Readers of this space know that the investment bias is toward large-cap companies with demonstrated business models and who have a competitive advantage in established markets, preferably with a favorable global trend as a support. And with the above in mind, Boeing is worth an evaluation.

The Boeing Company (NYSE: BA) is the world's largest aerospace company.

In general, analysts expect 3-5% revenue growth in FY 2008, and 7-10% in FY 2009 as Boeing's increased aircraft production to meet high order backlogs offsets production delays in the 787 Dreamliner.

Moreover, although not to give short-shrift to Boeing's Integrated Defense Systems division, now the world's second-largest military contractor, behind Lockheed Martin (NYSE: LMT), the major driver of BA's future value-added will continue to be its commercial aviation operation, led by the next-generation 787 Dreamliner.

Higher oil prices and the surging aviation fuel costs they imply may reduce the benefits of an airliner merger, such as the potential deal between United Airlines and U.S. Airways, but they don't eliminate a merger's long-term positives, an analyst argued Tuesday.

Further, C. Leonard Bauer, independent stock analyst, told BloggingStocks Tuesday the potential United-US Airways union would benefit the sector in that it would be the second merger this year among major airlines in the United States, also known as the legacy carriers.

Shares of UAL Corp. (NYSE: UAUA), parent of United Airlines, are down 88 cents to $14.10, while US Airways (NYSE: LCC) are down 55 cents to $7.79 in Tuesday trading.

Sector right-sizing

"The deal would take another legacy carrier off the table, after the Delta-Northwest merger, and that can only help the sector from an earnings standpoint," Bauer said. "The United States airline sector leads the league in airline route redundancy and duplicate hubs. This second deal would further tighten the sector."

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 this case, the official, 'worst-case' scenario may not represent the actual worst-case scenario.

The U.S. Department of Energy, through its Energy Information Administration unit, has already released its projection for U.S. summer gasoline prices, and it expects the average U.S. price to peak at $3.60 per gallon by late spring/early summer. The current average is about $3.35-$3.38 per gallon.

Meanwhile, oil Friday flirted with yet another all-time high. Oil rose 73 cents to $115.59 per barrel, while wholesale unleaded gasoline gained 1 cent to $2.95 per gallon. On Thursday billionaire investor and oil industry guru T. Boone Pickens told Bloomberg News oil is headed for $125 per barrel.

The EIA does not expect much of a price rise beyond the $3.60 level because it expects U.S. consumers to cutback consumption to contain their transportation fuel bills amid the record-high prices. And, in fact, there's considerable evidence to support the EIA's demand projection: for the first time in more than a decade, weekly U.S. gasoline sales have declined on a year-over-year basis for more than two months.

Gasoline prices have continued their charge up to $4 a gallon today, rising to a new record high of $3.418 after jumping 1.9 cents last night.

Gas prices have been rising sharply over the past few months in reaction to record high oil prices and a weak dollar, and some analysts are already predicting that we will be seeing $4 a gallon before it is all said and done. Diesel prices also rose to a new high, hitting $4.146 per gallon.

As we noted in earlier discussions, gas prices are only expected to move higher in the next few months as more drivers hit the road for their summer vacations. The heavy demand summer driving months always apply upward pressure to prices, and despite the current high prices, summer demand will definitely push prices even higher.

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.

With Delta Air Lines and Northwest Airlines said-to-be-close to announcing a merger, according to Reuters, analysts and business executives will closely-evaluate the proposed deal's details, parsing it to see if it is capable of creating something the land of the free hasn't experienced in quite some time: a profitable major airline.

Turning aside (for the moment) points that argue that with the added cost of public subsidies of aviation and aerospace research, it's hard to envision a U.S. airline as ever being truly 'profitable,' independent stock analyst C. Leonard Bauer told BloggingStocks Monday the merged Delta / Northwest could create an assertive airline capable of racking-up revenue, even as it spurs aviation innovation and change.

The cost of gasoline has once again risen to new record highs this weekend, as the cost for a gallon of gasoline jumped another 0.8 cents to a national average of $3.365 a gallon.

At current levels, consumers are spending 54 cents a gallon more for their gasoline they were this time last year, marking a 19% one year jump in gasoline prices. And for those of you that are hoping to get some relief from the current prices ... don't hold your breath. According to AAA, you should only be expecting to see prices continue to move higher.

One of the main reasons why prices should continue to move to the upside is that we are just now about to enter into the high demand summer driving months. Industry experts have already estimated that prices will continue to move higher, inching their way up to $3.60 a gallon, but there are plenty of analysts out there who are under the impression that we could see prices move even higher, possibly up toward $4 a gallon.

As you know, American Airlines -- AMR Corp (NYSE: AMR) has been having a tough week. The company started running a new round of inspections on Tuesday which has led to large cancellations for the past 4fourdays.

Today, once again there were more cancellations, with another 595 flights being grounded. It can be very frustrating to find out your flight has been canceled, but some airports are upping their efforts to accommodate the unlucky passengers. All combined, the airliner has been forced to cancel in excess of 3,000 flights this week, impacting some quarter of a million travelers.

