The International Air Transport Association (IATA) has introduced a comprehensive set of global guidelines designed to streamline the air travel experience for passengers flying with cats and dogs. As the popularity of traveling with pets continues to surge, the industry has suffered from fragmented and confusing policies. By standardizing procedures—ranging from the initial booking and check-in process to boarding and in-flight handling—IATA aims to eliminate inconsistencies across different airlines. Under these new rules, pets must be kept in carriers that meet the "CR1" standard, ensuring the animal has enough space to stand, turn around, and lie down comfortably. Passengers are advised to book at least 48 to 72 hours in advance and will now use a universal "PETC" booking code, though travelers may still need to coordinate directly with airlines due to limitations on some third-party booking sites.

To ensure safety and animal welfare, the new framework mandates stricter check-in procedures, including formal health inspections and verification of vaccination records. Airlines are now empowered—and expected—to deny boarding if a pet appears distressed or if the carrier fails to meet safety requirements. Once on board, pets must remain secured in their containers for the duration of the flight, including during takeoff and landing. The guidelines also address logistical challenges, such as flight delays and layovers, requiring airlines to provide better information regarding pet relief areas and contingency plans for animal comfort during travel disruptions. While these rules provide a much-needed benchmark, IATA clarified that they are meant to supplement, not override, individual airline policies, serving primarily to reduce service disputes and improve the consistency of the passenger experience.
