Flyer, I don’t think the supersonic plane is actually going to happen.
A large passenger jet realistically costs over $15 billion to get to the production stage, and profits are so thin this requires massive gov subsidies to even hit breakeven.
What the market really wants is cheap, even if is a little slower and more crowded. The other big trend is the decline of hub and spoke.
Personally I don’t mind the normal transatlantic flight time. Have a meal, watch a movie, take a nap, and I’m there.
Now my two transpacific flights I’d pay extra to shorten. All four of my Transpacific legs were LAX to Taipei on China Air.
