Pets in the Cabin
S7 Airline welcomes dogs, cats, and household birds to travel in the cabin on certain routes. Fido, Fluffy, and Polly must have a combined weight with their carriers less than 17 lbs (8 kg) to qualify for travel in the cabin. Fees for this service are based on S7 excess baggage fees and vary by destination (e.g. Moscow to Samara for 115 RUB per kg and Moscow to Frankfurt for 8 EUR per kg).

In the cargo hold, animals will travel in an area of the aircraft with a similar temperature and pressure to the cabin. Fees vary for each destination, weight of the animal, and the size of their carrier.
