Hi this game is great and it should have more airports to build. I think that your old airport should be saved when moving on to another airport so you could go back and upgrade and manage your old airports. The reason for four stars is when I go to the 3rd airport, there should be more passengers dropped off per minute at max upgrades and more gates and planes and make the airport have multiple terminals Togo back and forth to terminals. The upgrades at the check in at airport 3 only go up to 150passengers/min and it stops with further upgrades. Another r reason is at the 3rd airport, I barely play for even 5 MINUTES and then the game kicks me out and I have to start the game all over again. If you could fix these and make improvements, I really appreciate it since this game has potential to grow.
