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.

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

• AirTran Holdings Inc. (NYSE: AAI) reported its third consecutive quarterly profit and will increase capacity.
• Amazon.com Inc. (NASDAQ: AMZN) shares soared after it reported very strong Q3 numbers.
• Apple Inc. (NASDAQ: AAPL) reported stellar Q4 results, driven by the popularity of Macs and iPhones.
• BlackRock Inc. (NYSE: BLK) Q3 earnings soared, due in part to a tax benefit, and assets managed grew.
• Broadcom Corp. (NASDAQ: BRCM) revenue surged sequentially but note the would be flat going forward.
• Caterpillar Inc. (NYSE: CAT) beat Q3 earnings expectations and shares rose though revenue slumped.

Today was one of those days where commodities and the dollar went all over. Gold still rose, yet oil fell on a very mixed inventory report. The markets started out with some strength, but the major indexes were mixed at the end of the day.

Here are today's unofficial closing bell levels:

Dow 9,725.80 -5.45 (-0.06%)
S&P 500 1,057.56 +2.84 (0.27%)
Nasdaq 2,110.33 +6.76 (0.32%)

Midwest Air Group (NYSE: MEH) agreed last week to be acquired by TPG Capital, and CEO Tim Hoeksema relieved investors concerned about its independence by proclaiming, "The cookies stay." The move closed the door on AirTran's (NYSE: AAI) two-year hostile takeover attempt, but reports have now emerged that could allow Northwest (NYSE: NWA), the "passive investor" in the acquisition, to actually own Midwest outright one day.

TPG partner Richard Schifter is quoted by The Associated Press saying "The equity firm may want to cash out of the deal some day, and Minneapolis-based Northwest could become the sole owner." Schifter told the Kansas City Business Journal that a potential acquisition of Midwest by Northwest would be "several years out and isn't anything we expect in the near future."

The potential for Northwest to acquire Midwest one day has definitely ruffled some feathers in the region. The Milwaukee Journal Sentinel said in an editorial that TPG's recent conference call with reporters was "not encouraging" and that questions remain, including if Midwest could survive in the business. The Journal also questioned how "passive" Northwest's relationship with Midwest will be in the future, especially with its "spotty service record."

TPG Capital has a history of working with airlines. Since the main purpose for private-equity companies is to make a profit on their investments, it is only logical to think that Northwest could one day own Midwest outright. It's also possible that TPG could sell the company to AirTran years down the tarmac. Either way, the cookies are safe, for now.

Those were the words from Midwest Airlines (AMEX: MEH) CEO Tim Hoeksema after he announced late last night that Midwest has made a decision, according to the Milwaukee Journal Sentinel. After four hostile attempts from AirTran Holdings (NYSE: AAI) and nearly two years of rejection, Midwest Airlines has finally agreed to be acquired -- by TPG Capital for $450 million.

Hoeksema is expected to remain at the CEO of Midwest. Under AirTran's ownership, he would have been forced to resign.

Midwest Airlines will get to keep its name, identity and independent status with the sale to TPG Capital, as well as the cookies.

USA Today's Ben Mutzabaugh had an interesting Q&A session with Richard Branson, founder of the Virgin Group and Virgin Atlantic Airways, on last week's inaugural flight from New York JFK Airport to San Francisco. Reading Branson's description of the new Virgin flights made me want to book a flight to San Fran immediately.

What interested me from the start of the interview was one of things that Branson said would set Virgin America apart from the other U.S. carriers, something he planned to introduce called "premium economy class." He described this as seating that would be "for people who want more legroom but can't afford first class." Mind you that the most expensive first-class tickets Virgin America has right now are approximately $650, but who wants to pay that for a flight when you can have "premium economy class?"

A quick check on Virgin Atlantic's website, because Virgin America has yet to initiate this service, and they show me that premium economy seating has 38 inches of leg room, compared to the standard 33 inches in economy seating, and a seat width of 21 inches. This is has to be a dream! Once this "premium economy class" comes to Virgin America, I'm certainly going to think of using them for my next flight. More space for less money, it's an amazing concept. I just hope they can last that long in the States with Northwest Airlines (NYSE: NWA), AirTran (NYSE: AAI), Southwest Airlines (NYSE: LUV), US Airways (NYSE: LCC), JetBlue Airways (NASDAQ: JBLU), United Airlines (NASDAQ: UAUA) and all the other U.S. carriers competing for the same ticket.

AirTran Holdings (NYSE: AAI) made another bid for Midwest Air Group (NYSE: MEH) today, pushing to total up to $445 million. The new cash-and-stock offer of $16.25 bid surpasses the $16-a-share cash offer made TPG Capital and Northwest Airlines (NYSE: NWA) on Sunday and is 50 cents higher than their previous last-ditch effort on Sunday, hours before the Midwest Board said it would pursue a rival bid.

This is the fourth time AirTran has raised its bid for Midwest since December. Despite AirTran receiving support from nearly 63% of Midwest shareholders, management refused to relinquish control to the Orlando-based discount airline. Midwest's Board said it would "take AirTran's revised offer under consideration."

While the Board deliberates, let's take a look at exactly what would happen to Midwest if they were to be acquired by either AirTran or TPG/Northwest:

• AirTran wants to rebrand the airline under its own name and integrate Midwest's operations into its broader network.

• Under the TPG offer, Midwest would maintain its brand name and its current management. Northwest, a company that has had nothing but problem after problem since it emerged from bankruptcy earlier this year, would not participate in the management or have any direct control over Midwest. Instead, Northwest hopes to explore cost reduction strategies like joint fuel purchasing.

AirTran President Bob Fornaro said the Midwest Board is required to not only consider the price of a takeover offer but also the effect on employees and the community, according to USA Today. But what about the shareholders? A total of 63% of Midwest shareholders were willing to side with AirTran after a $15.75 offer, and now the offer has been improved to $16.25. It seems pretty clear who the shareholders want to be with.

In another lap tray to the belly, customers of Milwaukee-based Midwest Air Group (NYSE: MEH), repeatedly named as one of the nation's best airlines for customer service and comfort, learned today that the airline will be purchased by a group led by TPG Capital. The investor group includes Midwest's competitor Northwest Airlines (NYSE: NWA), which is reviled by passengers for its cattle-car seating, lack of timeliness and failure to understand the concept of customer service

The acquisition offers little in the way of synergy to the two airlines. They duplicate many routes, and Midwest flies the Boing 717, while Northwest uses 747s and 757s. What the deal does accomplish is to block the expansion of a potential competitor in Northwest's upper midwest routes. While the deal secures the present management of Midwest, I suspect it's just a matter of time before the malaise reaches Milwaukee.

Midwest has been fighting off suitor Airtran Holdings' (NYSE: AAI) hostile takeover attempt, which reached $15.75 and $389 million before it folded its cards late last week. TPG, which grew out of the Continental Airlines (NYSE: CAL) takeover in 1993, is offering $16 per share, or over $400 million, to take the company private. The Midwest board voted Sunday to go forward with the TPG offer, and an agreement is expected by midweek.
