So, the cat is out of the bag—or hopefully, for the sake of the flight crew, very much in the bag. Flying with a four-legged companion isn't exactly a walk in the park, especially when navigating the specific maze of the Endeavor Air Pet Policy. Since Endeavor operates as Delta Connection, there’s this weird, double-layered reality where you’re following Delta’s overarching rules but squeezed into the much smaller physical footprint of a regional jet. It’s a lot. Between the carrier dimensions and the inevitable side-eye from the passenger in 4B, the prep work is basically a part-time job.

The Reality of Regional Jets: CRJs and Your Furry Cargo

Here is the thing about Endeavor Air—they fly Bombardier CRJ-700 and CRJ-900 aircraft. These aren't the massive wide-body planes where you can lose a small child in the overhead bins. These are snug. Actually, "snug" is a generous word. The space under the seat is the ultimate final boss of pet travel.

When looking at the Endeavor Air Pet Policy, the first hurdle is acknowledging that "one size fits all" is a lie. Because these planes have different configurations, that carrier you used on a cross-country Boeing 737 might not actually slide under the seat of a CRJ-900. It’s a game of millimeters. If the bag doesn’t fit, the pet doesn’t fly. Period. No amount of pleading with the gate agent changes the physical reality of a metal seat frame.

The Cost of Admission (The "Pet Fee" Tax)

Let’s talk money, because it always comes down to the wallet eventually. To bring a small dog or a cat into the cabin, there is a standard fee. Currently, for most domestic flights under the Delta/Endeavor umbrella, you’re looking at $95 each way.

• Domestic (US/Canada): $95 USD

• International: $200 USD (though Endeavor’s routes are primarily North American)

• Brazil: $75 USD

Is it pricey? For a creature that just sleeps under a seat and doesn't even get a Biscoff cookie? Absolutely. But that’s the toll for the Endeavor Air Pet Policy. You pay this at the check-in counter. Don’t try to use the self-service kiosk; it won't work for pet parents. You have to talk to a human, have them verify the paperwork (if applicable), and hand over the credit card.

What Animals Actually Make the Cut?

Not every pet is invited to the party. We’re talking cats and dogs, primarily. Small ones. If the dog is pushing 20 pounds, things start getting dicey. The Endeavor Air Pet Policy is pretty clear that the pet must be able to stand up and turn around inside the carrier. If the poor thing is hunched over like a gargoyle, the agent at the desk has every right to deny boarding.

Age Requirements

Puppies and kittens need to be at least 10 weeks old for domestic travel. If the flight is heading to the EU, they need to be 15 weeks. Why? Because tiny babies have tiny immune systems and flying is stressful. It’s for their own good, really, even if that "must-have" puppy from a breeder three states away is waiting.

The "One Pet Per Person" Rule (Mostly)

Usually, it’s one pet per carrier. However, the Endeavor Air Pet Policy allows for a few exceptions:

1. One female cat or dog can travel with her unweaned litter if they are between 10 weeks and 6 months old.

2. Two pets of the same breed and size (between 10 weeks and 6 months) can share a carrier if they are small enough to be comfortable. You still only pay one fee, which is a rare win in the airline industry.

The Carrier: Your Pet’s Tiny, Temporary Apartment

This is where most people mess up. The carrier is the most scrutinized piece of equipment you will own. It counts as your one carry-on bag. That means you get the pet carrier and one small personal item (like a purse or a laptop bag) that fits in the overhead. That’s it. If you’re a heavy packer, start looking into checked bag fees now.

Dimensions and Soft-Sided Secrets

The Endeavor Air Pet Policy doesn’t give one single, universal dimension because of those varying seat sizes we mentioned earlier. However, the gold standard is a soft-sided carrier. Why? Because they "squish."

If the under-seat height is 10 inches and your carrier is 11 inches, a hard-sided plastic kennel is a non-starter. A soft-sided bag, however, can be compressed that extra inch to clear the frame. Just make sure it has mesh on at least three sides for ventilation. Nobody wants a stifled cat.

