On British Airways, pets are not accepted in the aircraft cabin. Pets must be booked to travel with IAG World Cargo, and they will be carried in the aircraft hold. OpenSkies is a BA subsidiary that operates direct flights between Paris and New York. If your cat or dog weighs less than 6kg (13.2lb) they can travel with you in Eco (economy) and Prem Plus (premium economy). British Airways is part of the Pet Travel Scheme which allows cats and dogs to travel between some countries and UK airports avoiding quarantine.
