I've found a few questionable connections missing from my diagram that currently exists in the passenger routes (Note: These connections meet the 250c/r standard)
Passengers_br: Denver, Manhattan
Sold on Grand Vista and New Tokyo under my plan which rules out Denver, Manhattan is a possibility yet creates a two way route.
Passengers: Manhattan, Hamburg,
Sold on Shetland and New London under my plan, no issues on distance/time but does create another two way route.
Passengers_li: New Tokyo, Denver
Sold on Curacao, no problems connecting to New Tokyo but Denver suffers from short travel time (6 mins).
Passengers_rh: Mackinac, Manhattan, Hamburg
Sold on Baden Baden, creates a two way route with Mackinac, no issue with Manhattan however short travel time to Hamburg is questionable (6 mins).
VIP’s: Hawaii, New Berlin
Moved to Denver under my plan, no issue with travel time but creates two way route as both possible connections sell Tourists.
Some of these I removed from my first iteration of diagrams for the reasons listed above however since the connections are already active ingame it would make the idea marginally easier to action. Thoughts?
