1925, the US Congress passes the new Air Mail Act also known as the Kelly Act. The Postmaster General will now contract commercial airline companies to carry mail.

Step into the shoes of an aviation tycoon and manage one of these companies competing for the contracts to establish and operate the first air mail service. Grab the incentives offered by the government by plotting the most efficient routes and developing the technology that will allow you to build the most autonomous and reliable models. Whoever can make the most profit for their company will win. Get ready for Air Mail to take off!
