Size Specifications by Major Airlines
When selecting airline approved pet carriers for in-cabin travel, you’ll need to adhere to specific size requirements that vary by airline. United, American Airlines, and Delta all maintain consistent dimensions of 18 inches L x 11 inches W x 11 inches H. Southwest offers slightly more generous measurements at 18.5 inches L x 13.5 inches W x 8.5 inches H. JetBlue provides the most width at 17 inches L x 12.5 inches W x 8.5 inches H, while Alaska Airlines has the most restrictive dimensions at 17 inches L x 11 inches W x 9.5 inches H.

| United | 18″ | 11″ | 11″ |
| American Airlines | 18″ | 11″ | 11″ |
| Delta | 18″ | 11″ | 11″ |

Weight Restrictions and Airlines with No Weight Limits
Your pet carrier weight requirements differ significantly across airlines. JetBlue enforces a 20-pound limit that includes both your pet and the carrier weight combined. However, American Airlines, Delta, Alaska Airlines, and United maintain no weight restrictions for in-cabin pet travel, giving you more flexibility when choosing pet travel carriers for larger animals within size constraints.
In-Cabin vs Cargo Travel Requirements
For in-cabin travel, your pet must fit comfortably inside the carrier and be able to stand up and lay down naturally. The carrier will be placed under the seat in front of you, typically requiring an additional fee of approximately $125 one-way. Your pet must remain in the carrier throughout the flight. When shipping pets as checked baggage or cargo, you’ll need more robust carriers that can withstand handling and temperature variations.
IATA Compliance Standards for International Travel
For international pet travel or cargo shipment, your carrier must comply with International Air Transport Association (IATA) guidelines. These standards ensure your pet’s safety during longer journeys and varying transport conditions. IATA-compliant carriers feature reinforced construction, proper ventilation, and secure locking mechanisms. Always verify your airline’s specific pet policy page for maximum carrier measurements and requirements, as regulations can change frequently.
