Top Pet‑Friendly Airlines Flying from Detroit Metropolitan Airport

When you fly out of Warren, you are almost certainly departing from Detroit Metropolitan Airport. The following airlines all operate out of DTW and have clear, dependable policies for traveling with pets. Below you will find the details that matter most: which animals are allowed, what you will pay, how to prepare the carrier, and whether your pet can ride in the cabin or must go as cargo.

Delta Air Lines

Delta allows small dogs, cats, and household birds to travel in the cabin for a fee of $125 each way within the United States. Your pet must remain inside an approved carrier that fits completely under the seat in front of you—soft‑sided carriers with ventilation are recommended. Delta accepts one pet per passenger, and the carrier counts as your one carry‑on item. For larger animals or those that exceed the carry‑on size limit, Delta Cargo provides a separate climate‑controlled service with dedicated animal care staff. Cargo pets require a veterinary health certificate dated within 10 days of travel, and certain breeds (especially snub‑nosed dogs and cats) may be restricted during hot or cold months. Delta limits the total number of pets allowed in the cabin on each flight, so call Delta’s pet travel desk immediately after booking your ticket to secure a spot.

American Airlines

American Airlines accepts small cats and dogs in the cabin for a $125 one‑way fee. As with other carriers, the carrier must fit under the seat and meet American’s dimensions (soft‑sided carriers up to 18" x 11" x 11" are common). American also transports larger pets via its climate‑controlled cargo system, though you will need to book this option separately and arrive early to drop off your animal at the ticket counter. A health certificate issued within 10 days of departure is mandatory for cargo pets. American also restricts brachycephalic (flat‑faced) breeds in cargo due to respiratory concerns; if your pet falls into that category, cabin travel is the only option. For the most current size and breed restrictions, visit American’s pet policy page before finalizing your plans.

United Airlines

United’s cabin pet policy covers small dogs and cats for a $125 fee each way. The carrier must be leak‑proof, well ventilated, and able to slide under the seat. United’s PetSafe cargo program is one of the most comprehensive in the industry, featuring temperature‑controlled vans, pressurized holds, and 24/7 monitoring for animals traveling as checked baggage or cargo. Like other airlines, United requires a health certificate for cargo pets and advises against sedating your animal. They also impose seasonal embargoes—if temperatures are forecast to exceed 85°F or fall below 45°F at any point along the journey, your pet may not be accepted in cargo. Because cabin spots fill up quickly, it is wise to confirm your pet’s reservation through United’s customer service as soon as you book your flight.

Alaska Airlines

Often praised for its family‑friendly approach, Alaska Airlines allows small cats and dogs in the cabin for $100 each way. The maximum carrier dimensions (soft‑sided) are 17" x 11" x 9.5", so double‑check that your carrier fits before heading to DTW. Alaska also offers climate‑controlled cargo transport for larger pets, with similar health‑certificate requirements and seasonal restrictions. What sets Alaska apart is its flexibility: you can book a pet online while purchasing your ticket, and the airline allows two carriers in the first‑class cabin, provided both fit. From Detroit, Alaska’s nonstop routes to Seattle and other West Coast hubs make it a convenient choice for long‑distance moves with a furry companion. Check Alaska’s pet page for the latest fees and carrier rules.

Frontier Airlines

If you are looking for a budget‑friendly option, Frontier Airlines charges only $99 per pet for in‑cabin travel. Only small dogs and cats are permitted, and they must remain inside a soft‑sided carrier that fits under the seat. Frontier does not transport pets as checked baggage or cargo, so if your animal is too large for the cabin, you will need to choose another airline. The carrier size limit is 18" x 14" x 8", which is slightly wider than some competitors, but height is restricted. Frontier’s low base fare makes it appealing for short‑to‑medium trips, and several of its DTW routes connect to major destinations across the U.S. Always review Frontier’s pet travel guidelines before booking, as policies may change.

