I compared S7's pet rules line by line before letting anyone book, and the headline that mattered most was the cabin weight cap of 10 kg. That single number decides whether your dog rides beside you or below deck. Luna, naturally, disapproves of taxiing regardless. If you like knowing the rules before the airport, this breakdown was built for exactly that kind of preparation.
S7 Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Health & documents
S7 requires the pet reservation to be made at least 24 hours before departure. Book the pet as a separate reservation the moment the passenger ticket is confirmed. Do not wait for check-in to add the animal. Missing the 24-hour window means the pet can be refused at the gate. Confirm the reservation is recorded against the specific flight.
Frequently asked
- What if my flight is delayed past my health certificate validity?
- If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
- What happens if I forget a document?
- At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
Rules shift by route, aircraft, and connection, and a printed policy from last year rarely survives contact with reality. Before you commit to S7, build a personalized plan for your exact trip so the weight cap, booking deadline, and paperwork all line up. I keep a printed copy in three places now, and Luna supervises. Let Pawgo's plan-builder assemble yours before you buy the ticket.
