That taxi doesn't have another 190 seats that can be sold for "cost".
3 Holer, that is true. However, 40 million is 1000 times more than 40 thousand, but the aircraft doesn't have 1000 more seats to sell than the taxi.
So, taking everything else out of the equation, the airfare still should be more than the taxi fare
over the same distance.
Now, if you consider the greater distance of a flight compared to the taxi fare to the airport, along with all the other expenses, common sense would dictate that the airfares be much higher than they are. Particularly when some of the other expenses include 2 drivers, not one; 3 or more flight attendants; engineers in attendance for every departure & arrival; catering; baggage handlers; checkin staff; security; ATC; much larger training costs; etc - the list goes on.
Any individual who gives it some thought would have to concede that if you want to travel with the speed, comfort & safety of air travel, you need to pay a little more.
Come to think of it, how come all the people crapping on about how airfares need to be lower, aren't also fighting for lower taxi, bus & train fares?
