“The Standard Edition will cost $59.99, and will let you fly 20 different planes, and land (and takeoff) from 30 different airports. The Deluxe Edition ($89.99) will include 25 aircraft and 35 airports, and the Premium Deluxe Edition ($119.99) will include 35 aircraft and 35 airports.”
You can actually fly to every single airport in the world, (takeoff and land). There are even 37,000 of the world airports that have been manually edited so that they are more detailed/realistic. These 30 (standard), 35 (deluxe), and 40 (premium edition) airports are just handcrafted international airports that are even more detailed than all of the others. The standard edition will still have these same 15 airports as the premium edition does, but they just won’t be the more detailed/realistic versions .
