But the higher fares are not diminishing the demand... The nation's airline industry continued to enjoy strong financial data with fresh government statistics showing that the average domestic air fare for 2014 was $391, the highest fare since the federal government began tracking the data in 1995. But the higher fares are not diminishing the demand for air travel.
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 pilotâs salary begins at $36,000 and caps around $196,000.irect maintenance on the airframe is around $200, engines are around $140, and maintenance burden is around $140, for a total of $480. Also added to this cost is depreciation of $247 and aircraft rental of $216. An average flight on an American Airlines MD-88 costs $4938.5 per hour.
