Air carriers have their own regulations concerning a (1) a certificate of health from a USDA accredited veterinarian within 10 days of any travel date; (2) a summer pet embargo when temperatures are forecasted to be above 85F / 29.5 C at any point on the itinerary (origin, transfer, or final destination); 75F / 24C for snub - nose animals; (3) limits on the number of service animals and
small pets allowed as carry - on luggage in
cabin on a flight, (4) specific air kennel
dimensions and strength to ensure the comfort and safety of the animal, and others.
IATA said that there has been too much confusion about the proposal (which it calls
Cabin OK)-- particularly by media reports that made it sound like the standard would be mandatory and that travelers would have to rush out and buy new carry - on luggage to meet the
smaller dimensions.
