Is it safe to travel to Moscow at the end of April? How about Aeroflot?

You need to wear a thin cotton-padded jacket or a single coat. The temperature can be between 0 and 20 degrees. Personally feel safe, it is best to travel together. Whether flying is safe or not depends on luck. After all, it is extremely unlikely. Just choose the one with high cost performance. I take Hainan Airlines more often, Russian Airlines is cheaper, and Air China is the most expensive.
