Top Airlines for Pet Travel from Boston

When you’re flying out of Boston with a pet, you want an airline that actually cares about animals and doesn’t make the process a nightmare. Each airline sets its own rules about where pets can fly and how much you’ll pay.
American Airlines
American Airlines lets you bring a pet as a carry-on or as checked cargo, depending on their size and breed. If your pet fits in a carrier under the seat, they can ride in the cabin.
Bigger pets usually have to go in the cargo hold, which is climate-controlled but not always as temperature-stable as you’d hope. Advance booking is a must, and you’ll pay a pet fee.
There are breed restrictions to keep animals safe, so double-check that before you commit. Make sure your carrier fits their size rules.
If your pet travels as cargo, American offers animal transport services and some pretty detailed guidelines to help you prep.
Delta Air Lines
Delta Air Lines has a reputation for being pet-friendly, and a lot of travelers swear by them. Small pets can ride in the cabin if they fit under the seat.
Delta’s pet fee is usually a bit lower than some others, which is a nice surprise. For larger pets, you’ll need to use the cargo option, and they try to handle live animals with care.
Policies are pretty clear about health, paperwork, and carrier size. It’s a good idea to check breed restrictions and make sure your pet’s documents are ready so you’re not scrambling at the airport.
JetBlue Airways
JetBlue allows pets in the cabin on most flights out of Boston, as long as they fit under the seat in a carrier. You’ll pay a per-trip pet fee, but JetBlue tries to keep it reasonable.
They don’t offer a cargo option for pets on most routes, so the cabin policy is what matters here. The experience is usually straightforward, and staff seem genuinely friendly toward pets.
Book your pet’s spot early and double-check the carrier size. JetBlue spells out their rules pretty clearly, so you’re less likely to hit a snag at the last minute.
Pet Policies and Fees by Airline
Flying with your pet from Boston means learning the fees, carry-on rules, and what to do if your pet’s too big for the cabin. Airlines have limits on size, number, and breed to keep things safe and comfortable.
Carry-On Pet Rules
Most airlines let you bring small cats and dogs in the cabin, as long as they fit in a carrier that goes under your seat. Expect to pay about $125 each way for this.
Usually, you can bring only one or two pets per traveler in the cabin. Each pet has to meet the airline’s size and weight limits.
Your pet should be able to stand up and turn around in the carrier, so don’t try to squeeze them in something too small. Only cats and dogs are allowed as carry-ons—other animals usually have to fly as checked baggage or cargo.
You’ll need to show proof of health and vaccines before your pet can board.
Checked Baggage and Cargo Options
If your pet’s too big for the cabin, some airlines let them fly as checked baggage or cargo. You’ll drop off your pet at the ticket counter before your flight.
Fees for checked or cargo pets are higher than carry-on, so be ready for that. Cargo pets need a sturdy, well-ventilated crate that’s big enough for them to stand and turn around.
Advance notice is required so the airline can prep for your pet. Animal welfare rules are strict here—staff need to handle your pet carefully at every step.
If the weather is too hot or cold, the airline might not let pets fly in cargo to protect their health.
Breed and Size Restrictions
Airlines set breed and size rules mainly for safety reasons. Some breeds, like bulldogs or pugs, aren’t allowed to fly because of breathing issues.
There’s usually a weight limit for in-cabin pets—pet plus carrier can’t weigh more than 20 pounds in most cases. If your pet is bigger or can’t fit in the carrier, cargo is the only real option.
Breed restrictions can vary a lot, so always check with the airline before booking. It’s all about keeping pets safe and reducing their stress during travel.
Traveling with Service Animals and Emotional Support Animals
If you’re flying with a service or emotional support animal, there are extra rules you have to follow. Knowing what documents you need and what kind of carrier is allowed can save you a lot of hassle.
service animals
Service animals help people with disabilities, and airlines like United let you bring up to two service dogs for free if you meet the requirements. You’ll need to show paperwork confirming the animal’s role.
Federal rules say airlines have to accept legitimate service animals in the cabin, and they don’t need to stay in a carrier. Be ready to show forms or certificates if the airline asks.
Policies can differ a bit, so it’s always smart to check with your airline before you fly.
service dogs
Service dogs do specific jobs like guiding, alerting, or protecting. Alaska Airlines allows psychiatric service dogs, treating them like other service animals under the law.
You usually don’t have to put your service dog in a carrier. Emotional support animals are a different story, though—most airlines don’t treat them as service animals anymore.
Let the airline know about your service dog when you book. You might have to fill out forms about training and behavior.
| Key Points | Details |
|---|---|
| Number of animals | Up to two service dogs on United free |
| Proof required | Documentation verifying service status |
| Carrier requirements | Usually no carrier needed for service dogs |
| Airline policies vary | Check airline rules before travel |
Logistics, Safety, and Arrival Considerations
Traveling with your pet from Boston means planning ahead. You’ll need to get your pet ready, show up at the airport early, and take care of any paperwork or customs stuff.
Preparing Your Pet for the Flight
Get your pet used to its carrier before the flight. If they’re flying in the cabin, use an airline-approved carrier that fits under the seat.
For cargo, the carrier needs to be extra sturdy and ventilated. Visit the vet for updated vaccinations and a health certificate close to your travel date.
Don’t feed your pet right before flying—nobody wants a nauseous animal—but make sure they have water. Label the carrier with your contact info and your pet’s name.
A familiar blanket or toy can help them feel less anxious. Try a few short trips in the carrier before the big day to make it less scary.
Arriving at Boston Logan International Airport
Get to the airport early, especially if your pet is flying cargo. Airlines like Delta want pets at the cargo facility 4 to 6 hours before takeoff.
Follow the airline’s instructions for pet drop-off at Logan. Staff will check the carrier and your pet to make sure everything’s good.
Keep your pet calm and hydrated while you wait. Some airlines have weather rules, so check the forecast before you go.
Double-check any extra fees so you’re not surprised at the counter.
Customs Clearance
If your pet’s headed overseas, customs clearance is a must. You’ll need vaccination records, health certificates, and any import permits.
Every country seems to have its own set of rules—best to double-check those before you go. At customs, inspectors might look over your pet and all those documents.
There could be a quarantine, depending on where you’re landing and what kind of animal you’ve got. Animal welfare matters, so officials do take safety checks seriously.
Getting the paperwork right can really save you headaches at the border. It’s smart to keep in touch with your airline and customs folks so you know exactly what’s needed for your pet to get in.
