Traveling with your beloved pet from Memphis, Tennessee, can feel overwhelming, but choosing the right airline makes all the difference. Some carriers have earned a reputation for genuine animal care, while others have strict rules that leave little room for comfort. Alaska Airlines and Frontier Airlines consistently rank as favorites among Memphis pet owners because of their flexible policies, transparent fees, and thoughtful in-flight and ground services. This guide breaks down the best options, detailed requirements, and practical tips to ensure your furry companion enjoys a safe, comfortable journey—whether they ride in the cabin or fly in the cargo hold.

Top Pet-Friendly Airlines Departing Memphis

Memphis International Airport (MEM) connects you to multiple airlines with varying pet policies. Understanding each carrier’s stance on in-cabin travel, cargo handling, and fees will help you make an informed decision. The following airlines stand out for their commitment to safety and service.

Alaska Airlines: Cabin Comfort and Cargo Care

Alaska Airlines allows small pets in the cabin for a fee of $100 each way. Pets must remain in an approved carrier that fits under the seat, with maximum dimensions of 17" x 11" x 9.5" for soft-sided kennels or 17" x 11" x 7.5" for hard-sided ones. The combined weight of pet and carrier cannot exceed 20 pounds. Larger pets travel via Alaska’s Pet Cargo service, which operates out of temperature-controlled holds. Alaska is known for its attentive ground staff and clear communication during delays.

A unique perk: Alaska Mileage Plan members can earn miles for pet travel when the pet flies as cargo. The airline also offers a comprehensive pet travel page with checklists and seasonal embargoes to avoid. Before booking, confirm that your route from Memphis accepts pets—severe summer or winter temperatures may trigger embargoes for cargo pets.

Frontier Airlines: Budget-Friendly with Clear Rules

Frontier stands out for its straightforward, low-cost approach to pet travel. For $99 each way, you can bring a small dog, cat, rabbit, guinea pig, hamster, or small household bird in the cabin. The carrier must not exceed 18" x 14" x 8" and the pet must remain fully inside during the flight. Frontier does not transport pets as checked baggage or cargo—only in-cabin. This restriction means you cannot bring a larger animal, but it also eliminates the risks associated with cargo holds.

From Memphis, Frontier offers nonstop and connecting routes, and the airline’s simple fee structure avoids unexpected charges. The Frontier pet policy page lists all accepted species and size limits, making it easy to prepare. Early booking is recommended because each flight permits a limited number of pets.

Delta Air Lines: Solid Options for Small Pets

Delta accepts small dogs, cats, and household birds in the cabin on most domestic flights from Memphis. The one-way fee is $125, and the carrier must fit under the seat. Soft-sided carriers are recommended, with a maximum footprint of 18" x 11" x 11". For pets too large for the cabin, Delta Cargo provides a separate, climate-controlled service—Delta does not accept pets as checked baggage on domestic flights, only through its cargo division.

Delta has invested in pet-friendly airport features, including pet relief areas at several hubs, though Memphis’s own terminal facilities serve all carriers equally. The airline’s official pet travel guidelines provide real-time updates on embargoes and health form requirements. Note that Delta requires a health certificate issued within 10 days of travel for cargo pets, and they may deny boarding if the pet shows signs of distress or aggression.

American Airlines: A Broad Range of Animals Accepted

American Airlines permits small dogs, cats, rabbits, and household birds in the cabin from Memphis. The fee is $125 per kennel, each way. Hard-sided kennels cannot exceed 19" x 13" x 9", while soft-sided ones should be no larger than 18" x 11" x 11". The combined weight of pet and carrier must stay under 20 pounds. Larger animals can travel as checked baggage or through American Airlines Cargo, though cargo options are limited on certain aircraft types.

American requires a health certificate for all checked and cargo pets, issued within 10 days of travel. The airline also enforces age minimums: puppies and kittens must be at least 8 weeks old for domestic flights, and 6 months old for international trips. Check the American Airlines pet travel page for a detailed fare table and aircraft-specific kennel size limits, as some smaller regional jets have tighter under-seat dimensions.

