S7 Airlines carry-on size and weight in 2026
S7 Airlines (Russia, IATA code S7) allows cabin bags up to 55 cm long, 40 cm wide and 23 cm deep; the weight limit is 10 kg.
The dimensions include wheels, handles and outer pockets. A soft bag can usually be squeezed a little, but a hard-shell suitcase cannot lose that extra centimetre — and that is exactly when gate staff ask you to pay.
Fare details: Business class: 2 piece up to 15 kg. Economy: 1 piece up to 10 kg.
