Thank you for contacting support.
Unfortunately purchases made through the App Store or Google PlayStore do not transfer to the opposing App Store, whether Apple or Android. Each App Store has control over their own purchases, not allowing them to be honored by the opposite store, much like a game for Xbox would not be recognized by PlayStation.
That being said, if you do have a Pro subscription currently it will transfer that to your new account simply by logging in via Facebook or Google depending on which you used on your previous device. Those with Pro will also have all regions and aircraft transferred because those items are part of the Pro subscription.
Important Note: Aircraft and Regions will not transfer between different operating systems. Only those with the Pro subscription will have access to all IAPs for the duration of their subscription regardless of operating system.
Thank you for allowing me to assist you today and we apologize for any inconvenience.
