How to Fly With a Dog in 2026
Flying with a dog requires more planning than any other form of pet travel. Airline policies vary significantly, the experience can be stressful for dogs, and cargo travel carries documented risks. This guide covers everything from cabin travel rules to minimizing cargo travel risks in 2026.
Step-by-Step Guide
Step 1: Understand the Three Travel Options
Option 1 — Cabin travel (under seat): Only for dogs meeting airline size limits (typically under 15–20 lbs in carrier). Carrier must fit under the seat. Dog stays in carrier throughout the flight. Available on most major domestic carriers for an additional fee ($95–$200). Option 2 — Excess baggage (pressurized cargo): For dogs too large for cabin. The pressurized cargo hold travels in the same temperature-controlled environment as passengers — safer than it sounds. Option 3 — Cargo shipment: Shipped as freight, separate from the passenger cabin. More risk, for specific situations.
Step 2: Research Airline-Specific Pet Policies
Policies vary significantly by carrier. Key variables: size/weight limits for cabin, approved carrier types, breed restrictions (most airlines ban brachycephalic breeds like Bulldogs, Pugs, Boston Terriers due to breathing risk at altitude and temperature sensitivity), route restrictions (weather embargo periods, international requirements), and fees. Check the specific airline’s current pet policy page — policies change frequently.
Step 3: Get a Health Certificate
Most airlines require a veterinary health certificate issued within 10 days of travel for all flights — domestic and international. Contact your vet well in advance. International travel may require additional documentation (USDA-endorsed health certificate, country-specific import permits, rabies titers). Start the international documentation process 2–4 months in advance.
Step 4: Choose a Compliant Carrier
Soft-sided carriers meeting under-seat dimensions for your specific aircraft (dimensions vary by aircraft model — confirm with the airline) are required for cabin travel. Popular options: Sherpa, Petmate, and Sleepypod. Hard-sided IATA-compliant crates are required for checked baggage travel — the crate must be large enough for the dog to stand, turn, and lie down.
Step 5: Prepare Your Dog for the Experience
Acclimate your dog to the carrier weeks before travel: leave it open at home, feed meals inside, take short ‘trips’ to the car. A dog that sees the carrier as a safe place travels far better than one experiencing the carrier for the first time at the airport. Practice security screening motions (removing from carrier, walking through without carrier).
Step 6: Day-of-Flight Management
Exercise your dog thoroughly before the airport. Withhold food for 4 hours before the flight to reduce nausea risk (water is fine). Arrive with extra time — pet check-in adds time to standard check-in. For anxiety: consult your vet about Adaptil spray for the carrier, calming supplements (Zylkene, Solliquin), or prescription medications for severe cases. Do NOT sedate a flying dog with Benadryl or prescription sedatives without vet guidance — sedation is dangerous at altitude for dogs.
Step 7: Minimize Cargo Travel Risks
If cargo travel is unavoidable: fly direct (reduces handling transfers), book morning or evening flights to avoid temperature extremes, use cardboard bedding that’s dry and insulating, attach ice pack to exterior in summer, leave a 48-hour food supply inside, attach clear instructions for watering to crate, and ensure all hardware is secured with zip ties. Check your dog immediately upon arrival — don’t wait for your luggage.

Pro Tips
- Book your dog’s ticket when you book your own — pet cabin spots are limited (typically 1–2 per aircraft section) and sell out.
- Brachycephalic breeds (Bulldogs, Pugs, Boston Terriers, French Bulldogs, Shih Tzus) should not fly in cargo and have reduced cabin oxygen tolerance at altitude — many airlines ban them outright. Know your breed’s restrictions before booking.
- Most airlines stop accepting checked pets when temperatures are forecast above 85°F or below 20°F at any stop — check weather forecasts for all airports on your itinerary.
- Consider pet relocation services (PetRelocation.com) for international moves — they handle all documentation, compliance, and logistics for a fee.
Frequently Asked Questions
Q: Is it safe for dogs to fly in cargo?
A: Pressurized cargo holds travel in the same temperature and pressure as passenger cabins. Risk factors include: extreme temperature weather embargoes, brachycephalic breed respiratory compromise, strenuous cargo conditions during loading/unloading, and the stress of extended isolation. Direct flights, appropriate time of year, and healthy adult dogs have relatively low risk in the pressurized hold.
Q: What size dog can fly in the cabin?
A: Airline cabin size limits vary: most allow dogs under 15–20 lbs (including carrier weight) and carriers fitting under the seat (typical dimensions 18″×11″×11″). Some airlines allow slightly larger. Always confirm the specific airline’s and aircraft’s limits — they differ.
Q: Do airlines allow pit bulls or other restricted breeds?
A: Most airlines do not restrict breeds for cabin travel. For cargo travel, many airlines and countries restrict ‘dangerous breeds’ lists that vary widely. Brachycephalic breeds (Bulldogs, Pugs) are restricted from cargo or air travel entirely on many carriers due to breathing risk. Check your specific airline’s breed policy.
Q: Can I sedate my dog for a flight?
A: The American Veterinary Medical Association advises against sedating flying dogs — sedatives reduce respiratory function, which is already compromised at altitude. Acepromazine (common sedative) is particularly dangerous at altitude. Consult your vet about anxiety management options (Trazodone, Gabapentin) that are safer alternatives.
