A consequence of a weakening airline sector is the pain it will cause plane-maker Boeing (NYSE: BA). With capacity tightening, the need for aircrafts is diminishing.

Imagine planes just sitting idle in the desert. That vision is becoming a reality.

Fortunately for investors, that vision will take time to play out. In the meantime, Boeing gets a free pass as they work through years of order backlog that built up during the last business cycle.

If you take a look at Boeing during the last few months, it is clear that investors have yet to catch on to a world of lower revenues going forward.

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.

As an investor, I really despise the airline sector at the moment. These companies are notorious for being poorly run cash-losing machines.

Now, in the midst of a deep recession and too many airplanes flying too few customers, airline stocks can be expected to be poor performers in the short run and maybe longer.

I made the sector part of my Top 10 Stocks to Avoid in 2009. The main thesis, aside from the obvious recessionary issues, was that oil prices would resume their climb at some point in 2009.

Specifically, I suggested investors avoid Delta Airlines (NYSE: DAL) and United Airlines (NASDAQ: UAUA).

Higher oil prices directly impact the bottom line of the air carriers. The higher oil goes, the more difficult it is for the airlines to make a profit. This summer, with oil prices hitting $150 per barrel, the future of the group was in peril.

That said, the reality of higher prices caused the group to make some necessary changes that included mergers, reduced capacity and important surcharges. The operating environment had the potential to bring much needed discipline to the carriers.

Unfortunately, higher fuel prices did not last long enough to bring enduring change to the group. As prices fell, airline stocks rallied. It was looking good until the economy tanked.

With the recession, oil prices suddenly mattered less. Instead, the focus was on the consumer and business traveler cutting expenses during a contraction.

The airline sector loses if the economy rallies, as such a state brings higher oil prices and lower profit. If the economy stalls, the sector loses customers and revenues fall to unsustainable levels.

The point is that it is no-win situation for the group.

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).

Wall Street's optimism in last week's preview about the earnings of tech stocks wasn't misplaced, as there were many more positive surprises than negative ones among the stocks we looked at. This week will bring plenty more data for investors in and watchers of the sector to mull over. Apple Inc. (NASDAQ: AAPL), AT&T Inc. (NYSE: T), and Microsoft Corp. (NASDAQ: MSFT), for example, are expected by analysts surveyed by Thomson Financial to post modest earnings gains from a year ago, to $1.11 per share (on $8.1 billion in sales), $0.72 per share (on $31.3 billion in sales), and $0.47 per share (on $14.8 billion in sales) respectively. All three of these companies ended the week closer to their 52-week lows than highs, and analysts on average consider them each a buy.

Here's a look at some of the week's biggest expected earnings gainers and decliners in the sector:

• Baidu.com Inc. (NASDAQ: BIDU): $1.25 per share (+44.0%) on revenues of $134.7 million (+103.2%)
• Broadcom Corp. (NASDAQ: BRCM): $0.44 per share (+38.6%) on revenues of $1.3 billion (+33.8%)
• QLogic Corp. (NASDAQ: QLGC): $0.31 per share (+29.0%) on revenues of $170.0 million (+21.2%)
• FLIR Systems Inc. (NASDAQ: FLIR): $0.32 per share (+28.1%) on revenues of $275.2 million (+44.0%)
• Juniper Networks Inc. (NASDAQ: JNPR): $0.30 per share (+26.7%) on revenues of $927.4 million (+26.2%)
• Waters Corp. (NYSE: WAT): $0.75 per share (+17.3%) on revenues of $391.6 million (+11.1%)
• Flextronics International Ltd. (NASDAQ: FLEX): $0.29 per share (+17.2%) on revenues of $8.7 billion (+57.3%)
• EMC Corp. (NYSE: EMC): $0.19 per share (+10.5%) on revenues of $3.7 billion (+12.9%)

Few actors understand the pluses and minuses of hedging better than traders . . . and airlines. In an ironic twist, some airlines could be financially hurt by falling oil prices. That's right: hurt by falling oil prices.

United Airlines (NYSE: UAUA) is one such airline. United said it could lose up to $294 million in Q3 if oil prices average $95 per barrel, marketwatch.com reported Wednesday. Oil rose $2.44 to $109.05 in mid-day Wednesday trading. United purchased fuel caps averaging around $111 per barrel this year and $118 for 2009. In other words, the caps mean United would be compelled to pay more for oil than the market price, due to the established contracts.

American Airlines (NYSE: AMR), and the slated-to-merge Northwest Airlines (NYSE: NWA) / Delta Air Lines (NYSE: DAL) are other carriers that could be hurt by oil hedges, marketwatch.com reported.

Hedges, caps: An attempt to create fixed expenses

Stock Analyst C. Leonard Bauer told BloggingStocks Wednesday most airlines "merely seek to break even with their fuel hedges and caps, not profit from them."

UAL Corp. NASDAQ: UAUA) shares were halted Monday following rumors the company was filing for bankruptcy.

