IATA issued new operational guidance on 15 July 2026 to standardize in-cabin pet travel across booking, check-in, boarding, onboard handling, and arrival, addressing persistent inconsistencies among operators[1]. The In-Cabin Operational Guidelines provide recommended procedures for every journey stage, delivering a predictable experience while maintaining safety, animal welfare, and operational efficiency[1]. This guidance complements the 52nd edition of IATA Live Animals Regulations effective 1 January 2026, which sets global safety standards but does not cover passenger-facing operational workflows[1][2]. Airlines can adopt the unified framework to streamline training, reduce check-in delays, and improve the onboard experience, though adoption remains voluntary rather than mandatory[1]. Technical requirements such as weight limits and carrier dimensions remain defined by individual airline policies or LAR, not this guidance[1][2].
