Why Choosing the Right Airline Matters When Flying with a Pet from Saint Paul

Flying with a dog, cat, or other small animal from the Twin Cities region demands more than just a ticket. The airline you select can determine whether your pet travels in the cabin beside you, rides in the temperature‑controlled cargo hold, or stays home altogether. For pet owners departing from Minneapolis‑Saint Paul International Airport (MSP), a handful of carriers stand out for their consistent, compassionate pet policies. Yet even among these pet‑friendly airlines, the rules around carrier size, weight limits, breed restrictions, and seasonal embargoes vary noticeably.

Knowing which airlines prioritize animal welfare and which treat pets as an afterthought helps you avoid last‑minute stress at the gate. This guide breaks down the best airlines for pets traveling from Saint Paul, explains their specific requirements, and offers practical steps to get your companion ready for the journey.

Top Pet-Friendly Airlines Flying from Minneapolis‑Saint Paul International Airport

Several major airlines serve MSP with routes across the United States and abroad. The following carriers offer some form of pet travel, from in‑cabin carry‑on to checked baggage and specialized cargo programs. Not all are equally flexible, however—so you will need to match your pet’s size and temperament to the right option.

Alaska Airlines – Flexible Policies for Both Small and Large Pets

Alaska Airlines consistently ranks among the most pet‑accommodating airlines in the country. The carrier allows small dogs, cats, rabbits, and household birds to travel in the cabin if the combined weight of the pet and carrier stays under 20 pounds. Soft‑sided and hard‑sided carriers are both accepted as long as they fit under the seat in front of you.

For pets that exceed the cabin weight limit, Alaska Airlines permits them as checked baggage on most domestic flights. The airline’s climate‑controlled cargo compartments maintain safe temperatures, and staff follow careful handling protocols during loading and unloading. Large dogs, including breeds like Labrador Retrievers and Golden Retrievers, can travel this way as long as they are secured in a rigid, airline‑approved crate.

Alaska Airlines charges a pet fee of $100 each way for both in‑cabin and checked baggage transport. There is no cargo‑only pet program; instead, all animals travel as either carry‑on or checked luggage. The airline does enforce a few important restrictions. Snub‑nosed dog and cat breeds—such as Bulldogs, Pugs, Persian cats, and Himalayan cats—are not permitted in the cargo hold because of their increased risk of respiratory distress at altitude. They may still travel in the cabin if they meet the size requirements.

Advance reservations are mandatory, and a maximum of five pet carriers can be booked in the cabin on any given flight. If you are planning a trip that includes a connection, verify that both segments accommodate your pet, as some partner regional jets may have smaller under‑seat storage. You can read the full rules on the Alaska Airlines pet travel page.

Sun Country Airlines – Local Carrier with Affordable, No‑Frills Pet Options

Based in Minnesota, Sun Country Airlines operates a hub at MSP and understands the needs of local travelers. The airline permits small cats and dogs to fly in the cabin for a fee, typically lower than the legacy carriers. The maximum weight allowed is 20 pounds including the carrier, and the pet must remain inside a soft‑sided or hard‑sided carrier that fits beneath the seat.

Sun Country also accepts larger dogs as checked baggage, but the pet must be transported in a hard‑sided, leak‑proof crate that meets International Air Transport Association (IATA) standards. Unlike some competitors, Sun Country does not offer a separate pet cargo service; checked baggage is the only option for animals that cannot travel in the cabin. That makes the airline a reasonable choice for vacationers flying direct routes rather than those needing complex connections.

One advantage of Sun Country is that pet fees tend to be more budget‑friendly. Fare structures change frequently, so confirming the exact pet fee for your specific itinerary is essential. While the airline’s network is smaller than the big national carriers, its focus on non‑stop leisure destinations means you can often avoid stressful layovers. Book your pet’s spot early, as capacity for animals on each flight is limited. The most current fee schedule and crate dimensions are available on the Sun Country pets page.

