Best Airlines for Pets from Orlando – A Comprehensive Overview

Flying with a pet out of Orlando International Airport (MCO) doesn’t have to be a logistical nightmare. The right airline can turn a potentially stressful experience into a manageable journey for both you and your animal. While nearly every major U.S. carrier has a pet policy, not all of them enforce it with the same clarity or offer the same level of comfort. From cabin allowances to cargo hold conditions, the differences matter.

Alaska Airlines and Frontier Airlines consistently earn high marks among travelers departing Orlando with dogs, cats, and even small household birds. They stand out for straightforward fee structures, fewer breed restrictions for in-cabin travel, and a reputation for handling animals with care. But they aren't the only options. Airlines like Delta, American, United, and JetBlue also serve MCO and provide pet travel services, each with its own set of rules, fees, and seasonal embargoes you need to untangle before booking.

This guide breaks down the top carriers for pet travel from Orlando, compares in-cabin and cargo options, and walks you through the preparation and airport procedures that keep your pet safe and comfortable.

Alaska Airlines: A Consistent Favorite for In-Cabin Pets

Alaska Airlines operates multiple daily departures from Orlando, and its pet travel policy is among the most accommodating in the industry. For a fee of $100 each way, you can bring a small dog, cat, rabbit, or household bird into the cabin, provided the animal stays inside an approved carrier under the seat for the entire flight. The carrier must have ventilation on at least two sides and be leak-proof, but Alaska does not mandate hard-sided kennels for in-cabin travel—soft-sided carriers are welcome as long as they fit within the underseat dimensions (17″ x 11″ x 9.5″ on most aircraft).

Alaska also accepts pets as checked baggage or cargo on many routes, with larger dogs and cats traveling in temperature-controlled holds. The airline’s communication about hot-weather embargoes is unusually transparent, a critical advantage when flying from Orlando during the summer. If the forecast calls for ground temperatures above 85°F at any point along the journey, Alaska will not accept brachycephalic (snub-nosed) breeds like pugs, bulldogs, and Persian cats for travel in the cargo hold—a restriction grounded in animal welfare research.

Booking a pet spot on Alaska is straightforward but competitive. Only a limited number of animals are allowed per flight, and reservations are first-come, first-served. Call the airline the moment your itinerary is firm to lock in the in-cabin fee and avoid disappointment.

Frontier Airlines: Low-Cost Pet Travel Without Complicated Rules

Frontier has grown its presence at Orlando, and its no-frills model extends to pet travel in a refreshing way. The Frontier pet policy allows dogs, cats, rabbits, guinea pigs, hamsters, and small household birds to fly in the cabin for a flat $99 fee per direction. Unlike some carriers that treat pets as carry-on baggage and levy additional fees, the pet charge includes the animal’s space under your seat. The carrier maximum dimensions are 18″ long x 14″ wide x 8″ high, meaning many soft-sided carriers that fit Alaska will also work for Frontier.

Frontier does not transport pets as checked baggage or cargo at all—only in the cabin. That simplifies decision-making if your pet is too large to ride under the seat. For many small animals, however, the straightforward policy and low price make Frontier a top pick from Orlando, especially for budget-conscious travelers. The airline limits the total number of pets per flight, so booking early is still essential. One quirk: Frontier requires that your pet remains inside the carrier at all times, even during boarding and deplaning, and the carrier counts as your personal item unless you pay for a carry-on bag.

Other Major Airlines Flying Pets from MCO

Beyond Alaska and Frontier, several other carriers offer viable pet travel options from Orlando, though policies can be more complex.

Delta Air Lines: Delta accepts small dogs, cats, and household birds in the cabin on most domestic flights for a $95 fee each way when paid in advance (higher at the airport). The Delta pet travel page spells out strict carrier size rules that vary by aircraft type, so you must check the exact plane operating your route. Delta also ships pets as cargo through Delta Cargo if they don’t fit under the seat. The airline imposed a ban on emotional support animals in 2021, so only trained service dogs receive free cabin access, tightening the definitions you need to understand if your pet provides assistance.

