Do we have to pay for checked bags?

Plenty of time for that. Just less time for her to be back in her seat disappointed afterwards.

I was on a plane the other day and it really dawned on me that we should be further along with air travel. From the Wright Bros to modern commercial flights of the 60's and 70's, there were massive gains. But now here we are since then and we've still barely advanced in that compative time frame to today. What gives?

You are flying people around the country for the price of a nice dinner. That is pretty impressive.

Do you have any numbers for how much better fuel efficiency would be? Because as you say, even more than the sonic booms, that was the biggest issue facing commercial supersonic flight. Unless it can be dramatically improved, it has zero shot.
The Concorde engines were design finalized at the beginning of 1964, and remained essentially unchanged. The Concorde design itself dates to 1965.
Since then, jet engines alone have gotten about 50% more efficient, and we are far, far better at aerodynamics and packaging than we were then. I would not be surprised to see 75% or more efficiency per passenger mile improvements over Concorde. People forget how old that plane was.

Since the dawn of jet travel, we are about 75-80% more efficient in fuel use per passenger mile. Some of that admittedly though is more tightly packed seating, biggest chunk was from better jet engines.

The problem is air drag. While making it more aerodynamic would help, that plane was already extremely aerodynamic. This is the core problem with supersonic flight, in a single graph:
This is the reason commercial flights currently max out at a very specific speed. Going past that speed has horrific efficiency costs.

Over-simplification of the problem. Dig deeper on what they're doing and get back to me. I assume you have some engineering background and won't be intimidated by their publications?

I don’t; I’m simply a laymen who has read on the issue of supersonic flight over the years. Would you mind enlightening me?