Pro Tip: Check the specific "Delta Connection" aircraft for your flight number. If it says CRJ-700, the under-seat space is notoriously tight. Aim for a carrier that is no more than 11” x 11” x 17” if you want to breathe easy during boarding.

The Booking Process: Don't Leave it to Chance

You cannot just show up at the airport with a dog and hope for the best. Well, you can, but you’ll probably be driving home. Endeavor (via Delta) limits the number of pets allowed in the cabin per flight. It’s usually a first-come, first-served situation.

1. Book your flight.

2. Call Delta immediately. You have to manually add the pet to your reservation.

3. Confirm the spot. Sometimes the "pet quota" is already full—especially around holidays.

It’s a bit of a legacy system—having to actually call someone in 2026—but it’s the only way to guarantee that your dog isn't bumped because three other people got their Chihuahuas on the manifest first.

Navigating the Airport: From Security to the Gate

The Endeavor Air Pet Policy doesn't just stop at the airplane door; it starts the moment you hit the terminal.

The TSA Dance

TSA will make you take the pet out of the carrier. Read that again. Your cat, who is likely vibrating with terror, must be taken out of its safe space and carried through the metal detector while the empty carrier goes through the X-ray.

• Wear a harness. Even for cats.

• Keep the leash attached. * Do not let go. The last thing anyone needs is a feline sprint toward Gate C12.

The Lounge and the Gate

Once you’re through security, the pet stays in the carrier. Period. It doesn't matter how cute they are or how much they’re whining. It’s an FAA thing, and the agents are strict about it. Most airports have "Pet Relief Areas" now—usually a sad patch of fake grass in a room that smells like industrial bleach—but use them. It’s a long flight.

On the Flight: The "Under the Seat" Struggle

Once you board the Endeavor Air jet, the flight attendants are watching. The carrier must stay fully zipped and tucked under the seat in front of you for the entire duration—taxi, takeoff, and landing.

No Head-Popping

It’s tempting to unzip the top so your dog can get some head pats. Don't. If a flight attendant sees a head popping out, they have to give you "the talk." It’s about safety and allergies. Some people are deathly allergic to dander, and keeping the pet contained helps (slightly) to manage that.

Management of "Events"

If the pet decides to have a bathroom accident or a barking fit at 30,000 feet, keep your cool. Panicking makes the pet panic. Bring a few pee pads to line the carrier just in case, and maybe some travel wipes. The Endeavor Air Pet Policy is pretty unforgiving regarding "disruptive" animals. If a dog is barking incessantly, you might find yourself barred from future flights.

Health and Paperwork: The "Boring" Stuff

For domestic travel within the US, Endeavor/Delta generally doesn’t require a health certificate signed by a vet. However, individual states might. If you’re flying into Hawaii, for example, the rules are so intense they deserve their own novel.

Always carry a digital copy of your pet’s rabies vaccination records. It takes up zero space on your phone and saves a mountain of headache if an agent decides to be a stickler for the rules.

Summary Checklist for the Endeavor Air Pet Policy

To keep things simple (because this is a lot to digest), here is the "I’m at the airport and stressed" checklist:

• Carrier: Soft-sided, leak-proof, ventilated, and fits under a CRJ seat.

• Reservation: Called Delta and confirmed the "Pet in Cabin" (PETC) code is on the ticket.

• Fee: $95 ready to go.

• Identification: Collar, tags, and a sturdy leash.

• Age: Over 10 weeks old.

• Personal Item: One bag only, since the pet is your carry-on.

Final Thoughts (Without the "In Conclusion" Cliches)

Flying with a pet on a regional carrier like Endeavor is an exercise in logistics. It’s about measuring things three times and hoping the person in the seat next to you likes dogs. It’s about accepting that you’ll have no legroom for three hours because a carrier is occupying that space.

Is it stressful? Yeah, usually. But seeing your dog’s tail wag when you finally land in a new city makes the $95 and the cramped CRJ-900 legroom feel like a small price to pay. Just remember to breathe, keep the carrier zipped, and maybe pack an extra bag of treats—for both of you.