Delta Air Lines – Cargo Program for Larger Dogs and International Flights

Delta Air Lines no longer accepts pets as checked baggage for domestic trips unless they are traveling through its Delta Cargo program. For passengers flying with pets from MSP, this means that only small dogs, cats, and household birds that can fit in an under‑seat carrier are allowed in the cabin. The combined weight limit is typically 20 pounds, and a fee of $125 each way applies for U.S. flights.

All larger animals must be shipped via Delta Cargo, a separate service that operates independently of passenger check‑in. The cargo facility at MSP is located away from the main terminal, so you will need to drop off your pet a few hours before both the passenger and cargo flight. Delta Cargo follows strict temperature and breed regulations, and it does not accept snub‑nosed animals at any time of year when temperatures fall outside a safe range. This service works well for military moves, international relocations, or situations where you are transporting a large dog on a route without a cabin alternative.

The cabin option through Delta remains popular among small‑pet owners in Saint Paul because the airline offers frequent flights to many domestic hubs. It is vital, however, to book your pet’s reservation as soon as you purchase your own ticket. Delta limits the number of pets per cabin, and popular routes can sold out weeks in advance. For complete rules, visit the Delta pet travel overview.

American Airlines – Structured Program with Seasonal Limits

American Airlines welcomes small cats and dogs in the cabin on most flights within the United States, as well as to and from select international destinations. The maximum size for cabin pets echoes the industry standard: pet and carrier together cannot exceed 20 pounds. The fee is $125 per kennel, each way.

Checked pet service through American is available on a route‑specific basis and only for active‑duty U.S. military and State Department personnel traveling on official orders. For everyone else, larger pets must be shipped as cargo, but American Airlines Cargo does not currently accept live animals for many origin‑destination pairs. This policy makes American a less versatile choice if you need to transport a medium‑sized or large dog from Saint Paul unless you are eligible for the military exception.

American also enforces seasonal embargoes on checked pets during summer and winter months, when extreme temperatures can pose a risk. Even in the cabin, brachycephalic (snub‑nosed) dogs and cats are permitted, but careful attention to carrier ventilation is required. Because policies shift periodically, reviewing the American Airlines pet travel page before booking is wise.

Comparing Airline Pet Policies at a Glance

The table below offers a side‑by‑side snapshot of key policies for major carriers serving Minneapolis‑Saint Paul International Airport. Use it as a starting point, then confirm details directly with the airline before you book.

Airline In-Cabin Pet Weight Limit Checked Baggage for Pets Cargo Service Typical Fee (Each Way) Key Restrictions
Alaska Airlines Under 20 lbs (pet + carrier) Yes No $100 No snub‑nosed breeds in cargo
Sun Country Airlines Under 20 lbs Yes, crated No Lower than most majors No cargo program; limited route network
Delta Air Lines Under 20 lbs No (except select international) Yes (Delta Cargo) $125 cabin; cargo varies No snub‑nosed breeds in cargo; separate drop‑off
American Airlines Under 20 lbs Military/State Dept. only Limited availability $125 Strict breed and seasonal embargoes

Each airline also places a cap on the number of animals per flight. Booking early—often alongside your own reservation—is the single most reliable way to secure a spot for your pet.

Understanding Pet Travel Regulations and Requirements

Beyond the airline’s own rules, government regulations and common‑sense safety standards shape what you must do before arriving at MSP with an animal. These requirements exist to protect both your pet and other passengers.

Carrier and Crate Size Guidelines

For cabin travel, every airline requires a carrier that fits completely under the seat. Soft‑sided carriers are popular because they can compress slightly to fit into tight spaces, but hard‑sided kennels are also accepted as long as they meet the airline’s height, width, and length limits. As a rule of thumb, carriers should not exceed 17.5 by 11 by 9 inches, though some airlines accept slightly larger dimensions on certain aircraft. Always look up the exact under‑seat dimensions for your flight model.

Your pet must be able to stand up, turn around, and lie down naturally inside the carrier without pressing against the sides or top. For checked baggage and cargo travel, the crate must be rigid, leak‑proof, and secured with metal bolts—not just snap closures. Crates should have ventilation on all four sides, and the door must be fastened with sturdy zip ties or similar closures. Airlines are strict about crate condition; a cracked or broken crate will be rejected at check‑in.

