Carry-On. Many airlines allow small dogs to fly with their humans as carry-ons. This means that your carry-on bag is actually your pet carrier, and it gets stored underneath the seat in front of you. Dogs that are able to do this are typically 20 lbs or less, and their carrier must fit below the seat.
Can a 20 pound dog fit under an airplane seat?
Generally, if your dog in its carrier can fit under the seat in front of you, it can go in the cabin. So that means a dog weighing up to about 20 pounds.
How much is it to fly a 20 lb dog?
Generally, airlines charge a pet fee of $100 to $200 each way, but prices will vary depending on where you're traveling and your airline. Check the airline's pet policy before purchasing a ticket to make sure your pet meets the airline's breed and size requirements. If not, the airline won't let them board.
