Traveling with your pet from Ann Arbor, Michigan, requires more than just a reservation—it demands an airline with transparent animal handling policies, thoughtful in-cabin options, and a track record of pet safety. Alaska Airlines and Frontier Airlines consistently rank among the best airlines for pets from Ann Arbor because of their clear pet travel programs and a focus on reducing stress for both animals and owners. However, several other carriers operating out of Detroit Metropolitan Wayne County Airport (DTW) and nearby regional airports offer reliable service tailored to different needs, budgets, and pet sizes.

Ann Arbor’s proximity to DTW gives you access to a broad network of major airlines that understand the practical side of pet travel. Whether you’re bringing a small dog in the cabin, checking a larger animal as baggage, or arranging cargo transport, picking the right carrier shapes the entire experience. This guide breaks down top airlines, essential policies, ground transportation to the airport, popular destinations, and how to prepare your pet for a safe, comfortable flight.

Top Airlines for Traveling with Pets from Ann Arbor

The best airlines for pet owners combine in-cabin pet allowances, reasonable fees, straightforward booking processes, and a genuine commitment to animal welfare. Here’s a closer look at the carriers that stand out for travelers departing from Ann Arbor area airports.

Alaska Airlines: A Leader in Pet-Friendly Travel

Alaska Airlines has built a strong reputation for pet travel, and it remains one of the most recommended options for Ann Arbor residents flying with animals. The carrier allows small cats, dogs, rabbits, and household birds to travel in the cabin for a fee, provided the pet remains in an approved carrier that fits under the seat in front of you. Alaska’s in-cabin pet fee is $100 each way, and the airline caps the total number of pets per flight, so you’ll want to book early.

For larger dogs, Alaska offers a checked baggage pet option on many flights, though this service has size and breed restrictions, and is not available during extreme temperature conditions. Alaska also operates a separate cargo program called Alaska Pet Connect for animals traveling without their owners or for those exceeding checked baggage limits. The airline’s partnership with Detroit Metro means you can access multiple daily nonstop routes to the West Coast and beyond without changing carriers—an advantage that helps minimize transit stress for your pet.

What makes Alaska especially attractive is its customer-first approach: flight attendants are trained to assist with pet-related questions, and the airline provides clear, updated guidance on pet travel online. You’ll want to review the aircraft-specific cargo hold requirements if your pet is traveling as checked baggage, as not all planes have climate-controlled compartments suitable for animals.

Frontier Airlines: Affordable and Pet-Inclusive

Frontier Airlines offers a straightforward in-cabin pet program that appeals to budget-conscious travelers from Ann Arbor. Unlike many carriers, Frontier focuses exclusively on in-cabin pet transport—it does not accept pets as checked baggage or cargo. This simplifies the decision for owners of small cats, dogs, rabbits, guinea pigs, hamsters, or household birds. The pet travel fee on Frontier is typically $99 per flight segment, and like Alaska, the carrier limits the number of pets on each flight, so advance reservations are essential.

Frontier’s operational model at DTW provides a range of direct and connecting options. The airline’s no-frills approach keeps base fares low, and you pay only for the extras you need—including your pet’s spot. Be aware that the under-seat space on Frontier’s A320-family aircraft can vary slightly, so measuring your carrier carefully against Frontier’s pet carrier dimensions (usually about 18" x 14" x 8") is a must. Also, because Frontier does not offer pet options for checked baggage, the maximum weight for a pet and carrier combined should stay under 30 pounds to fit comfortably.

Frontier’s tight connection windows on some itineraries can be a challenge if you’re traveling with a pet, so opt for nonstop flights or longer layovers whenever possible. Still, for short-haul trips to destinations like Orlando, Denver, or Las Vegas, Frontier ranks among the best choices for keeping your pet close throughout the journey.

Southwest Airlines: In-Cabin Pets with No Cargo Fees

Southwest Airlines operates a pet-friendly in-cabin program that many Ann Arbor travelers appreciate for its simplicity and consistency. Small cats and dogs can ride in an approved carrier under the seat for a pet fare of $95 each way. Southwest does not transport pets as checked baggage or air cargo, so if your animal is too large for the cabin, you’ll need to look at other carriers.