Southwest Airlines

Southwest permits small cats and dogs in the cabin for $95 each way, the lowest fee among major carriers. Pets must remain in a carrier (18.5" x 13.5" x 9.5") that stows under the seat in front of you. One pet per passenger is allowed, and Southwest does not accept animals in cargo. This makes it a solid choice if you are traveling with a small breed on routes that Southwest serves from Detroit (including many Midwestern and southern destinations). Southwest’s open seating policy can help you find a spot with a bit more floor space, but you will still need to follow the under‑seat rule. Reservations for your pet must be made over the phone after purchasing your ticket, so call early—each flight can only accommodate a handful of animals.

Essential Pet Travel Requirements You Should Know

No matter which airline you choose, all carriers enforce a core set of rules to ensure safety and compliance. Preparation is key. The following guidelines apply broadly, but specifics can vary by airline and destination, so always verify with the official policy.

Approved Carriers and Size Limits

For cabin travel, your carrier must be leak‑proof, well ventilated, and able to slide completely under the seat. Most airlines accept soft‑sided bags with mesh windows, which give your pet a bit more room while maintaining shape. Typical maximum dimensions are around 18" long x 11" wide x 11" tall, but some airlines shrink the height limit to 8" or 9" (Frontier and Alaska, for example). Hard‑sided kennels are accepted in cargo only; these must be sturdy, have secure metal doors, and include ventilation on at least three sides. The kennel should be large enough for your pet to stand, turn around, and lie down without touching the top. Always label the carrier with your name, phone number, and permanent address, and attach “Live Animal” stickers that the airline can provide.

Health Certificates and Vaccinations

A Certificate of Veterinary Inspection (CVI) is the standard document required for air travel. It must be issued by a licensed veterinarian within 10 days of your departure date—some airlines shorten this window to 5 days, so check ahead. The certificate confirms your pet is free of infectious diseases and appears fit to fly. Up‑to‑date rabies vaccination is mandatory for dogs, cats, and ferrets; additional vaccines (such as distemper or bordetella) may be required depending on the destination. If you are traveling internationally from Warren (with a connection abroad), you will also need an international health certificate endorsed by the USDA. The USDA APHIS pet travel website outlines entry requirements for different countries, including mandatory quarantine periods or microchip specifications.

Cabin vs. Cargo: Which Option Is Right for Your Pet?

In‑cabin travel is the least stressful option for most small pets because they stay close to you in a climate‑controlled cabin. The fee is usually $95–$125 each way, and the carrier counts as a carry‑on. If your pet is too large or your breed is not permitted in the cabin (for example, some airlines ban snub‑nosed breeds in cabin as well as cargo), you will need to use the airline’s cargo or checked‑baggage service. Cargo holds are pressurized and temperature‑controlled on commercial passenger flights, but your pet will be separated from you during the journey. Airlines such as United and Delta have dedicated animal‑handling programs. Note that extreme temperatures often trigger embargoes—if the forecast at any point along the route is above 85°F or below 45°F (the thresholds vary), your animal may not be accepted for cargo. Always have a backup plan during summer and winter trips.

Booking Early and Confirming Policies

Airlines cap the number of pets permitted on each flight, typically between four and seven cabin animals depending on aircraft size. The moment you finalize your own ticket, call the airline to add your pet to the reservation. Do not wait until check‑in at DTW—there is a good chance the pet spots will be sold out. Keep a copy of the airline’s current pet policy handy and save their customer service number. If you are traveling with a service animal, rules differ; emotional support animals are no longer recognized as service animals on U.S. flights and are treated as pets, so expect to pay the standard fee and meet carrier requirements.

Detroit Metropolitan Wayne County Airport (DTW) is well‑equipped for travelers with pets, but you must still follow airport regulations. Pets must remain inside their carriers or on a secure leash at all times inside the terminals. Fortunately, DTW has made the experience as smooth as possible with clearly marked relief areas and welcoming waiting spaces.

