosed) breeds.
Whether your pet is flying in-cabin or in the cargo hold, it’s crucial to book early and follow the correct procedures. Here’s how:
Visit United Airlines’ official pet travel page to confirm your pet qualifies for travel. Consider size, age, health, and breed restrictions. If you're unsure, call customer service at +1-833-654-7126 or +1 888-80-31-162 for clarification.
Start by booking your own flight. You can book online via United's official website, app, or by calling their flight booking helpline. Always ensure that the aircraft and route you select allows pet travel.
Tip: Avoid layovers and multiple stops to reduce stress for your pet.
Once your ticket is confirmed:
For In-Cabin Pets: Call United customer service immediately after booking your flight to reserve space for your pet. Spots are limited and first-come, first-served.
For PetSafe Cargo: Book through the PetSafe desk (accessible via United’s website or by calling customer service). They’ll guide you through required documents, drop-off procedures, and crate specifications.
Most bookings require:
Health Certificate (Issued within 10 days of travel)
Vaccination Records
Import Permits (for international travel)
Pet ID Tags and Microchip (highly recommended)
Check destination-specific regulations, especially for international flights.
For in-cabin pets, soft-sided, leak-proof carriers with proper ventilation are required. For PetSafe cargo, purchase a USDA-approved crate with food and water bowls attached inside.
Even after booking, preparation is key to a smooth journey. These expert-backed tips will ensure your pet remains calm, safe, and comfortable.
Let your pet explore and rest in the carrier several days before the flight. This reduces stress during actual travel.
Avoid feeding your pet 2–4 hours before the flight. A light meal a few hours before departure is generally sufficient.
Attach a label with your contact info, pet’s name, and any special instructions for handlers.
Let your pet relieve themselves and get light exercise before arriving at the airport.
United Airlines has specific breed and route limitations for both in-cabin and cargo pet travel.
Brachycephalic Dogs and Cats (e.g., Pugs, Bulldogs, Persian Cats) may be banned from cargo travel due to respiratory risks.
Some breeds may not be allowed in-cabin due to temperament or size.
Not all international destinations allow pet travel.
Certain countries like Australia, New Zealand, UAE, and South Africa have strict quarantine laws.
Extreme temperatures may cause seasonal route suspensions for PetSafe services.
Always confirm with United or call +1-833-654-7126 / +1 888-80-31-162 for destination-specific restrictions.
No, United only allows one pet per passenger in the cabin.
In-cabin pets: $125 one-way.
PetSafe cargo: Price varies based on weight and distance (typically $200+).
As of 2021, United no longer recognizes ESAs. Only trained service animals are permitted to fly without a carrier and free of charge.
Only human flights can be booked online. You must call United directly to reserve space for your pet.

While this article focuses on United Airlines, many travelers compare pet travel options across airlines, including Delta Airlines.
United Airlines excels in cargo pet care with its PetSafe program, while Delta offers more extensive international options in some cases. Depending on your destination and pet size, compare both before making a flight booking.
Flying with a pet doesn’t have to be stressful. United Airlines provides reliable options for both in-cabin and cargo pet travel, with clear policies, transparent pricing, and trained staff.
Before booking, carefully evaluate:
Your pet’s size, health, and breed
The route and aircraft used
Seasonal and destination-based restrictions
Carrier/crate requirements and documentation
Booking your pet’s flight early, preparing the required paperwork, and understanding United’s pet policy are critical steps in ensuring a successful travel experience.
