"When you arrive at the airport, you will need to visit the Special Service Counter to check-in with your pet. At check-in, a Delta agent will ensure your pet and kennel meet the necessary requirements for your trip and collect the required pet fee. Remember to allow extra time at check-in for us to ensure your pet is ready for take-off.