MarketWatch is reporting that UAL said the rumor is completely untrue.

Apparently, an old news item on United Airlines filing for bankruptcy somehow resurfaced on the Chicago Tribune newspaper Web site, CNBC reported. The sell-off nearly wiped out the company's share price, as UAUA, which opened trading at $12.17 this morning, plummeted (according to original reports) 99.92% to 1 cent before being halted. Since then most reports say the stock plunged 76% to $3 (see update for clarification).
[Update 12:35 pm: United issued a statement, saying that the bankruptcy reports are "completely untrue," and that it was actually the "irresponsible posting of a 6-year-old Chicago Tribune article by the Florida Sun Sentinel newspaper website with the date changed" (not on the Tribune site as CNBC reported).
While several sources, including Bloomberg, have UAUA stock plunging to 1 cent on the rumor, most now, including the Nasdaq site, have $3 as the low.]

This isn't the first time rumors in the age of the Internet have caused stocks to plunge, even whole markets. Just recently, Bloomberg had its own snafu when it inadvertently published its updated obituary for Steve Jobs, Apple Inc.'s (NASDAQ: AAPL) CEO. While that didn't cause any reaction as it was caught in time, last year, markets crashed because a website reported of an imminent U.S. strike of Iranian nuclear installations.

Even with some modest recovery in airline stocks, it may be too early to celebrate. The worst may not be over for the industry.

The International Air Transport Association says that global losses for airlines could top $6.1 billion this year. The Wall Street Journal quotes ATA Chief Executive and Managing Director Giovanni Bisignani as saying, "We are bracing for more situations of airlines collapsing" amid higher fuel prices and lower revenue.

The slowdown is apparently moving to Asia, a major destination for many large US and EU airlines.

United (NASDAQ: UAUA) is a good example of a US airline that many thought would be on the rebound. New fear of rising oil prices has spoiled that a bit. After falling from a 52-week high of $51.60, shares crashed to $2.80. They have recently made a minor recovery to $12.40. But, in the last two days, UAUA shares have been off sharply.

Oil is still just below $120. Even at that level, down from $143, airlines face huge increases in fuel prices over last year. A modest disruption in oil supply could send prices back up again.

The market sees US airline stocks as having potential for big returns. But, with the price of oil making a potential bottom, the carriers are still in too much trouble to have a real recovery. Buying shares in the companies still offers more risk than reward. The industry may still have operators that have valuations heading toward zero.

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.

Shares of UAL Corp. (NYSE: UAUA), the parent company of United Airlines, soared today after the Chicago-based company announced it had enhanced its liquidity by $1.2 billion. The company also posted second quarter results that were not as dismal as Wall Street had expected

The company will receive a payment of $600 million from JPMorgan Chase & Co. (NYSE: JPM) related to the advance purchase of frequent flier miles. In addition, the level of reserves that United is required to maintain under its credit card processing agreement with Chase Paymentech has been reduced to $25 million, a move which will free up about $350 million in previously restricted cash. UAL expects the frequent flier payment to improve cash flow by about $200 million over the next two years.

"Combined with the previously announced approximately $550 million raised from new transactions in the second and third quarters, the company will have increased its total cash balance by $1.7 billion and continues to have more than $3 billion in unencumbered hard assets," UAL said in a press release.

United Airlines, the second largest U.S. carrier, increased almost all domestic airfares by 3-5%, due to surging fuel costs, The Associated Press reported Friday.

It was the third increase in the past two weeks, The AP reported, for United (NYSE: UAUA), which like the U.S.'s other major carriers, is struggling to maintain a viable business model amid the largest increase in aviation fuel costs since the world's second oil shock in 1979-80.

Shares of United fell 82 cents to $14.58 on the news in Friday afternoon trading.

United's latest fare hike takes place just two days after Delta Air Lines (NYSE: DAL) CEO Richard Anderson said domestic carriers will need to raise tickets 15-20% just to break even at existing fuel prices, The AP reported.

Surging fuel costs

Independent stock analyst C. Leonard Bauer, formerly of Prudential, said cost factors affecting aviation will create a stark travel choice for business and leisure travelers, at least for the immediate future, including this summer: if you're flying a few months from now, there's an 80-90% chance you'll pay considerably more, he said.

"

In reaction to current record high oil prices, United Air Lines, Inc. (NASDAQ: UAUA) has announced that their passengers are going to have start paying a little extra to cover the airlines rising fuel costs.

Domestic travelers are going to see a fuel surcharge increase of between $10 and $20 for round trip tickets. Prior to this increase, passengers were already paying up to a $35 surcharge on their tickets. Depending on what market you would be traveling in, the increase will vary. For example, in markets where United is in head to head battle with low cost airlines, there was previously no surcharge at all, and those markets will now see a $5 charge each way.

This is the second time this month that United passengers were hit with fee increases. Earlier this month the carrier announced that it would be lifting its rates on its round trip tickets between $4 and $30 in response to the current high fuel costs.
