The most terrible airline in the world. I was simply denied entry for no reason. I had transit through Bangkok, according to the rules, transit without visa is allowed as soon as I don't leave the airport and my transit is less than 10 hours, I have been doing that for years. But good luck explaining this simple thing to S7 staff. So I was denied entry the day of the flight. S7 staff was bringing random excuses how I don't hold visa to the last destination (to which I have valid e-visa and it won't be on S7 after Bangkok). The guy was just happy meaningless exuses and told us that our tickets are on sale already. I hate S7 and their staff in Irkusts. I will never take S7 again even if the only alternative is a slow train.

They don't care about their customers. All they want is more money. Disgusting attitude just because they know you don't have a choice.

In 2021 it has been the cheapest airline flying to/from Russia. They have a very decent level of service. And I like their flexibility in booking and adding features. Customer support is always there for you in the chat.

Normally I wouldn't expect much from a budget airline, however I was pleasantly surprised from the moment I stepped into the airplane. The flight attendant Dmitriy approached me straight away offering his assistance in taking care of my hand luggage and escorting me to my seat (and I flew in economy, not business class!). Throughout the journey, the whole crew was very attentive, responsive, patient, polite and friendly. They were helpful and willing to go extra mile with a smile on their faces. I haven't seen this kind of dedication even in Qatar airways, which have been my favourite so far.
The aircraft itself was small, but clean. Nothing remarkable, just standard. But the crew does make the difference, each and every team member. Kudos to them and the management that trains and motivates them properly!
The only disappointing thing was that there was no notification of the flight delay, so I had to spend another 2.5 hours waiting at the airport. However this might have happened due to the fact that I booked my flight via the third party, so I cannot really blame the airline.

I am a US citizen married to a Russian national. We planned a summer 2021 family adventure including 8 people, me my wife and 6 of her Russian relatives. Trip included roundtrip airfare from Saint Petersburg to Novosibirsk. On the return flight my wife's sister and her 17 year old son were denied boarding due to an oversold flight and treated extremely poorly. They were taken for a 1 hour drive far outside the city to cheap accomodations, and the only food provided during their 20 hour delay was a dry sandwich, roll and low end pastry. Nothing to drink. When my wife's sister asked for more food for her son she was denied. What inappropriate behavior by S7 and their employees.
