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.
What does a U.S. pet passport look like?
Appearance. The pet passport itself comes in multiple forms, sometimes a pink A4 sheet, sometimes a small blue booklet. It contains the microchip or the tattoo number of the animal, the certification that the animal has had a rabies vaccination, and needs to be signed by an officially approved veterinarian.
