Flying with your cat requires a carrier that meets airline under-seat dimensions, keeps your cat secure and comfortable, and passes TSA screening without drama. Here's what to look for and what actually works.

  • Cat must remain in the carrier for the entire flight
  • Most airlines charge a pet fee ($95–$150 each way)

What to Look For

TSA Screening Tips

  • Your cat must come out of the carrier and be held while the carrier goes through the X-ray machine
  • Have your cat in a harness under their carrier so you can hold them securely during screening — see: Best Cat Harnesses for Outdoor Adventures
  • Request a private screening room if your cat is anxious
  • Arrive early — TSA screening with a cat takes longer than expected
  • Keep treats accessible in your pocket, not in the carrier bag