One advantage of flying Southwest out of DTW is the airline’s open seating policy. While this means you cannot reserve a specific seat in advance, families traveling with pets can board early with a checked-in pet to secure a spot that accommodates the carrier easily. Southwest’s high frequency of flights to destinations across the U.S. gives you flexibility, and its customer service is generally responsive to pet travel inquiries. Keep in mind that the airline requires pets to remain in their carriers for the entire flight, with the carrier door closed and latched.

Also worth noting: Southwest’s pet policy does not cover rabbits, birds, or other non-canine/feline animals, so if you have a less common pet, Alaska or Frontier might be a better fit.

Avelo Airlines: Low-Cost and Pet-Friendly From Smaller Airports

Avelo Airlines has carved out a niche for low-cost, unbundled travel and welcomes pets in the cabin for a fee comparable to other budget carriers. While Avelo does not serve DTW, its presence at airports like Tweed New Haven (HVN) opens up a different route strategy for Ann Arbor pet owners willing to start their trip from a smaller, less congested hub. If you’re visiting family in southern Connecticut or planning a New England escape, flying into HVN with a pet can dramatically reduce airport chaos compared to major metros.

Avelo’s in-cabin pet policy allows small dogs and cats in soft-sided carriers, and the pet fee ranges from $95 to $125 depending on route and booking timing. Because Avelo emphasizes point-to-point nonstop flights, the risk of a missed connection or long layover that could stress your animal is minimized. However, you’ll need to arrange ground transport from Ann Arbor to the chosen departure airport, which could mean a road trip to connect via Flint or even driving to HVN directly if the overall itinerary makes sense. The trade-off can be worth it for a peaceful, direct flight with your pet tucked securely under the seat.

Delta Air Lines: The Hometown Carrier at DTW

As the dominant carrier at Detroit Metropolitan Airport, Delta Air Lines naturally comes up for Ann Arbor pet owners. Delta allows small cats, dogs, and household birds to travel in the cabin for a fee (typically $95 each way within the U.S.), with strict carrier dimensions and advance booking requirements. For larger pets, Delta Cargo offers a separate shipping service, but it is important to note that Delta does not accept pets as checked baggage on most domestic flights. Instead, pets traveling without their owners or those too large for the cabin must go through Delta Cargo, which operates under different booking, drop-off, and pick-up procedures.

Delta’s temperature-restriction policies also apply to both in-cabin and cargo travel, and the airline may refuse pets during extreme heat or cold. This is a critical factor for Ann Arbor travelers during Michigan’s harsh winters or hot summers. If you’re considering Delta, check the weather forecast at departure, arrival, and any connection points. Despite these constraints, Delta’s extensive network from DTW to domestic and international destinations means you can often find a workable itinerary if you plan ahead and understand the cargo logistics.

Other Carriers: American, United, and What to Watch For

American Airlines and United Airlines both operate out of DTW and offer in-cabin pet travel for small dogs and cats, with fees generally between $125 and $150 each way. United’s PetSafe program also accepts larger animals as cargo, but policies around checked baggage pets have tightened in recent years. American’s carry-on pet program is widespread, but breed restrictions apply, particularly for snub-nosed dogs and cats. If you’re flying one of these carriers, review the latest pet embargo list before booking, as some cities and times of year automatically block pet travel.

Regardless of the airline, always confirm that your pet’s carrier meets the exact under-seat dimensions of the aircraft type operating your flight, because regional jets often have less space than mainline planes. Calling the airline to add your pet to the reservation immediately after booking is a best practice that secures your spot and gives you a chance to ask route-specific questions.

Key Pet Travel Policies You Need to Know

Before you book, understand the three ways pets typically fly: in the cabin with you, as checked baggage (traveling in a pressurized, temperature-controlled cargo hold), or via standalone cargo services. Each method carries different fees, restrictions, and booking windows.

  • In-Cabin: Small pets that fit in a carrier under the seat; most common and recommended. Fees range from $95 to $150 each way. Must remain in carrier for full flight.
  • Checked Baggage: Larger pets in a crate placed in the cargo hold. Fees often higher ($200–$400). Not available on all airlines or during temperature extremes. Requires an airline-approved hard-sided crate.
  • Cargo: Standalone shipping for pets traveling alone or as freight. Booked separately from your ticket. Requires IATA-compliant crates, health certificates, and drop-off/pick-up at cargo facilities.

