Can I buy my dog a plane ticket?
Most airlines only let travelers carry on small dogs and cats, and you'll generally have to pay for the privilege of storing them under the seat in front of you. If you want more space, some airlines let you buy an extra seat that you might be able to use to place your pet's carrier on during the flight.

Typically, they need to weigh 20 lbs. or less, following the airline's carry-on luggage weight restriction. If you have a large dog, you can still take them on the plane but not in the cabin. Depending on how large your dog is, they could travel as checked baggage or as cargo.
