Well the fact is that the airlines are and will always be subject to regulation.
Absolutely. And I believe that the airlines should be subject to safety and security regulations. That is imperitive. However, the airlines should not be subject to market regulation.
While some small airlines are showing a profit, although JetBlue's margins are sinking, these are not the carriers that move most of the people.
Last time I heard, Southwest was the number 4 airline in terms of passengers boarded, and they dominate something like 75% of the top 100 O&D markets. Southwest alone serves a large portion of the market. You are correct, they do not serve the "majority" of travellers. However, they do show that transporting people via aircraft can be a profitable business, and not just a path to profits for all the other companies you listed (aircraft lessors, hotels, tourist attractions, etc).
If its ok to let the market "work" and you go out and plan your trip only to find out that the carrier folded the night before, and no other carrier will honor the ticket, because after all they did not sell it to you, once again dont complain.
Well, first of all, congress has passed the bill that requires other airlines to accept the tickets of a failing carrier again. This legislation had recently expired, but will be renewed. I am not 100% up on its process through the legal system, but its difficult to imagine "W" using his first veto on this.
In fact, I had this event happen to me. It was a pain. I worried about it. I was accomodated on another carrier and my trip went as planned. Folks buying a ticket on US Airways, United, and ATA are taking a risk. They should know that.
Competition eventually comes to a conclusion, and that conclusion is a monopoly, well when that happens and ticket prices triple, because we let the "market" work, dont complain.
Can you name one industry in which "Competition eventually came to a conclusion" and has lead to a monopoly?
Now of course you will say that if that happens others will start up, but there is one thing that your little market theory ignores, its the fact that a major can simply underbid a smaller rival until that rival runs out of money, the major can make up for its losses on routes not served by the small start up. So when the industry ends up as a monopoly and triples the fares, dont complain, because the market works, right?
Well, lets face it. The strategy you have described has partially led to the problems faced by the legacy carriers today. LCC's are attacking the legacies on multiple fronts... Remember "fortress" hubs like ORD and DEN and ATL and STL and DFW and PHL, which today all have LCC competition. Remember when the legacies were able to bank on their long-haul services, like transcons, to remain profitable. Remember when legacies could count on sky-high fares in small towns like ERI to remain profitable. The LCC's have collectively removed those profitable operations, so now their are no profits to subsidize the loss makers. That is a bad business strategy.
5 years ago, the majors could underbid rivals. However, todays rivals are the best financed start-ups in history. jetBlue had the most investment capital of a start-up since deregulation, and ACA/Independence Air was able to open a hub with 300 flights/day in two months. These airlines are not the under-funded 3 airplane start-ups of 10 years ago. And in fact, we have Sir Richard, "waiting in the wings" so to speak, to start another well-financed lean LCC machine. These are not the rinky-dink start-ups of years past, and thus far, the legacies have not been able to "crush" them despite their best efforts (like Song, Ted, MetroJet, fare wars, rolling hubs, and if you call ERJ's on LGA-BUF a best effort to crush jetBlue).
If demand exists then prices can be raised. People are not going places just because the fares are cheap, they have spend money when they get to where they are going. Besides is it reasonable to be expected to be transported 3000 miles in 5 hours for less than the cost of a tank of gas?
Last time I checked in Econ 101, prices of any product are function of both demand and supply. Demand at "profitable" price-points for the legacy carriers has dried up. Meanwhile, there seems to be an unlimited supply of low-fare seats by the LCC's and Legacies combined. Prices will not increase on demand alone... If demand is increasing and supply is increasing at the same rate, fares will remain the same. And the last time I checked, the LCC's collectively have something like 400 airplanes coming into the USA system in the next few years.... Supply will increase. In fact, supply might increase faster than demand, depressing prices even further... I encourage you to look into Econ 101, because these are really the basic concepts, and they really do apply.
