Jet fuel is not that expensive
Estimates for 5 hour flight
A Boeing 767 burns about 9,000 gallons of jet fuel on a cross-country flight. That means American Airlines pays about $34,000 in fuel costs alone for that flight, The airline takes in about $54,000 in total revenue for the average flight from JFK to LAX
$20,000 Dollar profit from full plane size 180 seats
Another estimate (1 to 1.5 hour flights)
According to the calculations, each passenger on board an Airbus A320, which has a capacity of 154, costs the airline $68.50 (£47.06) for the 260-mile journey. The one-hour flight costs the airline an estimated $2.50 per passenger [for fuel].
$2.50 dollar per passenger !!!!
When Airline charges $400-500 for ticket or more
