Usually, no. Even if you’re willing to purchase an extra seat, most airlines don’t allow large dogs to ride in the cabin on their own seat. Typical in-cabin rules require pets to stay inside an airline-approved carrier that fits under the seat in front of you for the entire flight. That’s why larger dogs are most commonly accommodated as checked pets (where permitted) or via specialized pet air travel services—both of which come with extra planning and stricter requirements.
Airlines focus on cabin safety and clear aisles for emergency access. A large dog sitting in a passenger seat can’t be properly restrained by a standard seatbelt, may block evacuation, and can create safety concerns if turbulence hits. For that reason, buying a seat rarely changes the underlying policy.
There are limited exceptions. Trained service dogs are typically allowed in the cabin with their handler (following airline documentation and behavior requirements), and they do not travel inside an under-seat carrier. Emotional support animal policies have largely changed in recent years, and many airlines no longer treat ESAs as service animals.
Start by calling the airline directly and confirming size limits, carrier rules, fees, and temperature restrictions. If cargo travel is the only option, prioritize a sturdy, well-ventilated crate, a calm pre-travel routine, and familiar comfort items (like a soft blanket that smells like home). For layovers and airport time, a supportive travel mat and organized walking bag can make breaks smoother and less stressful.

Sometimes, but typically not in the cabin. Most airlines require dogs that large to fly in cargo (if offered) or through a pet transportation service, with an approved crate and specific health documentation.
It depends on the airline’s under-seat dimensions and your dog’s build. Many 23-pound dogs are too tall or long for under-seat carriers, even if they’re within some weight guidelines.
Most airlines don’t allow pets to occupy a seat, even if you pay for it. In-cabin pets generally must stay in a carrier under the seat, unless they are trained service animals.
