From Alaska to Allegiant–Airlines Differ in Efficiency

airline fuel efficiencyAirlines are always obsessing over fuel costs. It’s a crucial aspect of their business, after all, and accounts for 1/3 of their operating expenses. So you might think that all the major airlines do roughly the same things to minimize their fuel use. But that doesn’t seem to be true. The Washington Post (Sept. 21, 2013) reports that there’s actually a surprising amount of variation in how airlines burn fuel. It ranked the 15 biggest U.S. airlines by fuel efficiency and found very large disparities, as seen in the attached graph.

The least efficient airline, Allegiant Air — a low-cost carrier that targets smaller airports — used 26% more fuel than the most efficient, Alaska Airlines, to achieve a similar level of transport.

So why is there such a huge disparity? Here are a few possibilities:

– Differences in technology: About 1/3 of the variation likely comes from the fact that different airlines use different technology — they don’t all deploy the most advanced, efficient aircraft. Allegiant, for instance, has a fleet of McDonnell Douglas aircraft that dates back to the 1970s. Alaska Airlines, by contrast, uses newer Boeing planes that have technologies like “winglets” to reduce fuel burn.

– Differences in operations: Technology can’t explain all the disparity in fuel efficiency. Some airlines, like Southwest, manage to operate older aircraft quite efficiently. Other airlines, like Virgin, have newer aircraft but are relatively inefficient.

– High oil prices don’t necessarily drive fuel savings. The most efficient airlines aren’t necessarily the most profitable. Allegiant was the least-efficient airline in 2010 but also the most profitable. That’s because it tends to serve airports that other airlines neglect, giving it more leverage to raise prices on routes.

When Technology Fails

New Fairbanks Airport barricadeWe are certainly a technology driven society, with our ATMs and EFTs, on-line newspapers and e-books, robotic surgery and robotic butchering, and optical scanners. So what happens when something as simple as a phone app for navigation fails?

If you are headed for the Fairbanks, Alaska, Airport, just don’t ask your iPhone for help. The Detroit News (Sept. 27, 2013) reports that Apple has disabled driving directions to the Fairbanks International Airport after a glitch in its maps app guided drivers to the edge of a runway instead of a terminal.  Two times, drivers continued on and cut across an active runway to reach the terminal. Now, when someone puts in the airport as their final destination, a message pops up and says, “Directions not available, direction cannot be found between these locations.”

Previous directions on newer iPhones and iPads guided drivers to the edge of the tarmac instead of the correct route to the terminal. In incidents Sept. 6 and Sept. 20, drivers went through a gate, past warning lights and signs, and then across an active runway, to reach the terminal. The first mishap involved an out-of-state visitor trying to return a rental car before a flight, and the second was an Alaska resident trying to get to the airport.

The airport has since barricaded that entrance to the taxiway. A sign posted there gives a phone number for people to call to get the correct directions to the airport. After the first incident, airport authorities immediately contacted Apple requesting a fix.

Textile Plants Humming Once Again in the Carolinas

Posted on by

SEPTEMBER 23, 2013

The old textile mills in the Carolinas are mostly gone now. Gaffney Manufacturing, National Textiles, Cherokee — clangorous, dusty, productive engines of the Carolinas fabric trade — fell one by one to the forces of globalization. Just as the Carolinas benefited when manufacturing migrated first from England to New England and then to here, where labor was even cheaper, they suffered in the 1990s when the textile industry mostly left the US. It headed to China, India, Mexico — wherever people would spool, spin and sew for a few dollars or less a day.

But remarkably, Parkdale Mills, the country’s largest buyer of raw cotton, has reopened and is thriving–another indication of the resurgence of US manufacturing, reports The New York Times (Sept. 20, 2013) in its cover story. For example, just last year, clothing maker American Giant was buying fabric from a factory in India. Now, it is cheaper to shop in the US, using Parkdale yarn.

American manufacturing has several advantages over outsourcing. Transportation costs are a fraction of what they are overseas. Turnaround time is quicker. Most striking, labor costs aren’t that much higher than overseas because the factories that survived the outsourcing wave have turned to automation and are employing far fewer workers. Further, monitoring worker safety in places like Bangladesh, has become a huge challenge.

In 2012, textile exports were $22.7 billion, up 37% from just 3 years earlier. That the industry is thriving again is indicative of a broader reassessment by companies about manufacturing in the US. A recent M.I.T. survey found that 1/3 of American companies with manufacturing overseas said they were considering backsourcing some production, while 15% said they had already decided to do so. This means jobs–but on nowhere near the scale there was before, because machines have replaced humans at almost every point in the production process. Take Parkdale: The mill produces 2.5 million pounds of yarn a week with about 140 workers. In 1980, that production level would have required more than 2,000 people.
