What is your suggestion?
Hawaiian flies 787-9s from Seattle to Tokyo, Seoul, and likely soon Rome and London on behalf of Alaska Airlines. I suggest making Hawaiian 787-9s available out of Seattle.
How would it work in the game?
Self explanatory. Add Hawaiian to the Seattle dataset of airlines, but only add the 787-9.
Why is this a good idea?
It would add options and realism.
