Delta Air Lines (DAL - option chain) stock is trading lower today along with other airlines this morning, hurt by rising oil futures. Oil futures shot up over 7% this morning in response to growing political turmoil in Libya. Libya is the largest oil producer in North Africa, and is responsible for 2% of global daily output. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on DAL.

This morning, DAL opened at $10.99. So far today the stock has hit a high of $10.99 and a low of $10.59. As of 12:35, DAL is trading at $10.65, down $0.85 (-7.3%). The chart for DAL looks bullish and S&P gives DAL a positive 4 STARS (out of 5) buy ranking.

U.S. stock futures are mostly higher this morning as investors await earnings reports from several companies. However, shares of Apple Inc (AAPL) dropped in pre-market trading. Futures on the Dow Jones Industrial Average rose 37 points to 11,762.00 and S&P 500 futures gained 2.20 points to 1,292.20. Futures on the Nasdaq 100, however, dropped 12.50 points to 2,307.50.

U.S. markets were closed on Monday for the Martin Luther King Day holiday. Stocks closed higher on Friday, with the Dow gaining 55.48 points, or 0.47%.

The earnings season ramps up this week. Analysts polled by Thomson Reuters foresee strong reports from such big names as Apple (AAPL), eBay (EBAY), IBM (IBM), General Electric (GE), Google (GOOG), Schlumberger (SLB) and Southwest Airlines (LUV). And fast on the heels of last week's big earnings beat from JPMorgan Chase (JPM), there will be plenty more results from the financial sector to peruse this week.

Among the financials expected to post double-digit earnings growth this week are Capital One Financial (COF), Morgan Stanley (MS), SLM Corp. (SLM) and U.S. Bancorp (USB), but the week's biggest earnings winner may be Wells Fargo (WFC).

After a decade of sub-par operations and just plain old bad luck, the U.S. airline sector may be set to soar, and Delta Air Lines (DAL), first discussed here on July 19, 2010 at a price of $10.73, may be the leader of the pack.

Even so, keep in mind that I consider Delta to be a high-risk stock not suitable for moderate-risk or low-risk investors. Don't consider DAL if you can't tolerate a 30-50% drop in the stock's price: it could happen.

Look for Delta's 2011 revenue to jump 11-14% on higher fares and a 1 percentage point rise in its load factor. Enhanced economies of scale stemming from the Northwest Airlines merger, and checked bag and other fees compliment the favorable revenue side of the equation.

More Monday merger fun, this time from the airline sector. Reportedly, Southwest Airlines (LUV) announced that it will purchase AirTran Airlines for roughly $1.42 billion.

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."

Early this morning, United Airlines (UAUA) and Continental Airlines (CAL) announced that they will join forces to create the world's largest airline in a $3 billion deal.

The new airline will be bigger than Delta Air Lines (DAL) and will send flights as far as Shanghai and South America. The companies believe that the span of destinations should attract more business travelers and their higher fares. The deal, which will need approval from shareholders and antitrust regulators, is expected to close in the fourth quarter. The new company will be known as United Continental Holdings and will be based in Chicago. The airline's largest hub will be located in Houston.

The silver lining to the travel slump last year was that fewer flights made it easier for airlines to hit their deadlines. In 2009, the airline sector had its best year for on-time arrivals since 2003, largely because many routes were cut as passenger traffic fell and companies looked for ways to cut costs. According to the Department of Transportation, airlines hit a 79.5% on-time rate last year (which includes flights that were within 15 minutes of their arrival time).

Hawaiian Airlines had the best record, but it's a small regional, lacking the challenges of the major carriers. Among the big guys, Southwest's (LUV) 83% on-time rate was best, and United's (UAUA) 81% was tops for traditional air carriers. Of course, these airlines and the rest of the sector were helped along by the fact that they pad their schedule, which makes it a hell of a lot easier to show up on time.

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.

Across the country, big jets are disappearing -- nudged shoved aside by the little guys, which are cheaper to operate and don't require as many butts to fill seats.

The number of empty seats falls, and revenue per available seat-mile (RASM) goes up. It's pretty straightforward. But, for crowded flights, this could leave a few people stuck without their preferred routes. The alternative, of course, is an unsustainable status quo, in which a few passengers remain happy ... until the airline folds.

Business travelers still aren't coming back to the good seats, despite airlines' best efforts. FareCompare.com reports that many business class tickets to Europe are going to be 33% to 66% cheaper this fall relative to last year. Companies are being careful with their cash – which means stacking people in coach rather than giving them a little leg room on overseas flights. With back-of-the-plane tickets going for a quarter of the price (or less) than their business class equivalents, this isn't exactly shocking.

On Wednesday, Delta's (NYSE: DAL) cheapest NYC-to-London's cheapest roundtrip coach fare was $716 (for an October 23 departure and October 30 return), according to a report in USA Today. To take the same trip in business class, you were looking at a hefty $4,634. So, even though prices are down year-over-year, it doesn't mean that business travelers are being allowed to enjoy the opportunity.

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.

Japan Airlines (OTC: JALSY) gained 8% Monday morning, thanks to weekend rumors that Delta Airlines (NYSE: DAL) and American Airlines (NYSE: AMR) are vying for a piece of the largest airline in Asia's largest travel market. Both Delta and American hope to use an investment in JAL to gain broader access to the Japanese travel market.

Though JAL refuses to comment on any talks, it's been reported over the weekend that Delta could be interested in buying a minority stake in the airline for several hundred million dollars, while American's bid could be $1 billion or more for a joint venture. At the same time, JAL has mentioned wanting to raise a total of $2.8 billion.

Delta Airlines (NYSE: DAL) is looking to buy a piece of Japan Airlines (OTC: JALSY). The move could give the world's largest airline access to more cities in Japan.

A source close to the talks says that the investment would be several hundred million dollars and would open the door for an alliance between the two that would allow each airline to book passengers on the other's flights.

August brought more misery to the airline industry in the United States. Seven of the country's nine largest carriers saw traffic drop, with only Southwest Airlines (NYSE: LUV) and JetBlue Airways Corp (NASDAQ: JBLU) bucking the trend. The continued upward climb of unemployment, tighter corporate budgets and sluggish demand for leisure travel has resulted in fewer passengers in seats.

JetBue was the only carrier not to report a drop in available seat miles (ASMs), the primary measure of airline productivity. Load factors, however, which indicate how full a plane is, tended to be higher, largely a result of flights that have been cut in an effort to reduce costs.
