Good but needs content
Overall, the game is fun and with a lack of interruptive ads, it makes for a fun time killer. Depending on how often you play, you could comfortably finish the game in 6 hours - completely levelling up your airport. The game needs more content to compete with other idle games of its type - more airports which would bring more to do. Limited time events and challenges would also bring more to the game. On a very rare note, the ads in the game are actually useful and give you bonuses or cash. They don’t pop up in the middle of the game and don’t seem to be stupidly long either. Overall it’s a good game but lacks in content.
