I recall reading a couple of years ago that as an industry the airlines have NEVER made much money – during the regulation era route monopolies, various subsidies and contracts to carry mail kept them going, but during the dregulated era, they didn’t even have those to prop them up.
One reason is that transportation companies have enormous fixed costs – what they have to pay for the equipment, personnel, airport gate rental, etc. stays roughly the same whether the plane takes off nearly empty or full, or whether it takes off at all, for that matter.
Airlines in particular have to deal with the weather. A thunderstorm or snow storm that closes a hub airport sends shock waves through the entire system, fouls up schedules, forces rebooking of passengers and so on.
Airlines use huge amounts of fuel every day, so even a price change of a penny per pound of jet fuel can mean the difference between decent profit or big loss. They can hedge this somewhat with fixed-price contracts, but if they haven’t anticipated their fuel needs exactly, they have to buy additional fuel on the even-more-expensive spot market.
Most U.S. airlines rely on high-fare business travelers for the bulk of their revenue. Obviously, you’d rather have 10 business travelers paying the full $600 fare and fill the rest of the plane with $99 vacation travelers, than have an entire plane full of vacation travelers. However, for years businesses have been squeezing travel costs as much as possible, which also squeezes the airlines (also business hotel chains and rental car companies.)
Southwest is unique for a number of reasons. For one, they stay away from the more expensive airports (Love Field in Dallas instead of DFW, Providence instead of Boston, etc.) That works fine for recreational travelers, but a business executive going to a meeting wants to fly into New York City, not Long Island.
For another, Southwest only flies a single type of airplane, the Boeing 737. That means lower maintenance, training, etc. Again, that works for them, but United can’t exactly fly a 737 from New York to London, or a 747 from New York to Boston six times a day.
Southwest is also a non-union airline with entirely different work rules that keep its personnel costs lower. Good for them, bad for their employees. You be the judge of whether that’s good or bad for society as a whole.
Could the airline industry use an entirely new business paradigm? Sure. Does that mean that it’s a corporate ploy to con the taxpayer? Not necessarily. Consider the number of legendary airlines that have failed over the years – Eastern, Braniff, Pan Am, TWA and the list goes on – it’s a pretty good indication that profits aren’t automatic.
