Answer by Alexander for Why 1st and 2nd class but not fast or slow airplanes?
At the moment, planes travel at around mach .75 to .95; which is a tradeoff between speed and fuel consumption.While it is possible to produce faster airplanes, no one does, because significantly...

There is a faster option - it's a case of looking at total travel time - door to door. In which case private jet is faster.It goes when you want it to - no waiting for the 747 or A380 to go once a day...

In thinking about it, the 1st, 2nd and 3rd class distinction originally arose in the time of watercraft travel and during those days, there were also significant distinctions in the speed/cost...

Gravity * time aloft.Because a heavier-than-air craft must expend a constant amount of energy just to stay aloft* per unit of time, it maximizes efficiency in a trip of given length by minimizing the...

To offer different rates for different speed of travel the airline would need to add different aircraft types to their fleet, which would increase their cost of doing business dramatically.They'd need...

isn't the cost directly proportional to speed?No.Most fuel can be saved by flying higher because the lower air density reduces parasite drag. Provided the trip is long enough for the saving at altitude...

Providing a fast and a slow "class" for flight tickets would add a lot of overhead to airline operation in many ways - way more than it could be worth it:To have fast and slow flights, one couldUse two...

There is indeed a benefit in flying more slowly, but the aircraft needs to be designed that way to profit from slower speeds. You can see that wing sweep has been slightly reduced in the more modern...

Concorde was built for speed. But it was costly too. People did not like it much. Reality was that they didn't want to get somewhere faster by paying more. People love to pay for luxury though. That is...

The optimal speed of the aircraft is set by the manufacturer. isn't the cost directly proportional to speed?No, any speed above or below the optimal one will lead to sub-optimal performance of the...

Why do airlines separate passengers into 1st and 2nd class but do not offer fast or slow connections? Isn't the biggest cost the kerosene? And isn't the cost directly proportional to speed?