Pet Relief Areas and Amenities

DTW offers outdoor pet relief areas located just outside both the McNamara and Evans terminals. Each area has a grassy patch, waste bag dispensers, and trash receptacles. Airport staff recommend using these spots right before heading through security, as there are no relief stations airside. Inside the terminals, you can take advantage of quiet seating areas where your pet can decompress before boarding. While actual pet‑friendly lounges are not available, the wide concourses and less crowded gates at certain times of day offer plenty of room to find a calm corner.

Tips for a Smooth Airport Experience

Plan to arrive at DTW at least two hours before a domestic flight when traveling with a pet—three hours for international. That extra time lets you walk your dog outside, handle any check‑in counter formalities (especially if your pet is traveling as cargo), and calmly go through security screening. When passing through security, you will need to remove your pet from the carrier and walk through the metal detector holding your animal, or have the carrier X‑rayed separately. Practice quick removal and re‑entry with your pet ahead of time to reduce stress. Keep a small bowl and a water bottle handy to offer water after security, but avoid large meals within two hours of takeoff to prevent motion sickness.

Smart Strategies for a Stress‑Free Flight with Your Pet

Beyond airline policies and airport logistics, a few thoughtful preparations can dramatically improve your pet’s comfort in the air.

Acclimate Your Pet to the Carrier

Start carrier training at home at least two weeks before your flight. Leave the carrier open in a familiar room with a soft bed, favorite toy, and occasional treats inside. Gradually increase the time your pet spends inside with the door closed. This helps your animal associate the confined space with positive experiences, reducing anxiety on travel day. Also, place an item of your clothing inside—a worn T‑shirt, for instance—to provide a comforting scent.

Feeding and Hydration Schedule

Feed your pet a light meal four hours before heading to the airport. Avoid overfeeding, as a full stomach can worsen motion sickness. Offer water up to two hours before the flight, and attach a frozen water bowl or bottle to the carrier door (for longer cargo trips) so it melts gradually. Inside the cabin, you can offer a few sips after takeoff if your pet seems relaxed.

On the Day of Travel

Exercise your pet thoroughly before leaving for DTW—a long walk will help burn off excess energy. Try to keep your own demeanor calm; pets read our emotions. At the airport, speak in a soothing tone and reward calm behavior with quiet praise. Never sedate your animal without explicit veterinary advice, as high altitudes can amplify the effects of sedatives and cause breathing problems. Most airlines discourage sedation and may refuse to transport a heavily sedated animal.

Frequently Asked Questions About Flying with Pets from Warren

What is the total cost of flying a small dog in the cabin from Detroit?

One‑way cabin fees range from $95 (Southwest) to $125 (Delta, American, United). You will also need to factor in the cost of a carrier (if you do not already own one) and a veterinary health certificate, which typically runs between $50 and $100 depending on your clinic. Some airlines allow you to bring a second pet by purchasing an extra seat and second carrier, doubling the fee.

Can I sedate my pet for air travel?

Most airlines strongly advise against sedation because the changes in cabin pressure can interact unpredictably with sedatives, increasing the risk of respiratory distress. If you think your pet might need medication for severe anxiety, consult your veterinarian well in advance. They may recommend a mild anti‑anxiety supplement or a test dose at home to see how your pet reacts, but a full sedative is rarely approved for flight.

Are there any airlines that allow large dogs in the cabin?

No U.S. airline permits large dogs in the cabin unless they are service animals. All large pets must travel in the cargo hold. If your dog is too big for a carrier that fits under the seat, you will need to book a cargo or checked‑baggage slot. Check breed restrictions and seasonal temperature limits before you commit, especially for snub‑nosed breeds like Bulldogs or Persian cats, which may be banned from cargo entirely.

What if my pet gets anxious during the flight?

In the cabin, you can gently talk to your pet, place your hand on the carrier, and offer a familiar toy. Avoid opening the carrier during the flight—it is against FAA regulations and could allow a frightened animal to escape. For air travel anxiety, some owners find success with calming pheromone sprays (applied to the bedding) or a snug wrap like a ThunderShirt. Practice sessions inside the carrier at home will go a long way toward building confidence long before you arrive at DTW.
