I posted this same question on the Russia based airlines forum a week ago and have only received one reply, which didn't really provide an answer.
So as my question has an Avios link I thought I would post it here.

I am looking to purchase an internal flight, Moscow to Sochi, using Avios (dependent on cash price of ticket). Does anyone know if Avios availability shows as soon as ticket sales start?

And does anyone know how far in advance S7 start selling tickets?

At present if I look to buy cash or Avios seats I can't seem to get anything beyond March 24th 2018.

I asked S7 and was informed tickets went on sale 6 months ahead of the date of the flight, but they are already selling for March, which is 8 months away!
Their calendar doesn't appear to roll. Its been stuck at March 24th for a couple of weeks now.

Any help or advice would be much appreciated.
