Why airlines tickets twice as expensive now?

[Moses]

I want to go in October. Butairline tickets are now about twice as expensive. 1400 EUR is about the cheapest for a direct flight. Used to be around 700-800.

Is this the petrol prices or are there other factors in play ?

Passengers pay for ban of Russian airlines in EU.

Russian carriers have been barred from almost all of Europe’s airspace as part of sanctions imposed by the European Union. Russia’s government is responding with bans for airlines from supporting sanctions countries, forcing European carriers to cancel flights and reroute their networks to parts of Asia.
