Will we ever fly supersonically over land?

I don’t lose 6 hours on a typical airline trip. Domestic, I tend to arrive around an hour before gate close time. International from the US, about 90 minutes. For a train, I’d still plan on a 30 minute safety buffer (to protect against en route delays to the station). Add another 30 minutes over the train for boarding, push, and taxi. So, I’m probably giving up an hour plus/minus however closer the train station is vs the airport.

Arriving, baggage claim rarely takes more than 30 minutes. (Delta “guarantees” 20 minutes on domestic flights.) With no checked bags, it’s the 10 minute walk through the airport and then plus/minus ground transport differences vs the train.

I can’t imagine that most people are spotting the train a 6 hour head-start, unless the live upstairs from the train station and are extremely nervous about missing their flight.

Of course it depends, but train stations tend to be in the center of a city, so you start from the center of A and arrive to the center of B.

With planes, airports are way off the city centre, I think that there are few airports (here in Europe) serving large cities that can be reached in less than 1 hour from the city centre, and that applies to both A and B, to this you add, unless you use a private means of transportation (car-taxi), a half an hour for the timetable of the bus or train you need to take to/from the airport, as it won't necessarily be synchronized with your flight departure/arrival.

That kinda implies you leave and go to the city centre each time, which might not be the case. Living next to a major train station is usually very expensive. If you're visiting family in the suburbs, you might be closer to the airport than the city centre (or be "unlucky" and have the airport on the other side of the city). It sounds pretty situational to me.

The numbers on my comment are for 3 hours, not 6. (Yeah, the text is not very clear on that.)
