In pilot airplanes game, you have to unlock free airplane and complete missions for coins
Here, you must control steering the plane midflight from the top down point of view
Try to get lined up properly with the runway as early in the flight as possible in order to avoid either crash or overshoot the runway and having to turn around to attempt another landing.
Use the directional lines that pop up on either the top, bottom, left or right sides of the screen to line up well on runway when landing and taking off the plane
Leave enough room to account for your elevation when going to east or west.
When getting closer to the airport try to slow down as much as possibly and descend as close to the ground as you can.
Try to get closer to the ground that you descend beforehand in that doing so will make easy to judge the position of an east or west runway
Besides that when going slower it will make course corrections easily before you land your plane.
While going to fly your plane it will remind you to go to a different social networking sites such as Facebook, Twitter, Youtube so that just unlock that order or click on a mission in the app store that requires that plane
When the popup prompt you to unlock it, you can simply tap on the button to go to whatever site or the app store for doing so.
Then, without doing the rest of it like sharing, tweeting, rating, etc just go back to the game to unlock a new free planes as a reward to go traveling in the air
