Depending on animal breed and size, they can travel as a carry-on or be transported through American Airlines Cargo. Carry-on pets are limited to cats and dogs that meet the size, age and destination requirements.

Yes, airlines still ship dogs in 2026, but the options have become much more restricted and expensive than in previous decades. Most major airlines now categorize pet travel into three modes: In-Cabin (for very small dogs who fit under the seat), Checked Baggage (for medium dogs on the same flight as the owner), and Manifest Cargo (for large dogs or those traveling alone). Following several high-profile safety incidents, many U.S. carriers like United and Delta have largely eliminated the "Checked Baggage" option, requiring larger dogs to fly via their specialized cargo divisions (like Delta Cargo), which can cost between $500 and $2,500. There are also strict "temperature embargoes"; if it is too hot or too cold at any point in the journey, the dog will not be allowed to fly. Furthermore, "brachycephalic" (short-nosed) breeds like Pugs or Bulldogs are banned from the cargo hold by almost all airlines due to respiratory risks. In 2026, many pet owners are turning to "pet-only" boutique airlines or private charters to avoid the stress and safety concerns of traditional cargo shipping.
