The most dog-friendly airlines tend to have clear pet policies, reasonable fees, good route networks, and onboard teams who are used to helping travelers with small dogs in-cabin. While “best” depends on your dog’s size, your itinerary, and seasonal temperature rules, a few airlines consistently stand out for pet owners.
Alaska Airlines is a longtime favorite for pet parents thanks to straightforward rules, plenty of U.S. routes, and a generally smooth process for reserving a pet spot. JetBlue is also popular for in-cabin travel, with an easy-to-follow pet program and solid transparency around what’s allowed.
Southwest often wins points for its flexible vibe and broad domestic network, though it only allows small vaccinated dogs in the cabin (no cargo option) and requires advance coordination. For larger route maps and international connections, Delta, United, and American can work well—just expect more variation by aircraft and destination, and double-check size limits, documentation, and embargo dates.
Before booking, confirm: (1) whether your dog can fly in-cabin (most comfortable for small dogs), (2) the carrier dimensions and “must fit under the seat” rules, (3) the maximum number of pets per flight (spots can sell out fast), and (4) temperature restrictions that can affect cargo travel. A calm, supportive carrier and a few familiar comfort items can make the cabin experience feel cozy and secure.
Choose flights with fewer connections, avoid extreme heat/cold travel dates, and practice short “carrier time” at home so your dog treats it like a safe den.

Alaska Airlines and JetBlue are commonly praised for clear in-cabin pet policies. Southwest, Delta, United, and American can also be good options depending on route, aircraft, and current restrictions.
Yes, but you’ll need to follow the airline’s pet rules and Spain/EU entry requirements (documentation and timing matter). Confirm requirements well ahead of departure since details can change by origin country.
Bark Air has operated as a dog-focused air travel option, but availability can change by route and season. Check current schedules and service areas before making plans.
