"The cost of operating a commercial aircraft can be broken down into two main categories: airborne cost and ground cost. The airborne costs are the actual costs of flying the aircraft; the ground costs are the cost of the airframe, engine maintenance, as well as airport and hangar expenses. Both are typically measured hourly and are broken down per mile. The cost per seat mile is the cost of flying one passenger one mile and is used to measure operating costs. The average cost per seat mile is around 7 to 8 cents for low cost carriers and 11 to 12 cents for network carriers.
Labor and fuel are the largest expenses, accounting for about 12% of the total cost. On average, a pilot’s salary begins at $36,000 and caps around $196,000. The average fuel consumption per 100 kilometers is 3.035 liters (78.5 mpg) for turbo props, 3.126 liters (76.3 mpg) for regional jets, 2.405 liters (100.5 mpg) for short haul, 2.74 liters (86.8 mpg) for medium haul, and 2.959 (80.84 mpg) liters for long haul."

That means that since the air travel shortest distance between New York and Los Angeles is 2,451 miles, it costs the airlines $294.12 (at 12¢/mi) to fly a passenger that distance (and that is assuming that the aircraft is full). The cheapest seat that I could find was a JetBlue super economy one at $83.00 but the stipulations surrounding getting that fare make it more of a bait and switch than an actual price. The major airlines (including JetBlue) appear to have a common price of $249.00 as their "realistic" lowest fare.
If the aircraft is a 500 seater and is flying with only 100 passengers, then the cost per OCCUPIED passenger seat becomes 60¢/mi and that would mean that the "break even" fare would be $1,470.60. Now, a fare of $1,470.60 is obviously impractical, that means that the government is going to have to provide a subsidy of around $88,236 per flight just to ensure that Americans can fly from New York to Disneyland.
