This move will be funded mainly with debt, and it will help Southwest establish a larger presence in cities like Boston and New York. What's more (as the article points out), Southwest will now be in "head-to-head competition with Delta Air Lines in Delta's home base of Atlanta."

For years, it's been evident that smaller airlines have had an operating advantage, particularly when they use less expensive airports. They've been able to post better numbers as a result, and in the current travel slump, they've outperformed the larger carriers. Well, they've also picked up a considerable amount of market share.

According to a report by USA Today, low cost carriers now have 30% of the market in the United States. Price-sensitive consumers are turning to cheaper alternatives, even if it means (for fliers with elite status) giving up the perks they've earned through years of customer loyalty.

United Airlines (NASDAQ: UAUA), US Airways (NYSE: LCC) and American Airlines (NYSE: AMR), according to an influential analyst, have run out of options. Jamie Baker of JPMorgan said in a July 20, 2009 report that these companies couldn't do anything to prevent a cash crisis. They only savior available to them would have to be an outside investor. To call the position grim would be optimistic. Unfortunately, it couldn't have come at a worse time.

As Baker was walking the bear into the airline industry, United was starting to celebrate its change in direction. The carrier has improved its on-time rate, according to a USA Today report, and its operations are coming around. Despite the fact that the airline industry has been brutalized by the global recession, the airline has made some progress. Through August, the company's share price doubled, and its ascent has continued in September. So, the company is locked in an ongoing struggle to manage its identity, cope with its past and shape how the world sees it today.

The operational "makeover" has resulted in a reduction of its fleet from 601 jets in 2000 to 386 as of the summer of 2009. In terms of passenger traffic, it's in the #4 spot in the United States – trailing Delta (NYSE: DAL), Southwest (NYSE: LUV) and American. With Q2 revenues off 25.2% year-over-year, however, drastic measures are still necessary.

Shares of Southwest Airlines Co. (NYSE: LUV) were down as much 1.5% in New York trading following published reports that the company grounded 46 planes Saturday due to maintenance concerns. The Dallas-based carrier saw its shares fall to as low as $8.55 just past noon after news broke that the Federal Aviation Administration is investigating the airline's use of unauthorized parts and repairs on its aging fleet of 737-300 and 737-500 jets, manufactured by Boeing Co. (NYSE: BA).

An FAA inspector working Friday at a maintenance shop used by Southwest questioned whether some hinge fittings -- used to divert hot engine exhaust from aircraft wings -- installed on the 737 jets were authorized for use. After hasty consultations with the FAA and Chicago-based Boeing, Southwest decided to ground the planes.

There may be new hope for the perpetually ailing airline industry. While I wouldn't expect these companies to become top performers anytime soon, it looks like the best revenue stream is the one nobody's been talking about: change and cancellation fees.

These penalties, which can reach up to $150, bring $2 billion in revenue into the industry annually. According to the Department of Transportation, they were good for $527.6 million in the first quarter -- in the United States alone. This is 3.2% of U.S. airline revenue.

American Airlines parent AMR (NYSE: AMR) raked in $116 million in revenue from these penalties in the first quarter of 2009 -- compared to $108 million from the more highly publicized extra bag fees. For JetBlue (NASDAQ: JBLU), the numbers are smaller (JetBlue, of course, isn't as big as AMR) but no less compelling. By pumping its change and cancellation fee from $100 to $150, the airline scored $32.2 million in Q1 2009, up from $25 million in Q1 2008.

Alcoa Inc. (NYSE: AA) started off the new earnings season with disappointing results that helped to stifle the recent rally. Was that enough of a sign of what's to come? No, probably not. But the earnings reports start to fly in earnest this week, which should provide a more detailed picture of the state of things.

Analysts surveyed by Thomson Reuters anticipate that some of the biggest names will prove to be holding their own. Google Inc. (NASDAQ: GOOG) is expected to post a profit of $4.91 per share, marginally higher than a year ago, and Johnson & Johnson's (NYSE: JNJ) expected $1.22 per share profit is slightly lower year over year. Even Mattel Inc.'s (NYSE: MAT) estimated loss of $0.13 per share is the same as in the year-ago period.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Advanced Micro Devices Inc. (NYSE: AMD) reported dismal Q4 results due to lower demand.
• AMR Corp. (NYSE: AMR) reported a bigger-than-expected Q4 loss, sending shares lower.
• Check Point Software Technologies Ltd. (NASDAQ: CHKP) earnings prospects led to an upgrade.
• eBay Inc. (NASDAQ: EBAY) posted Q4 and full-year results with increased revenue due to a stronger dollar.
• Google Inc. (NASDAQ: GOOG) reported strong Q4 numbers that beat analysts' expectations.
• International Business Machines Corp. (NYSE: IBM) reported better-than-expected Q4 and 2008 earnings.
• Lockheed Martin Corp. (NYSE: LMT) posted strong Q4 results but lowered its 2009 guidance.
• Northern Trust Corp. (NASDAQ: NTRS) shares surged after posting better-than-expected earnings.
• Regions Financial Corp. (NYSE: RF) reported a huge loss due to write-downs and offered a bleak outlook.
• Societe Generale said that it expects to have broken even in the final quarter of 2008.
• Southwest Airlines Co. (NYSE: LUV) posted its second straight quarterly loss due to fuel hedging costs.
• UAL Corp. (NASDAQ: UAUA) reported a huge loss on the erosion in value of oil hedges as prices dropped.
• Usana Health Sciences Inc. (NASDAQ: USNA) posted record Q4 results despite one-time charges.