American Airlines: American services Orlando heavily, and its pet policy covers both cabin and cargo options. In-cabin pets cost $125 each way, with carriers limited to 19″ x 13″ x 9″ for soft-sided models. Checked pets and cargo shipments require hard-sided kennels and come with higher fees and earlier drop-off times. American restricts cabin pets to cats and dogs only, and pit bull-type breeds, among others, are prohibited from cargo travel. The airline’s embargo on checked pets during extreme summer temperatures closely matches Alaska’s, but enforcement can vary by airport, so checking in advance at MCO is wise.

United Airlines: United charges $125 for in-cabin pets, accepting only cats and dogs. Hard-sided and soft-sided carriers are permitted, with dimensions capped at 18″ long x 11″ wide x 11″ high for hard kennels and slightly larger for soft carriers on some aircraft. United’s PetSafe cargo program is the only option for larger animals, and breed restrictions apply heavily—over 20 breeds are banned from cargo due to respiratory risks. From Orlando’s humid climate, these embargoes kick in during summer, so plan flights outside the hottest hours.

JetBlue: Through its JetPaws program, JetBlue permits small cats and dogs on Orlando flights. The fee is $125 each way, and only four pets total are allowed per flight—making advance booking mandatory. JetBlue provides a travel checklist and a carrier tag at check-in, a small but helpful touch. Carrier dimensions must not exceed 17″ L x 12.5″ W x 8.5″ H. The airline does not accept pets as checked baggage or cargo, so in-cabin is the sole pathway.

Southwest Airlines: Southwest does not fly pets out of Orlando as it only allows fully-trained service dogs on board, with emotional support animals excluded. Pet owners looking for low-cost base fares will need to look to Frontier or other carriers instead.

Understanding Pet Travel Options: In-Cabin, Checked Baggage, and Cargo

Airlines typically partition pet travel into three categories, and your choice depends on your pet’s size, breed, and your comfort with separation. Knowing the difference helps you select the safest and most practical method.

In-Cabin Pet Travel: What to Expect

In-cabin travel is the only choice for small pets, and it’s the least stressful because your animal stays close to you. Carriers must slide under the seat in front of you, meaning your pet remains in a climate-controlled cabin the entire time. Airlines enforce a strict “no carrier out of the bag” rule, so your dog or cat must be able to stand up, turn around, and lie down comfortably inside the carrier without protruding.

Fees for in-cabin pets range from about $95 to $150 each way. Most carriers limit this option to cats, dogs, and occasionally rabbits or birds. There’s also a limit of one pet per passenger, and no more than a handful of pets across the entire plane. Booking the pet spot usually requires a direct call to the airline after purchasing your ticket. Because these spots are few, flexibility on travel dates can make or break your plans.

Checked Pets and Cargo Options: When They Are Necessary

If your pet exceeds the weight or size limit for the cabin, checked baggage as a pet or full cargo shipping becomes the default. Checked pets travel in the aircraft’s forward or aft cargo hold, a pressurized and temperature-controlled compartment separated from luggage. You drop the animal at the ticket counter and pick it up at baggage claim. Airlines like American, Delta, Alaska, and United offer this service, with fees starting around $150 to $250 each way, depending on weight and destination.

Pure cargo shipping, offered through programs such as United PetSafe or Delta Cargo, is used for very large dogs, international relocations, or when a flight has reached its checked pet capacity. Cargo holds are maintained at safe temperatures, but the experience is more detached—you deliver the animal at a separate cargo facility hours before departure. Because Orlando’s summer heat can trigger ground temperature embargoes, early morning or evening flights are strongly recommended to avoid having your pet refused.

Breed restrictions are the catch. Snub-nosed dogs and cats (Bulldogs, Pugs, Boxers, Persian cats, etc.) are frequently barred from cargo travel year-round due to breathing difficulties that worsen with stress and temperature fluctuations. If your pet belongs to one of these breeds, in-cabin travel is the only reliable method from Orlando.

