The upgrade is nice, but having to pay higher than the "on sale price" again for what the airport should have been to start is disappointing.
Main complaint is poor attention was paid to gate parking. All real life aerial views, including MSFS loading screen show In real life gates 9 & 10 are set aside for multiple parking spots of "GA level" inter-island airlines. This is not modeled (Although there is a "gate 11" placard). So if you are wanting to fly a Cessna level commuter you park at a "big gate", and small AI will not look right. There are also two spots (Ramp 29 and Parking 30) that are right in the middle of the tank farm at the south end of the airport.
The terminal interior is fair, exterior is good except for the terminal main / flat roof is low res compared to the rest of it.
