Like a lot of people have said, this game has a lot of potential. The repair times, even though they have been improved, should be replaced with a repair shop. So cash earned in game can be spent to fix the plane. The experience needs to be reworked. The ever growing grinding to earn the required experience for the next level is insane. Completing mission don't seem to give any boost to your experience and the amount you gain from flying from one town to the next drags on and on when that is the only way to progress to the next place to complete the next part of the story line. As other have said, increase the market refresh rate. That goes back to just grinding on and on to get the little bit of experience, when the markets are dry there is no point in playing any more and that hurt repeat plays.
