How to Choose the Best Airline for Flying with a Dog (Step-by-Step)

Why your airline choice matters

Not all airlines treat pets the same, and the differences can be significant. Some allow small dogs in the cabin with clear, straightforward rules, while others rely heavily on cargo transport with stricter limitations.

Choosing the right airline affects:

• Whether your dog flies in-cabin or in cargo
• The likelihood of delays or denied boarding
• Your dog’s comfort and safety during travel

Step 1: Decide how your dog will fly

Before comparing airlines, you first need to decide how your dog will travel. Cabin and cargo have completely different requirements, restrictions, and risks. Most small dogs can fly in the cabin if they meet size and carrier limits. Larger dogs typically need to travel in cargo.

Step 2: Check route availability

Not all airlines allow pets on every route. Some countries have restrictions, and certain aircraft types don’t support pet travel at all. Even if an airline allows pets, availability can vary depending on:

• Departure and arrival country
• Layovers and connections
• Aircraft type

To understand how this plays out during travel, see the airport process step-by-step guide.

Step 3: Compare key airline factors

Not all “pet-friendly” airlines are equal. The differences often come down to a few key factors that directly impact your dog’s safety and your overall experience.

Pet Policy Clarity

The best airlines clearly explain their pet policies, including size limits, fees, and restrictions. Others are vague, which can lead to issues at check-in.

Route Availability

Not all airlines allow dogs on every route. Some countries also restrict pet entry depending on the airline. Always confirm both the departure country and arrival country rules as well as transit airport policies. Even if an airline allows pets, availability can vary depending on the route, aircraft, and connection points.

Temperature Restrictions

Many airlines will not transport pets if temperatures are too hot or too cold at any point in the journey. This is one of the most common reasons dogs are denied boarding.

Breed Restrictions

Certain breeds (especially brachycephalic dogs like pugs or bulldogs) may be restricted due to breathing risks.

Cost

Pet fees can vary significantly, in-cabin fees are typically $75 – $300 USD and cargo can range from $200 to $1000+ USD. Higher cost does not always translate into better service, but ultra-cheap options can be risky.

Step 4: Compare actual airlines

Once you understand what to look for, the next step is comparing real airline options. This will help you narrow down airlines based on your route, your dog’s size, and your travel style.

Red flags to avoid

Avoid airlines that:

• Have unclear or inconsistent pet policies
• Regularly change rules without notice
• Don’t allow pets on common international routes
• Have poor customer support when handling pet travel

If something feels uncertain before booking, it will likely be worse on travel day.

Pro tips for choosing the right airline

• Book early—pet spots fill up quickly
• Choose direct flights whenever possible
• Avoid extreme weather seasons if using cargo
• Double-check all requirements 1–2 weeks before departure

Flying with a service dog

Traveling with a service dog follows a different set of rules than standard pet travel. In many cases, service dogs are allowed to fly in the cabin regardless of size, but airlines have become more strict in recent years—especially on international routes.

Requirements can include:

• Advance notice before your flight
• Airline-specific forms and documentation
• Behavior and training standards

Policies vary significantly between airlines and countries, so it’s important to confirm requirements directly with your airline before booking. If you’re traveling with a service dog, choosing the right airline becomes even more important due to these differences.

My experience flying with a dog

I have peronally flown internationally with Beckham across multiple countries, airlines, and airport systems. What I have learned is the airline you choose makes a huge difference. Clear communication, consistent policies, and the familiarity of staff with pet travel matter just as much as the official rules.

In my experience:

• Airlines with clear, well-documented pet policies tend to have a smoother check-in
• Direct flights, or breaking long journeys into two flights, significantly reduces stress for your dog
• Calling ahead to confirm details will prevent last-minute surprises at the airport

Final thoughts

Choosing the right airline comes down to matching your dog’s needs with the airline’s policies, routes, and reliability. If you’re still unsure, step back and look at the full travel process—from planning to arrival—to make the best decision.
