buenos d'as,
I donīt think you should pay anymore than what you have paid so far. We are commercial pilots and we are supposed to be paid for flying, just wait for your chance. Even if you can pay much more it doesnīt mean you are gonna be the first of the queue, some companies only want to make good money from desperate pilots like you or me.
I will not go to the states at least by the moment as the situation now is even worse than before.
Good luck
