Flying with Your Pet on Delta Air Lines
I've made the journey from Morocco to France with rescue dogs more times than I can count. Each crossing taught me something new about what pets need to feel safe in the air. Delta Air Lines welcomes cats and dogs in the cabin, and they also offer cargo options for larger animals. But the rules are specific, and getting them right means the difference between a smooth flight and a stressful scramble at the airport.
This guide covers everything Delta requires—from carrier dimensions to health certificates. Whether you're flying with a rescue like my beloved Tafoukt or a purebred companion, these details matter.
Can Your Pet Fly in the Cabin?
Yes. Both cats and dogs are allowed in Delta's cabin, provided they meet weight and size requirements. This is the most comfortable option for your pet—they stay with you, in familiar surroundings, rather than in cargo.
Cabin eligibility:
- Cats: Allowed in cabin
- Dogs: Allowed in cabin
- Service dogs: Travel at handler's feet (exempt from carrier requirement)
- Minimum age: 8 weeks old and fully weaned
One important note: you must book your pet in advance. You cannot simply arrive at the airport with a carrier and expect to board. Delta limits the number of pets per flight, so early booking is essential. Aim to book at least 24 hours ahead for dogs.
Cabin Carrier Requirements
Your carrier is your pet's home during flight. Delta requires soft-sided carriers that fit under the seat in front of you. Here are the exact dimensions:
Maximum carrier size (pet + carrier combined):
- Length: 46 cm (18 inches)
- Width: 28 cm (11 inches)
- Height: 28 cm (11 inches)
- Combined weight (pet + carrier): 9 kg (approximately 20 lbs)
This is tight. If your dog or cat weighs more than 4–5 kg, the carrier itself will be minimal. I learned this the hard way with Tafoukt—she's a 20 kg Border Collie mix, so cabin travel isn't an option for her. But for smaller rescues and purebreds, it works beautifully.
What your carrier must have:
- Soft-sided construction (hard-sided carriers don't fit under seats)
- Mesh ventilation on multiple sides for airflow
- Absorbent liner or mat inside to manage accidents
- Secure closure that won't pop open during turbulence
The absorbent liner is non-negotiable. Pets get anxious in the air, and accidents happen. A good mat protects both your pet's dignity and the airline's upholstery.
Cabin Pet Fee
Cost: $125 USD per pet, one way
This is a flat fee, not based on distance. If you're flying round-trip, budget $250. It's a reasonable price for keeping your companion close during flight.
Cargo and Checked Baggage Options
For larger dogs like Tafoukt, cargo is the only option. Delta accepts pets in cargo, but the requirements are stricter and the experience is different—your pet travels in the cargo hold, not the cabin.
Cargo eligibility:
- Minimum age: 10 weeks old and fully weaned
- Hard-sided, IATA-compliant crate required (not soft-sided)
- Attached water bowl that can be filled from outside
- Ventilation openings on at least three sides
- Absorbent liner inside
- "Live Animals" labels with orientation arrows on all sides
Temperature restrictions:
- Cold embargo: Below -6.7°C (20°F)
- Heat embargo: Above 29.4°C (85°F)
These embargoes exist because cargo holds aren't climate-controlled like cabins. If temperatures at your origin or destination airport exceed these thresholds, Delta may refuse to transport your pet. Plan travel for mild seasons if your pet is flying cargo. I always avoid summer and winter for this reason.
Checked baggage follows similar rules to cargo—hard-sided crate, water bowl, ventilation, and labels required.
Health Certificates & Documentation
This is non-negotiable. You must have a vet-issued health certificate, even if Delta's website doesn't explicitly mention it. It will be checked at the airport, and without it, your pet won't board.
Health certificate requirements:
- Issued by a licensed veterinarian
- Valid for 10 days from issue date (some destinations require 7 days—check your destination)
- Must be dated as close to departure as possible
- Should confirm your pet is healthy and fit to fly
Schedule your vet appointment 2–3 weeks before travel. This gives you time to address any health issues and get the certificate issued within the valid window. Don't wait until the last minute.
Breed Restrictions: Brachycephalic Breeds
Most airlines, including Delta, restrict brachycephalic (snub-nosed) breeds due to respiratory risks during flight. These breeds struggle to breathe in pressurized cabins.
Commonly restricted breeds include:
- Bulldogs (all types: English, French, American)
- Pugs (all types)
- Boxers
- Boston Terriers
- Shih Tzus
- Pekingese
- Persians and Exotic Shorthairs (cats)
- Chow Chows
- Shar Peis
If your pet is on this list, contact Delta directly before booking. Some airlines make exceptions with veterinary acclimation certificates, but policies vary. Don't assume your breed is allowed.
What About Sedation?
Do not sedate your pet for air travel. IATA (International Air Transport Association) regulations prohibit sedation during flight because a sedated animal cannot maintain equilibrium or respond to emergencies. This applies to all commercial airlines worldwide. If your vet or the airline suggests sedation, get a second opinion.
Pregnant Animals & Animals in Heat
Delta does not accept visibly pregnant animals for travel due to health risks during flight. If your pet is pregnant, confirm directly with Delta before booking—don't assume it's possible.
Animals in heat: We're still verifying Delta's specific policy on this. Contact them directly to confirm.

What You Need to Do: Actionable Checklist
- 3–4 weeks before travel: Schedule a vet appointment for a health certificate. Confirm your pet is fit to fly.
- 3 weeks before: Check if your breed is brachycephalic-restricted. If so, contact Delta for clarification.
- 2 weeks before: Measure your pet and any carrier you're considering. Verify it meets Delta's dimensions.
- 2 weeks before: If flying cargo, order an IATA-compliant hard-sided crate. Soft-sided won't work.
- 1 week before: Book your pet with Delta (if not already done). Confirm the booking.
- 10 days before: Get your health certificate from your vet. Verify the date is within the 10-day window.
- 1 week before: Prepare your carrier with absorbent liners. For cargo, ensure water bowl is attached and "Live Animals" labels are applied.
- 3 days before: Acclimate your pet to the carrier. Short trips in the car help.
- Day of travel: Arrive early. Have your health certificate ready. Confirm your pet's booking at check-in.
A Broader Perspective on Pet Travel
When I rescue dogs from shelters in Morocco, I think about how international pet travel infrastructure benefits not just purebreds, but animals in need. Tafoukt came from a shelter where she had no future. Today, she travels with me across Europe because airlines have systems in place. Those same systems—health certificates, carrier standards, temperature controls—exist to protect all animals, whether they're rescues or registered pedigrees.
If you're considering adopting internationally or relocating a rescue, know that it's possible. The rules are strict because they work. Follow them carefully, and your pet will arrive safely.
