A TSA-approved pet carrier is a carrier that meets Transportation Security Administration (TSA) guidelines for airport security screening. While TSA itself does not set specific size requirements, an airline-approved carrier must fit under the seat in front of you.

Key Features of a TSA-Approved Pet Carrier:
✔ Fits under the seat of the cabin – Must comply with airline size restrictions.
✔ Soft-sided and flexible – Preferred for in-cabin travel, as it can slightly compress.
✔ Well-ventilated – Mesh panels for airflow and visibility.
✔ Secure but accessible – Zippers for easy access during TSA security checks.
✔ Leak-proof bottom – To prevent messes.
✔ Comfortable for pets – Soft interior padding and enough space to move.
