I didn't pay first two months. But thirth and fourth months I paid like this. I guess, thirth months I am in 5 different cities. It's same with first and second months. My based city (IST) have big airport and the others are smaller.
I woke up today and I saw, my gates decreased from 5 to 2 in Istanbul. After that I have started to pay extra 2 millions.
I'm waiting next month earnings now. I'll look differencies.