United Airlines: PetSafe Cargo for Larger Breeds

United welcomes small dogs and cats in the cabin for $125 each way, using a carrier that fits under the seat with a maximum size of 17.5" x 12" x 7.5". For larger pets, United’s PetSafe program offers a dedicated cargo service with temperature-controlled vans and pressurized holds. Memphis does not have an on-site PetSafe facility, but connections through hubs like Denver or Houston make it accessible. United’s cargo handling includes real-time tracking and trained animal care specialists.

United can be stricter with breed restrictions and seasonal embargoes. Snub-nosed dogs and cats may be prohibited from cargo travel during warmer months. Always verify your pet’s eligibility on the United pet policy page before you book. In-cabin pets are generally accepted year-round, subject to space availability.

Carrier Requirements and Airline-Specific Rules

Every airline publishes detailed guidelines for pet carriers, and failure to comply can result in denied boarding. Here is what you need to know.

Size and Weight Limits

In-cabin carriers must slide under the seat in front of you. While dimensions vary slightly, typical maximums range from 17–18 inches long, 11–12 inches wide, and 7.5–11 inches tall for soft-sided options. Soft-sided carriers often offer a bit more flexibility because they can compress to fit the space. Hard-sided kennels cannot exceed the airline’s stated maximums. The total weight of pet plus carrier seldom surpasses 20 pounds for in-cabin travel, so a small dog or cat breed is necessary.

For cargo or checked baggage, kennels must be IATA-compliant with secure metal hardware, ventilation on all sides, and enough interior space for the pet to stand, turn around, and lie down naturally. Airlines provide specific kennel size charts linked from their pet policy pages.

Material and Ventilation

All carriers must be leak-proof with absorbent bedding. The materials should be sturdy yet breathable. Soft-sided carriers with mesh panels are the most common choice for in-cabin travel. Hard-sided kennels for cargo need metal nuts and bolts, not plastic clips, to prevent escape. Never lock the kennel—airline staff must be able to open it if needed. Instead, use zip ties that can be cut.

Airline-Specific Nuances

Some airlines allow only one pet per carrier, while others permit two if they are the same species and size. Alaska Airlines allows two pets of similar size in one carrier for an extra $100 fee, as long as they fit comfortably. American Airlines allows one pet per carrier unless it's a mother with unweaned litter. Always double-check these subtle rules before purchasing a carrier.

Health and Documentation: What You Need Before You Fly

Proper paperwork is just as important as a well-ventilated kennel. Depending on your destination, you may need multiple health documents.

Health Certificate and Vaccinations

Most airlines require a health certificate issued by a USDA-accredited veterinarian within 10 days of travel for cargo pets, and sometimes for in-cabin pets as well. The certificate confirms your pet is free of infectious diseases and fit to fly. Rabies vaccination is mandatory for dogs and cats crossing state lines or international borders. Keep the original signed document with you, and bring a copy to attach to the kennel.

Age and Breed Restrictions

Puppies and kittens must be at least 8 weeks old and fully weaned to travel domestically. International travel often raises the minimum age to 6 months. Some breeds, particularly snub-nosed (brachycephalic) dogs like Bulldogs, Pugs, and Persian cats, may be restricted from cargo due to breathing difficulties at altitude. Check airline breed embargo lists carefully—restrictions apply even if the temperature is mild.

International Travel Considerations

Flying internationally with a pet from Memphis adds layers of complexity. Countries often require import permits, microchip identification, tapeworm treatment, or titer tests. The USDA APHIS pet travel website is the best starting point for researching destination requirements. Airline staff will verify these documents at check-in, and missing papers can result in a denied boarding.

Checking In with Your Pet at Memphis International Airport

The check-in process for pets at MEM is straightforward but demands extra time. Plan to arrive at least 90 minutes before departure for in-cabin pets, and 2–3 hours for cargo or checked baggage animals.