Essential Preparation for Flying with a Pet from Orlando

Pulling together the right paperwork, gear, and health clearances well ahead of your departure date turns a chaotic airport scramble into a smooth procedure. The Orlando International Airport pet travel experience depends on this groundwork.

Carrier Requirements and Getting Your Pet Ready

Start with an airline-approved carrier that fits your pet correctly. Measure from the tip of the nose to the base of the tail for length, and from the floor to the top of the shoulders for height. Add two to three inches to each dimension to ensure enough room. Soft-sided carriers are generally preferred for in-cabin travel because they compress slightly to fit under seats with varying contours. For checked or cargo travel, a hard-sided kennel with ventilation on all four sides, a spring-lock door, and metal nuts and bolts (not plastic clips) is mandatory. Many airlines require a sturdy handle and a water bowl attached to the door.

Introduce the carrier weeks before your trip. Leave it open in your living area with treats inside so your pet associates it with positive experiences. Take short car rides with the animal inside to simulate the motion and confinement of a flight.

Health Documents and Vaccination Proofs

A health certificate issued by a licensed veterinarian within 10 days of travel is the standard domestic requirement. The certificate confirms your pet is free from infectious diseases and fit to fly. Some states require a Certificate of Veterinary Inspection (CVI) that extends beyond a generic health check. If you’re flying internationally from Orlando, the destination country may demand an international health certificate, proof of a microchip, rabies titer test results, and even an import permit. The USDA APHIS Pet Travel website is the authoritative resource for these layered requirements.

Most airlines also require a current rabies vaccination certificate for dogs and cats, regardless of destination. JetBlue and others may ask for additional vaccinations depending on your itinerary. Have your vet print multiple copies and keep a digital set on your phone.

Special Considerations for Orlando’s Climate

Orlando’s subtropical weather directly impacts when and how your pet can fly. Summer heat often activates airline embargoes on live animal travel in cargo holds between roughly May and September. If your trip falls in that window, book an early morning flight (before 10 a.m.) or an evening departure to avoid peak ground temperatures. Even for in-cabin pets, arriving at the airport during cooler hours means less time exposed to hot tarmac air during boarding and deplaning.

Hydration is another Florida-specific factor. While you can’t put water bowls inside carriers that might spill, offer your pet water right before leaving for the airport and again just before heading through security. MCO has designated pet relief areas before and after security where you can give your animal a final bathroom break.

Pro Tips for a Smooth Pet Travel Experience from Orlando International Airport (MCO)

Navigating the airport with an animal adds a layer of logistics, but seasoned pet travelers develop a rhythm that minimizes stress.

Arrive at least two and a half hours before a domestic flight if traveling with a pet, especially if you need to check the animal as baggage at the ticket counter. The Main Terminal at MCO has multiple airline counters spread across A and B sides, so verify your airline’s exact location ahead of time to avoid crisscrossing the terminal with a carrier.

At TSA screening, you’ll remove your pet from the carrier while the empty bag goes through the X-ray machine. A calm, leashed walk through the metal detector or a hand-carry of your pet (if small enough) is required. Practice this with your animal beforehand, and use a properly fitted harness or collar to prevent escape in the noisy security area. The airport’s pet relief stations, located near gates in Terminals A and B, offer turf-like surfaces and waste disposal bags—plan a final visit just before boarding begins.

Keeping Your Pet Calm During the Journey

Reduce anxiety with familiar scents and a predictable routine. Place a shirt you’ve worn inside the carrier to give your pet a comforting smell. Avoid feeding a full meal within four hours of departure to prevent nausea, though a few small treats are fine. A light cover thrown over the carrier can muffle visual stimuli without blocking ventilation.

During the flight, never open the carrier, and don’t give tranquilizers unless prescribed by your veterinarian for the specific purpose of air travel—many sedatives affect breathing and balance at altitude. Instead, a calming pheromone spray (like Adaptil for dogs or Feliway for cats) applied 30 minutes before boarding can help without medical risk.

By choosing an airline that prioritizes pet welfare and sticking to a thorough preparation checklist, your trip from Orlando can be just another adventure for your animal. A little effort upfront pays off in a tail wag or a content purr at the destination.