Almost all airlines mandate that you book your pet’s travel in advance—often by phone, because online systems cannot always handle pet additions. Also, most carriers cap the total number of pets on a given flight, so early booking is critical. Be aware of breed-specific restrictions, particularly for brachycephalic (flat-faced) animals like pugs, bulldogs, and Persian cats, which are often barred from cargo travel due to respiratory risks.

Detroit Metro Airport: Navigating DTW with Your Pet

DTW is the primary airport for Ann Arbor pet owners, and it has invested in facilities that make animal travel more manageable. Both the McNamara Terminal (used by Delta and its partners) and the Evans Terminal (used by Frontier, Southwest, American, and others) feature designated pet relief areas. These are located post-security as well as outside the terminals, so you can walk your dog before checking in and again during a layover.

When moving through security, you will need to remove your pet from the carrier and carry or leash them through the metal detector while the carrier goes through the X-ray machine. TSA officers are generally accustomed to this process, but it helps to have a well-fitted harness or leash handy. DTW’s pet relief stations are cleaned regularly, but bringing your own waste bags and a small bowl for water is a good idea. If you’re traveling with a cat or a small animal that does not walk on a leash, request a private screening room to safely transfer the pet from carrier to your arms without risking escape.

Alternative Airports and Ground Transportation from Ann Arbor

While DTW is the most convenient major airport, you might also consider smaller options for specific routes or lower crowds. Getting to any of these airports with your pet requires reliable ground transportation.

Michigan Flyer and Deluxe Motorcoach: Stress-Free Rides to DTW

The Michigan Flyer runs direct motorcoach service between Ann Arbor, East Lansing, Brighton, and DTW multiple times a day. This service allows pets if they are secured in a carrier that fits on your lap or under the seat. The buses are clean, equipped with Wi-Fi, and eliminate the need to navigate airport parking or coordinate rideshare. Deluxe Motorcoach offers a similar route with reserved seating and additional legroom, which can be helpful if you’re traveling with a larger pet carrier that needs space.

Using a motorcoach also lets you avoid the stress of driving and parking at DTW, which can be especially valuable when you’re managing luggage and a pet. Both operators recommend calling ahead to confirm pet-acceptance policies on the day of travel, as space constraints can apply.

Other Nearby Airports: Flint Bishop and Capital Region International

If you’re open to a slightly longer drive, Flint Bishop Airport (FNT) and Capital Region International Airport (LAN) in Lansing can serve as alternatives. These smaller airports have fewer crowds, shorter security lines, and sometimes lower pet fees with certain carriers. While flight options are more limited, you might find that the calmer environment reduces your pet’s anxiety. Check which airlines operate from these airports—Southwest and Allegiant serve Flint, for example—and verify their pet policies before committing.

Certain destinations stand out for their pet-friendly infrastructure, outdoor spaces, and ease of travel with animals. Pairing the right airline with the right city makes all the difference.

New Haven and Southern Connecticut via Avelo at HVN

Tweed New Haven Airport offers a less stressful arrival for pets compared to congested Northeast hubs. With park-lined streets, pet-friendly cafés near Yale’s campus, and plenty of walking trails, New Haven is a welcoming destination for you and your dog. Southern Connecticut’s shoreline also features several dog-friendly beaches in the warmer months. Traveling from Ann Arbor to HVN usually means connecting through a smaller airport first, but the laid-back vibe is worth the extra logistical step.

New York and New England: Big Cities, Pet-Friendly Stops

Flying into New York’s major airports—JFK, LaGuardia, or Newark—from DTW takes just over an hour, making it a manageable trip for pets. Each airport has pet relief areas beyond security, and the city’s network of parks, including Central Park’s designated off-leash hours, means your dog doesn’t have to stay cooped up. Beyond New York, Boston and Portland, Maine, offer pet-welcoming cobblestone walks, brewery patios, and coastal trails. A nonstop DTW-to-Logan flight on Delta or JetBlue with an in-cabin pet keeps the journey short and simple.

