I thought about Hawaii also. Rich cities in Northeast Asia might also be a good target: Tokyo, Singapore, Seoul, Shanghai, Beijing to Hawaii might be good targets for weekly (or charter) flights. The tricky part (except Tokyo) would be negotiating supersonic flyover rights. I cannot imagine that Japan would be excited to have regular supersonic flights over their main island from Seoul or Beijing.
Regarding LA<->NYC, I think you could make a dent in that market with an all business class flight that flies slightly less than Mach 1 (0.95 or whatever) and has special security screening and baggage handling. People might be willing to pay 30-50% more compared to business class on a regular flight.
Last: Is there a video game like Theme Park or Railroad Tycoon that allows for the simulation of an airline market? That could be fun.
