Anyone who has spent too many hours sitting on cold airport floors—half-zipped duffel bags everywhere, that unmistakable smell of a nervous animal in the air—knows one thing fast: navigating the Korean Air Pet Policy requires patience, preparation, and a deep breath. This isn’t tossing a carry-on into the overhead bin and calling it a day. It’s a process. A real one.

Gate agents have turned travelers away over carriers that were “too tall” by barely half an inch. No exaggeration. It’s rough to watch. Korean Air, to be fair, is more reasonable than many budget nightmare airlines, but the rules are followed closely. Miss a detail, skip a measurement, assume flexibility—and the journey can end faster than a 6:00 a.m. security line shuts down small talk.

The "Must-Know" Basics (Before You Even Buy a Ticket)

First off—don't just book your flight and assume Fido is invited. You have to request approval. For international flights, they need 48 hours' notice. Domestic? You can squeeze by with 24 hours.

But honestly? Call them the second you think about booking. Every plane has a "pet quota." If there are already six cats in the cabin, your dog is out of luck. Also, they don’t take pets on certain aircraft like the Boeing 737 for international routes—something about the heating or space, who knows—but just check the plane model.

Who’s Actually Allowed?

Korean Air is picky about the guest list. You’ve got:

• Dogs (the usual suspects).

• Cats (obviously).

• Pet Birds (if you're that person).

If you’re trying to fly with a hamster, a rabbit, or a snake? Forget it. They won't touch 'em.

Flying in the Cabin: The Under-Seat Reality

If your pet is tiny—and I mean tiny—they can stay with you. The magic number here is 7kg (about 15 lbs). That is the weight of the pet plus the carrier. If your pug has been hitting the treats too hard and hits 7.1kg, they might make him go in the hold. Ugh.

Carrier Specs (The "Will it Fit?" Game)

This is where people mess up.

• Hard Carriers: Max height is 19cm (7.5 inches). That’s tiny.

• Soft Carriers: You get a bit more wiggle room—up to 25cm (10 inches)—but only because they can be "squished" down to fit under the seat.

• Width/Length: Keep it around 32cm x 45cm.

One pet per person in the cabin. No exceptions. And don't you dare think about taking them out of the bag mid-flight for a "quick cuddle." The flight attendants will be on you in seconds. It’s for safety (and allergies), but yeah, it’s tough when they’re whimpering.

The Cargo Hold: For the Big Guys

If your dog is a "real" size (over 7kg but under 45kg/99 lbs including the crate), they’re going down below. I know, I know—the thought of your baby in the cargo hold is stressful. But Korean Air’s hold is pressurized and temperature-controlled.

Important Age Check

• Cabin: At least 8 weeks old.

• Cargo: At least 16 weeks old.

Don't try to sneak a puppy on too early. They check the papers. Speaking of papers...

The Paperwork Nightmare (Don't Forget the Rabies Shot!)

You need a health certificate. Not one from three years ago—usually within 10 days of travel. And rabies vaccinations? They need to be done at least 30 days before you fly.

If you’re heading into Korea, you need a microchip (ISO compliant, don't ask) and a rabies antibody test (titer test). If you show up at Incheon without that titer test result, your pet is going into quarantine. And quarantine is expensive, lonely, and just... no. Avoid it.

Pro Tip: Keep a folder. A physical, plastic, waterproof folder. Digital is great until your phone dies or the Wi-Fi at the check-in desk is spotty.

What’s it Going to Cost? (The Fees)

It ain't cheap. The Korean Air Pet Policy fees are separate from your baggage allowance.

Note: These prices fluctuate based on exchange rates and specific zones, but this is the ballpark.

Snub-Nosed Breeds: The "Breathability" Issue

If you have a Bulldog, a Pug, a Persian cat, or anything with a "squished" face—pay attention. These guys have a hard time breathing at high altitudes.

• Cabin: Usually okay.

• Cargo: Strictly prohibited on many routes, especially during summer (June to September).

It’s a safety thing. They don't want to risk a respiratory emergency mid-air where nobody can help. If you have a brachycephalic breed, your only real option is often keeping them under 7kg and bringing them in the cabin.

Service Dogs: The Exception to the Rules

Fully trained service dogs (not "emotional support" animals—they changed the rules on those a few years back) fly for free and in the cabin. They don't need a crate, but they do need a harness. You’ll need to submit the U.S. DOT Service Animal Air Transportation Form at least 48 hours before the flight if you're US-bound.

SkyPets: Get Some Kickbacks

If you're going to do this often, sign up for SkyPets. It’s like a frequent flyer program but for your cat. You collect "stamps" for every flight.

• 1 domestic flight = 1 stamp.

• 1 international flight = 2 stamps.

• Accumulate enough, and you get discounts or even free pet travel. It’s one of the few "nice" things about the process.

Final Random Bits of Advice

• No Sedation: Don't drug your pet. Most airlines (including this one) hate it because it affects how the animal handles pressure changes.

• Absorbent Pads: Line the bottom of the carrier. Even the most well-trained dog might have an "oops" when the engines roar.

• Label Everything: Tape your name, flight number, and phone number (with country code!) all over that crate.

Traveling with pets is exhausting. It’s expensive, stressful, and involves way too much math regarding centimeters and kilograms. But seeing them wag their tail when you finally hit the arrivals hall? Totally worth the drama.