North Carolina: Charlotte and Wilmington’s Coastal Charm

Charlotte Douglas International Airport (CLT) is a major hub with several pet relief areas, making it a convenient connection point or final stop. Once you arrive, Charlotte’s many greenways and dog-friendly restaurants create a relaxed atmosphere. Wilmington’s historic riverwalk and nearby Carolina Beach (which allows dogs on leash year-round) are especially appealing for a coastal getaway. Both cities are accessible via direct flights from DTW on American Airlines, which supports in-cabin pets under its standard policy.

International Travel: Crossing Borders with Your Pet

Flying internationally with a pet from Ann Arbor typically involves connecting through larger hubs like DTW before heading abroad. Most countries require a valid health certificate, proof of rabies vaccination, and sometimes a microchip or specific import permit. The USDA APHIS Pet Travel website provides country-specific requirements and can help you prepare paperwork weeks ahead of departure.

When choosing an international carrier from DTW, look at Delta, United, or Lufthansa (via connecting partner flights), all of which have established pet cargo or in-cabin programs for certain routes. Keep in mind that some nations restrict pet entry by season or require quarantine, so your planning should start three to six months before travel. An airline that clearly communicates international pet policies—and assigns a live animal coordinator when needed—will dramatically reduce your anxiety at customs.

Preparing Your Pet for Air Travel

A well-prepared pet is a calmer pet. Focus on health documentation, carrier training, and understanding airline temperature embargoes to avoid last-minute surprises.

Health Certificates and Vaccination Requirements

Most airlines require a health certificate issued by a licensed veterinarian within 10 days of travel (or 30 days for some cargo programs). This certificate confirms your pet is fit to fly, free of contagious diseases, and current on core vaccinations. For international travel, an accredited veterinarian may need to endorse the certificate, and you may require an additional USDA endorsement. Schedule your vet visit well in advance, and keep physical and digital copies of all documents with you at check-in.

Choosing the Right Carrier

Your pet’s carrier must be airline-approved, well-ventilated, leak-proof, and large enough for the animal to stand, turn around, and lie down naturally. Soft-sided carriers are popular for in-cabin travel because they can compress slightly to fit under seats, but they must have secure zippers and mesh panels. Hard-sided crates are mandatory for cargo, with metal nuts and bolts securing the halves—plastic snap closures alone are not accepted. Label the carrier with your contact information, your pet’s name, feeding instructions, and a “Live Animal” sticker for cargo crates.

Managing Your Pet’s Anxiety During Flight

Acclimate your pet to its carrier weeks before the trip by leaving it open at home with comfortable bedding and treats. Short car rides in the carrier help simulate the motion of travel. On the day of the flight, avoid sedation unless specifically prescribed by your vet, as high altitudes can affect breathing. Instead, use calming aids like a familiar blanket, a shirt with your scent, or vet-approved pheromone sprays. Provide water right up until you check through security, and opt for a leash and collar over a harness if you’ll need to quickly remove them for TSA screening.

Temperature and Embargo Restrictions

Nearly all airlines impose temperature embargoes—if forecast highs or lows at any point on your itinerary exceed certain limits (typically above 85°F or below 45°F for cargo, and extreme cold or heat for tarmac time), pets may be denied boarding. Summer and winter travel from Michigan are particularly susceptible. Book early-morning or late-evening flights to avoid the hottest part of the day, and consider direct flights to eliminate layovers where temperature regulations might strand your pet.

Final Tips for a Smooth Pet Flight from Ann Arbor

Start by narrowing down your airline choice based on whether your pet will fly in the cabin or needs cargo options. Verify the dimensions of the specific aircraft assigned to your route, not just the airline’s general maximum. Reserve your pet’s spot over the phone immediately after booking your ticket, and call back 24 hours before departure to confirm. At the airport, arrive at least an hour earlier than you normally would—check-in for pets often requires additional paperwork verification at the counter. Pack a small go-bag for your pet with a collapsible water bowl, treats, waste bags, and a clean absorbent pad for the carrier.

Traveling with your pet from Ann Arbor doesn’t have to be a nerve-wracking ordeal. By selecting an airline with a proven track record—Alaska, Frontier, Southwest, or Delta for most needs—and navigating DTW’s pet-friendly infrastructure wisely, you can transform the journey into a manageable, even enjoyable, part of your trip. The right preparation, combined with an airline that genuinely prioritizes animal comfort, ensures your furry companion arrives at your destination as ready for adventure as you are.