Health Certificates and Documentation for Domestic and International Travel

Within the United States, a Certificate of Veterinary Inspection (CVI), commonly called a health certificate, is often required when flying with a pet. Even if your chosen airline does not demand one, having a recent certificate issued by your veterinarian within 10 days of travel is a prudent safety net. It confirms your pet is free from contagious diseases and is fit to fly.

If you are traveling internationally from MSP, the requirements become more complex. Nearly every destination country demands a health certificate endorsed by the USDA‑APHIS within a specific timeframe, sometimes as little as 10 days before entry. Some countries also require proof of rabies vaccination, microchip implantation, or specific blood titer tests. Contact the destination country’s consulate or visit the USDA Pet Travel website for the latest import rules. For domestic flights, you may also need a CVI if you are entering a state with strict agricultural regulations, such as Hawaii.

Keep all paperwork easily accessible during check‑in and security screening. Airline agents may ask to see the health certificate, vaccination records, and your pet’s carrier tag with your contact information. It is also wise to carry a recent photo of your pet in case of an unforeseen separation.

Breed Restrictions and Temperature Embargoes

Most airlines prohibit snub‑nosed (brachycephalic) breeds of dogs and cats from traveling in the cargo hold because they are prone to overheating and breathing difficulties. Breeds like Boston Terriers, Boxers, Shih Tzus, and Persian cats are typically limited to cabin travel only, and even then during temperate months. Airlines may also ban other strong‑jawed breeds such as American Pit Bull Terriers from cargo service.

Temperature embargoes are another common rule. During summer, when ground temperatures at a connection point exceed 85 degrees Fahrenheit, airlines may refuse to load pets. In winter, when temperatures drop below 20 degrees Fahrenheit, similar embargoes take effect. If your itinerary includes a layover, check the weather along the entire route. Some carriers offer climate‑controlled cargo vehicles and holding areas, but restrictions still apply.

MSP International Airport Facilities for Traveling Pets

Minneapolis‑Saint Paul International Airport has invested in making the travel experience easier for pets and their owners. Knowing where to find pet relief areas and how to manage security screening can help your animal stay calm before boarding.

Pet Relief Areas and Post‑Security Options

MSP provides designated pet relief areas outside both Terminal 1 and Terminal 2. These grassy, fenced spaces are located on the arrivals level and are accessible before you pass through security. They give dogs a chance to relieve themselves and burn off a little energy after the drive to the airport.

Once you are past security, options become more limited. Currently, MSP does not have indoor post‑security pet relief stations like some larger airports. If you have a long layover, you may need to exit the secure area, visit the outdoor relief zone, and re‑enter through TSA screening—a process that requires extra time. Always factor in at least 45 minutes for a post‑security potty break when planning your arrival.

You can confirm the exact locations of pet relief areas by visiting the MSP Airport pet relief page or by asking a Travelers Assistance volunteer once you arrive.

Tips for a Smooth Check‑In with Your Pet

Arrive at the airport at least two hours before a domestic flight and three hours before an international departure when traveling with an animal. A longer cushion gives you time to deal with paperwork, crate inspection, and the unexpected. Have your pet’s carrier fully assembled and ready for inspection. Attach a laminated card to the outside of the carrier showing your name, phone number, flight number, and destination.

At the check‑in counter, you will present your pet, the carrier, and the health documents. The agent may weigh the carrier or ask to see that your pet can stand and turn inside. Be patient and let your pet remain as calm as possible. After check‑in, you will need to pass through TSA security. You will be instructed to remove your pet from the carrier and carry it through the metal detector while the empty carrier goes through the X‑ray machine. A retractable leash and a calm demeanor help here.

Practical Advice for a Safe and Stress‑Free Flight with Your Pet

A successful trip starts days—or even weeks—before you ever set foot in MSP. Conditioning your pet to the carrier, planning meals around the flight schedule, and making smart seat selections all contribute to a smooth experience.

Acclimating Your Pet to the Carrier

Spend several weeks before travel familiarizing your pet with the carrier. Leave it open in your living area with a soft blanket and a few treats inside. Encourage your dog or cat to enter voluntarily, and reward them calmly. Slowly increase the time they spend inside with the door closed, working up to an hour or more if possible.