What to Expect at the Ticket Counter

For in-cabin pets, you will check in at the main ticket counter, pay the pet fee, and receive a cabin tag for the carrier. An agent may inspect the carrier to ensure it meets size and ventilation requirements. Then you proceed through security with your pet in the carrier—you will be asked to remove the pet from the carrier, send the carrier through the X-ray, and carry your pet through the metal detector.

For cargo or checked baggage pets, go to the designated cargo facility or the airline’s baggage drop, depending on the carrier. The pet will be taken by trained staff, and you must provide the health certificate and any other required forms. Confirm that the kennel is marked with “Live Animal” stickers and your contact information.

Pet Relief Areas at MEM

Memphis International Airport offers two post-security pet relief areas: one in Concourse A near gate A3 and another in Concourse C. Both are indoor rooms with artificial grass mats, waste bags, and sinks for cleanup. Pre-security, there are grassy areas outside the terminal entrances. These designated spots are the only places you can remove your pet from the carrier inside the terminal. Always allow time for a relief break before boarding—especially during delays or layovers.

Tips for a Stress-Free Flight with Your Pet

A little preparation can transform your pet’s flying experience from stressful to manageable. Implement these steps well ahead of your travel date.

Carrier Acclimation and Pre-Flight Routine

Start by leaving the carrier open at home with a favorite blanket or toy inside. Encourage short sessions of eating treats or playing near the carrier, gradually working up to closed-door time. A familiar scent reduces anxiety significantly. On flight day, feed a light meal 3–4 hours before departure and offer water until just before check-in. Avoid heavy meals that can cause an upset stomach. A brisk walk or play session before heading to the airport helps burn off nervous energy.

Choosing Between Cabin and Cargo

In-cabin travel is always preferable for small pets because it keeps them close and avoids the noise and temperature fluctuations of the cargo hold. However, some larger pets must travel in cargo. If your pet is a cargo candidate, choose a nonstop route whenever possible to minimize handling, and book early morning or late evening flights in summer to avoid extreme heat on the tarmac. Airlines will not accept cargo pets if ground temperatures exceed 85°F (or fall below 45°F) at any point along the route.

What to Pack for Your Pet

In your carry-on, pack a collapsible water bowl, a small bag of food, waste bags, and cleaning wipes. A spare collar with ID tags and a current photo of your pet can be a lifesaver if separation occurs. For cargo pets, freeze a small water dish attached to the kennel door so it thaws mid-flight, and tape a pouch of dry food to the outside of the kennel with feeding instructions.

Onboard Etiquette and Comfort

Once on the plane, place the carrier under the seat as directed. Do not open the carrier in the cabin. Speak softly to your pet, but avoid excessive attention that might raise excitement. A blanket draped over the carrier can create a dark, calming environment, provided it does not block ventilation. Most pets settle down once the engines start; the hum often soothes them.

Airport Amenities That Help Traveling Pet Owners

Memphis International Airport has invested in traveler-friendly features that make managing a pet easier. Free Wi-Fi throughout the terminal lets you pull up airline policy pages or check real-time weather if a connection goes awry. Family restrooms offer more space for a quick carrier check and clean-up. Quiet areas near the concourses provide a respite if your pet gets overstimulated by the crowds.

Outside the airport, pet-friendly attractions like Graceland’s outdoor walking areas can be a welcoming break if you are staying in Memphis before or after a flight. However, always confirm specific pet policies at any off-airport venue in advance.

Final Reminders Before You Book

Choosing the best airline for your pet from Memphis ultimately comes down to your animal’s size, temperament, and your destination. Alaska Airlines and Frontier remain top picks for consistently positive feedback, but Delta, American, and United all offer viable pathways with the right preparation. Review the airline’s current pet policy page a few days before travel—rules can change due to weather, aircraft swaps, or health advisories. Confirm your pet’s health documents are current, and arrive at the airport with plenty of time to spare. With the right groundwork, your pet’s journey from Memphis can be as calm and comfortable as possible.
