Hello, my travel with S7 Airlines IST Terminal was excellent! The terminal is well signed so the S7 check-in desks were easy to find. The airport staff were friendly and had good English, which made a big difference. Security procedures were well-organized and did not seem stressful. I located a nice coffee bar close to the gate, and there were sufficient charging points for devices. Clean bathrooms and cozy seating contributed to the good atmosphere. I was impressed by how smooth everything was. S7 at certainly provided a trouble-free beginning to my journey.
