If you think all those new airline fees were a temporary measure to help these beleaguered companies through an economic crisis, you're out of your mind. Now that they've had a taste of how much they can make by charging you for an extra bag or a little more leg room, they're hooked. More important, the fees are making up a meaningful portion of airline revenues and profits, so investors aren't likely to be satisfied with a return to normal – well, they can't. Extra fees are the new "normal."

To get an idea of how poorly United Airlines (NASDAQ: UAUA) has performed, may I suggest viewing this little nugget.

If United is breaking guitars as accused, I would fly another airline. As an avid guitar player myself, such carelessness is unacceptable. The airline industry is struggling, and poor customer service does not help. The above video is now going viral on the Internet - what a PR disaster for United.

Continental Airlines (NYSE: CAL) just got the relief it needs to compete. Despite resistance from the Department of Justice (which can only recommend), the Department of Transportation has granted the airline immunity from antitrust laws. This clears the way for Continental to work with United Airlines (NASDAQ: UAUA) -- and other carriers -- on international routes. Now, the airline can join Star Alliance, which already has antitrust immunity.

At the same time, DOT approved a joint venture among Continental, United, Lufthansa (OTC: DLAKY) and Air Canada. This new relationship would involve trans-Atlantic routes.

Airlines are still having a problem with the economy. Consumers aren't traveling as much, businesses are cutting back on sending executives across country. Indeed, I'm sure the summer months are going to see a lot of vacation plans being eliminated as people decide to stay closer to home.

• Citigroup upgraded Blue Nile (NASDAQ: NILE) shares to Buy from Hold on valuation following the recent sell-off as they believe weakening fundamentals have been factored into estimates and that Blue Nile should benefit from the recent softening of diamond prices.

Singapore Airlines is one of the most successful carriers in the world. Because of the size of its home company, most of its flights are international. Several large U.S. airlines, including AMR (NYSE:AMR) and UAL (NASDAQ:UAUA) rely heavily on their overseas routes for large amounts of their profits. The yield-per-passenger is often better on flights going outside the U.S. than those within American borders.

Singapore Air is grounding a number of its planes as demand for international travel collapses. According to the AP, "The carrier said it will reduce capacity by 11 percent between April and March 2010 from the previous twelve months and decommission 17 aircraft after air cargo shipments fell 20 percent recently." Flying cargo is a separate profit center for a number of large airlines. As sales in that business drop, it compounds losses brought on by falling passenger travel.

Since Singapore Air's cuts are scheduled to go into 2010, the carrier clearly believes that there will not be a short-term rise in air travel.

U.S. carrier stocks have rebounded some from summer lows because of the drop in jet fuel prices. That should help their P&Ls. But if Singapore Air is a canary in the coal mine, the advantage of cheaper fuel may only help the industry so far.
