In LiveFlight there are red areas showing the dimensions for each region.
I roughly took the dimensions of Hawaii’s map (taking care of ratio) and recreated the area onto Nepal and Bangladesh. Here is the result:
This means that roughly, the airports of:
-VNKT (Katmandu-Tribhuvan Intl.)
-VGHS (Bangladesh-Shahjalal Intl.)
-VQPR (Thimphu-Paro Intl.)
Could be fitted into the new region.
I think it would be a great addition, with lovely imagery and challenging airports.