Southwest Airlines (NYSE: LUV) is famous for making a profit every year since it got started in the 1970s. Given the billions that the airline industry has lost in the last several years, that's quite a feat. And I've posted about how Southwest has been able to sustain that superior performance. But now Southwest's streak could be in danger.

How so? Southwest lost $56 million in its fourth quarter -- its second in a row, because it bet that the price of jet fuel would continue to climb. Southwest had to post cash collateral after jet fuel fell 65% in 2008's second half to less than the rates in its contracts. Southwest reduced most of these fuel hedges in December. Southwest also cut its plans to expand in 2009 -- it will pull 15 aircraft from flying this year as it adds 13 new planes, and it will delay some 2010 deliveries.

But here's the good news -- Southwest made a profit of 8 cents a share excluding $117 million in costs related to fuel hedging -- 3 cents a share above the 5 cents analysts had expected it to earn. But the question that remains for Southwest shareholders is whether it will make a profit in 2009. The answer depends on whether it can cut back on capacity to match lower demand in an economic downturn and whether its fuel hedges will make or lose money for Southwest.

That market may be betting that it can keep its streak going. Its stock is up 6.4% in pre-market.

I think it's fair to say that there's much trepidation about the earnings season that picks up steam this week. And for better or worse, numbers from the big financials have begun to roll in. Last week we saw profit sink for JPMorgan Chase (NYSE: JPM) and significant losses from Bank of American Corp. (NYSE: BAC), Citigroup Inc. (NYSE: C), and Deutsche Bank (NYSE: DB).

Analysts surveyed by Thomson Reuters expect Bank of New York Mellon Corp. (NYSE: BK) to be among those financials reporting fourth-quarter earnings growth this week. They anticipate that Bank of New York will post a profit of $0.70 per share, compared to $0.67 per share a year ago and $0.72 in the previous quarter. Revenue is expected come to $3.8 billion, about the same as it was a year ago. Bank of New York has fallen short of earnings estimates in two of the past five quarters, by as much as 11.1%. For the full year, analysts are looking for $2.78 per share (+5.8%) on $14.8 billion (+4.2%). The consensus recommendation of analysts is to buy BK, and the long-term EPS growth rate forecast is 10.7%. Shares are 48.7% lower than a year ago. Other financials expected to report quarterly earnings growth this week include SunTrust Banks Inc. (NYSE: STI) and M&T Bank Corp. (NYSE: MTB).

What's holding the airline sector back, in addition to high jet fuel prices, and keeping the likes of AMR's (NYSE: AMR) American, Delta (NYSE: DAL), UAL's (NYSE: UAUA) United, Southwest (NYSE: LUV), and Continental Airlines (NYSE: CAL) from realizing their potential?

Many economists and analysts would agree that, along with other infrastructure and related investments, the nation's air traffic control system must be upgraded, if the United States seeks an air transportation system capable of maintaining a high level of safety -- and better service -- in the 21st century's more-crowded skies.

Further, that the United States has not already replaced an essentially generation-old air traffic control technology with a modern system is a serious demerit, and one that has -- through delays, cancellations, and other problems -- taken a toll on the flying public and the major carriers.

We have all been there before, standing beside the luggage conveyor belt after a long flight, quietly praying for our luggage to magically pop out of that little window and slide our way. When our luggage finally shows up, it typically means the end of a long day that generally has the potential to stress out most travelers.

For me at least, as long as I get my luggage I am satisfied with my trip. But for a lot of us, there are several factors we use to grade the airlines, and a recent survey shows that customer dissatisfaction is running at near record level lows. These factors include anything from planes leaving and arriving on time, to the service inside the plane from fight attendants, to just how easily mishaps get handled by the agents at the ticketing desks.

Having lived in Europe the past few years, I have been no stranger to the long distance flight back and forth to the States. I suppose I have traveled roughly 100,000 miles on airlines over the past couple of years, and I have to say that for the most part I have had very pleasant experiences. My girlfriend was unfortunate enough to have lost some luggage for a week over this past Christmas, but other than that, I have been pretty lucky.

Analysts surveyed by Thomson Financial expect Southwest Airlines Co. (NYSE: LUV) and Pfizer Inc. (NYSE: PFE) to post smaller profits in the first quarter. Both companies are scheduled to report results on Wednesday.

Southwest is expected to essentially break even as far as earnings are concerned, which is down from the same period in 2007 when it earned four cents per share. The company has beat quarterly estimates recently. It only just beat the consensus third-quarter 2007 estimate, but beat the fourth-quarter estimate by 21.2%.

Dallas-based Southwest's low-cost, no-frills approach has made it one of the leading U.S. airlines. In the past year, the company's revenues were $9.8 billion and its net income totaled $645 million. Its EPS growth forecast for the year is -28.7%, worse than the industry average but better than that of rival JetBlue Airways (NASDAQ: JBLU). The consensus recommendation of analysts remains to buy Southwest.

The stock has fallen 18.5% in the past year and trades at a P/E of 14.7. Shares closed Tuesday at $12.35.
