Thank you for the answer. I phoned their international customer care number and after short chat operator said that only chance for upgrade would be airport one. I also spoke with my local office and they say that I should call them few times before departure in case something will free up. Expert flyer shows seats available and cabin is about 50% full, for reference economy is almost empty.
