For millions of travelers, pets aren’t just animals—they’re family. According to a recent Pew Research Center survey, 97 percent of American pet owners consider their pets integral members of the household.
So it’s no surprise that when planning vacations or trips, many people want to bring their furry companions along. But traveling with pets isn’t always simple.
Airline regulations, size restrictions, and limited cabin space can make the logistics daunting. Fortunately, some airlines are doing more to accommodate pets, making it easier for owners to travel with their four-legged friends.
Recently, Years, a dog nutrition and care organization, released a detailed report analyzing airline pet policies across Europe. Their findings reveal which carriers are best for pet travelers, what rules apply, and tips to keep dogs calm and happy during flights.
Here’s what pet owners need to know before booking their next journey.
Understanding Cabin Pet Policies
Most airlines follow strict rules for pets traveling in the cabin. The key requirements are surprisingly consistent across carriers:
- Dogs must weigh around eight kilograms (17.5 pounds) or less, including their carrier.
- Pets must remain under the seat in front of the owner for the entire flight.
- Space for cabin pets is limited, so advance booking is essential.
- Some airlines require pets to be healthy, vaccinated, and well-behaved.
While these guidelines sound restrictive, they help ensure safety, comfort, and hygiene for all passengers. If your dog meets these conditions, they’ll likely be welcome on some of the most pet-friendly airlines in the world.
Top Airlines for Pets in Europe
According to Years’ report, these carriers consistently offer the best conditions for dogs traveling in the cabin, as flagged by Travel and Leisure:
- KLM Royal Dutch Airlines – Known for excellent pet support and clear policies.
- Lufthansa – Offers both in-cabin and cargo pet travel, with professional handling.
- Air France – Provides a smooth experience for small pets traveling in Europe.
- Vueling – Budget-friendly options without compromising pet care.
- Aegean Airlines – Recognized for attentive service to pets and owners.
- Iberia – Offers structured pet travel policies and early booking support.
- Air Canada – Supports international travel with comfortable in-cabin pet options.
- Turkish Airlines – Provides detailed guidance and a pet-friendly travel experience.
- Qatar Airways – Offers premium care and safety for small pets onboard.
These airlines not only allow pets in the cabin but also provide clear guidelines, making it easier for owners to plan stress-free travel.
Pet Travel in the U.S.
European carriers aren’t the only airlines accommodating pets. U.S.-based airlines have similarly thoughtful policies for small animals:
- Delta Air Lines allows dogs, cats, and household birds on domestic flights, provided they meet age, health, size, and carrier requirements. A one-way fee is collected at check-in.
- United Airlines and American Airlines have similar guidelines, ensuring that small pets can fly comfortably in a carrier under the seat.
- Pets generally must be at least eight weeks old, in a properly sized carrier, and booked in advance to secure a spot.
Although policies are slightly different between carriers, the general principle remains the same: small, healthy pets traveling in the cabin are welcome—but preparation is key.
Tips for Flying With Dogs
Flying can be stressful for pets. New sights, sounds, and cabin pressure changes can affect both behavior and digestion. Years provides expert tips for pet owners to make flights less stressful for their dogs:
1. Feed Light, Digestible Meals
Before flying, dogs should receive a small, easily digestible meal several hours before departure. Heavy or rich foods can upset the stomach, increasing discomfort and restlessness.
2. Consider Supplements
Adding prebiotics and probiotics can stabilize digestion, while Omega-3 fatty acids may help regulate inflammation and stress responses. A calm gut often equals a calmer dog in flight.
3. Maintain Routine
Dogs thrive on routine, so try to maintain feeding, walking, and play schedules as much as possible before and during travel. Familiar routines reduce anxiety and help pets feel secure.
4. Proper Carrier Use
Your dog’s carrier should be comfortable, well-ventilated, and sized correctly to fit under the seat. Include a familiar blanket or toy to provide comfort and a sense of security.
5. Keep Calm and Relaxed
Your own demeanor affects your pet. Remaining calm, speaking softly, and offering reassurance can help your dog adjust to the new environment.
As Years explains, “Calm digestion often equals a calmer dog. A settled stomach reduces discomfort, restlessness, and excessive panting during flights.” Following these steps can make both the pet and owner experience more enjoyable.

International Pet Travel Considerations and Accessories
For pet owners flying internationally, additional regulations may apply:
- Vaccination Records: Most countries require proof of rabies vaccination.
- Health Certificates: A veterinarian-issued health certificate may be needed within a specific time frame before travel.
- Quarantine Rules: Some destinations require quarantine or microchipping for entry.
- Breed Restrictions: Certain airlines restrict specific dog breeds due to health or safety concerns.
Checking both airline and destination requirements well in advance ensures smooth travel and prevents last-minute complications.
Beyond airline regulations, having the right travel accessories can improve the flying experience:
- Collapsible water bowls for in-flight hydration
- Portable snacks or calming treats approved for dogs
- Absorbent pads or travel mats for comfort and hygiene
- Familiar blankets or toys to reduce anxiety
- Secure and breathable carriers that comply with airline size limits
These small items make a huge difference in maintaining comfort and calm for pets during the trip.
Why Some Airlines Are More Pet-Friendly Than Others
Some airlines prioritize pets more than others because they recognize the increasing demand from travelers who treat pets like family. European airlines, in particular, often provide:
- Flexible cabin policies for small animals
- Pet-friendly boarding procedures
- Staff trained in pet care and handling
Similarly, Gulf carriers like Qatar Airways emphasize in-flight comfort and safety for pets, reflecting a broader trend of accommodating family travelers with animals. These airlines are setting a new standard for what pet-friendly travel should look like.
Planning Your Pet’s Vacation
When booking a flight, pet owners should:
- Check Airline Policies – Review weight limits, fees, and documentation.
- Book Early – Space for cabin pets is limited.
- Prepare the Dog – Adjust diet, practice in-carrier comfort, and maintain routine.
- Pack Essentials – Food, water, bedding, and favorite toys.
- Review Destination Rules – Understand any international entry requirements.
Planning ahead ensures a smooth, stress-free experience for both owner and pet, from check-in to arrival.
Final Thoughts
Traveling with pets doesn’t have to be stressful or complicated. With the right airline, preparation, and travel accessories, both pets and owners can enjoy a safe, comfortable, and memorable journey.
Airlines like KLM, Lufthansa, Air France, Delta, and Qatar Airways are paving the way for pet-friendly travel, recognizing that pets are more than passengers—they’re family.
Following the guidance from years of feeding, calming, and proper preparation, pet parents can make flights more enjoyable for their furry companions.
The goal is simple: arrive at your destination with a happy, healthy, and relaxed pet ready to explore the vacation together.
In 2026, it’s clear that air travel is becoming increasingly accommodating to pets, making it possible for families to keep their four-legged friends by their side on adventures around the world.
