This is correct, as described in my post #11 above. The income for Aeroflot last year from them was about USD 200m, which was significantly more than Aeroflot's overall profit for the year. Cancelling the fees, or not, has become embroiled with the EU's threat to start charging airlines silly "pollution fees" based on how much fuel they use - if the EU starts actually levying these then you can wave goodbye to the Russian overflight fees being ended.