For cats, placing a worn t‑shirt that carries your scent inside the carrier can reduce anxiety. For dogs, taking short car rides in the carrier helps them associate the enclosure with motion and routine. Do not wait until the day of travel to introduce the carrier for the first time; a rushed introduction often backfires and leads to vocal, stressed animals on the plane.

Feeding, Hydration, and Comfort Strategies

Feed your pet a light meal about three to four hours before your flight. Avoid heavy, rich foods that could upset their stomach. Limiting water in the hour before boarding reduces the likelihood of an accident inside the carrier, but never withhold water entirely—your pet should be well hydrated before you leave home. Freeze a small gel pack or use a clip‑on bowl that attaches to the carrier door for longer trips, filling it only when you are safely through security.

Pack a leash, waste bags, and a collapsible water dish in your personal bag. If you are traveling with a dog, a quick pre‑boarding walk outside the terminal can make a big difference. For cats, lining the carrier with an absorbent pad gives you a safety net if they cannot hold it until arrival. A familiar toy or blanket tucked inside can also provide emotional comfort without taking up valuable space.

Booking and Seat Selection Tactics

When you book your flight, notify the airline immediately that you plan to bring a pet. Seat selection matters—bulkhead rows often have fixed armrests and no under‑seat storage, making them useless for a pet carrier. Instead, choose a window seat in a row where the carrier will slide under the seat in front of you. Middle and aisle seats generally work as well, but a window seat gives you more control over your pet’s exposure to foot traffic.

Try to book non‑stop routes whenever possible. Each connection adds handling, temperature changes, and the possibility of a missed flight. If a layover is unavoidable, make the connection long enough that you can exit and use the pet relief area. Two hours is a safe buffer for a domestic layover.

Check the airline’s pet policy again 24 hours before departure. Weather‑related embargoes or equipment changes can suddenly affect pet acceptance, and an early re‑check helps you pivot if needed.

Answers to Common Questions about Flying with a Pet from Saint Paul

Can my large dog fly in the cabin with me from MSP?

Generally, no. In‑cabin pets must remain in a carrier that fits under the seat, and the combined weight cannot exceed 20 pounds. Most large and even many medium‑sized dogs exceed this limit. For them, options include checked baggage (on Alaska Airlines and Sun Country) or cargo shipping through Delta Cargo, depending on the route and breed.

What if my pet is an emotional support animal?

Regulations changed significantly in recent years. Most U.S. airlines no longer recognize emotional support animals as free‑of‑charge cabin companions. Instead, they are treated as pets and must meet all pet travel requirements, including carrier size and fee payment. Service animals, trained to perform tasks for a person with a disability, are still accommodated free of charge, but documentation rules have tightened. Verify the airline’s current service animal policy before you book.

Are there any pet shipping services that handle everything?

Yes. If the logistics feel overwhelming, professional pet relocation services can arrange door‑to‑door transport, handle all paperwork, and coordinate with cargo departments. These companies are especially useful for international moves. Research their reputation carefully and confirm that they follow IATA live animal transport standards.

How early should I arrive at MSP when flying with a pet?

Aim for a full two hours before a domestic flight and three hours before an international one. The extra time covers potential delays at check‑in, crate inspection, and TSA screening with your pet outside the carrier. Security lines at MSP can be long during peak morning and holiday periods, and you never want to feel rushed with an anxious animal.

What happens if my flight is delayed or canceled?

Airline staff will work to accommodate you on a later flight, but re‑accommodating a pet is not always guaranteed if the new flight’s pet capacity is already full. In the event of a lengthy delay or overnight cancellation, the airline should assist you in finding a pet‑friendly hotel or alternate arrangements. Carry enough food, water, and waste supplies in your carry‑on to cover at least 24 hours, just in case.

Every trip with a pet from Saint Paul begins with a careful choice of airline and thoughtful preparation. By matching your animal’s size, breed, and temperament to the right carrier program and by arriving at MSP with complete paperwork and a calm mindset, you set the stage for a flight that is as comfortable for you as it is for your four‑legged companion.