We have all had to deal with canceled, or delayed flights... and one thing is for sure, it is never a pleasant feeling, so you can just imagine the mood in airports all across America in reaction to this week's mess. Well, according to a story from MSNBC, some airports are taking extra steps to help make American passengers as comfortable as possible.

It's another day of cancellations for American Airlines -- AMR Corp (NYSE: AMR) -- as its current round of plane inspections is moving slower than had been anticipated.

Roughly 900 of the airlines flights have been canceled today, representing around 40% of its usual daily flight volume. The delays started on Tuesday when the American announced that it had to re-run inspections that it held last month after the FAA decided that the work done did not meet its standards.

On Tuesday the airline canceled 460 flights, and then another 1,094 yesterday, so it has been a tough few days for passengers trying to get to their destinations. All in all, over 100,000 passengers have been effected by the current situation at American.

The stalled Delta Air Lines (NYSE: DAL) / Northwest Airlines (NYSE: NWA) deal talks should regain momentum next week, provided Delta's management makes progress in talks with its pilots, The Wall Street Journal reported Wednesday (Subscription required).

Further, independent stock analyst C. Leonard Bauer, said that while the Delta / Northwest talks have been stalled at a traditional, formidable hurdle -- pilot seniority and pilot flight schedules -- "the stars now appear to be lining up to get this deal done."

Bauer said that since the talks began, recent data released indicates that the U.S. economy has continued to slow, and is most likely already in a recession -- never a good backdrop for airlines -- which depend on consumer disposable income for a portion of their revenue. Further, oil has resumed its 'regularly scheduled' movement: up, which has increased aviation costs by at least another 10-15%. Or as Bauer put it, "From a fuel cost standpoint, this is no time to fly commercial jets around less than half full." Oil rose $3.71 to $112.21 per barrel -- an all-time high -- Wednesday afternoon after an unexpected decline in U.S. weekly oil inventories.

American Airlines -- AMR Corp (NYSE: AMR) -- is once again canceling massive amounts of flights in order to inspect the bundling of wires in some of its airplanes. You may recall, that this is the same situation that led to around 400 cancellations last month, and this current inspection is estimated to affect even more flights, with up to 500 flights being canceled.

The current round of cancellations, which represents about 20% of total American flights, started late Tuesday afternoon, and was expected to last Tuesday night and into Wednesday, and possibly even beyond.

Passengers that were scheduled to fly the canceled American flights have been switched over to alternative American flights, or placed on other airlines that service the selected routes.

Don't look for airlines to stop raising prices anytime soon, nor bend over backwards to provide creature comforts to travelers, according to one analyst.

Further, Northwest Airline's (NYSE:NWA)most recent decision to increase "fuel surcharges" - - i.e. raise ticket prices - - will remain a sector theme for at least the next few quarters, so says independent stock analyst C. Leonard Bauer.

"Airlines are facing rising fuel costs at a time when passenger demand is still solid. That means they have power to raise prices and pass their higher costs on to the consumer," Bauer told BloggingStocks Friday.

Fuel surcharge

Northwest announced Friday that on March 18 it raised fuel surcharges generally by $10 or $20 each way for flights from North America to Europe, India, Japan and most other destinations in Asia, The Associated Press reported Friday. That brings the surcharges to between $115 and $155. The surcharge on flights from Japan to North America will rise by $20 to $160 beginning May 1. Northwest also said it plans to freeze hiring pilots and flight attendants and cut domestic schedules by 5% beginning in September 2008, The AP reported.

Northwest's shares fell 5 cents to $9.16 on the news on Friday at mid-day.

I have had some clients ask me, what industry I think will benefit from the $600 rebate checks that are due to be sent out as part of the U.S. economic stimulus package. I think airlines will benefit, especially lower cost carriers like Southwest (NYSE: LUV) and Jet Blue (NASDAQ: JBLU).

The USA Today has an article about the kind of vacation you can have for $600. The article says: "With most Americans expecting to receive a tax rebate of up to $600 ($1,200 for married couples), there are plenty of ways to get the most vacation for your buck, say travel experts. Whether it's a cruise, a tropical paradise, or family travel, these trips can all be done for under $600 a person."

Because we aren't talking about flying around the world or across the Atlantic for that measure, trips to Las Vegas or Orlando, for example, will fit the family, and of course people need a way to get to these destinations, so that's how the airlines become interesting. Throw into the mix potentially stable or even lower fuel costs, and for investors looking for a way to play the "Rebate check" game, you may want to take a look at the airlines.

For anyone who has plans to fly on American Airlines, AMR Corp (NYSE: AMR) or Delta (NYSE: DAL) today, you may want to call ahead and verify that your flights are still taking off as planned, as both airlines are canceling hundreds of scheduled flights today.

Both carriers are grounding a large number of flights as they continue to hold inspections on wiring bundles on some of their planes. For American, the company is planning to ground 132 of its flights today, while Delta is canceling 275 flights.

The Federal Aviation Administration is in the middle of a massive inspection project, in which it stated that it will be inspecting 10 safety orders (also known as airworthiness directives) at every single major airline by March 28. This comes after a scandal broke out over missed inspections at Southwest Airlines (NYSE: LUV) earlier this year.
