A lot of carriers did the same. Singapore and Cathay for example. I am thankful that SU extended my status, builds goodwill in my opinion.
I look forward to returning when all of this is over. My Russian visa expired - no chance of getting that renewed in this climate. So I can't even go anywhere SU flies, much less stopover.
There was talk about extending the E-visa schchemes in the Far East and LED to the whole of Russia in 2021, I hope that will still happen.
