The airline industry has no future. The same is true for airfreight. No air carrier has a viable plan to make a profit with oil at current prices—much less in years to come as the petroleum available to world markets dwindles rapidly.
That’s not to say that jetliners will disappear overnight, but rather that the cheap flights we’ve seen in the past will soon be fading memories. In a few years jet service will be available only to the wealthy, or to the government and military.
Sir Richard Branson of Virgin Atlantic says he wants to use biofuels to power his fleet of 747’s and Airbuses. There are still some bugs to be worked out in terms of basic chemistry, but it might be possible in principle—if only we could make enough biodiesel or ethanol without further driving up food prices and wrecking the soil. Even then it would be very costly fuel.
Are there other options for powered flight?
Hydrogen could be burned in jet engines, but doing so would require a complete redesign of our commercial aircraft fleet, and H2 would be expensive to make—unless the growing trend toward more costly electricity (as we phase out depleting, polluting coal and increasingly scarce natural gas) can somehow be reversed.
Last year I was invited to give the keynote address at the world’s first Electric Aircraft Symposium. NASA and Boeing sent representatives, but all told there were only about 20 in attendance. The planes being discussed were ultralight two-seaters: that’s the limit of current or foreseeable battery technology. These might come in handy in a future where they are the only option for emergency air travel (blimps need depleting helium or explosive hydrogen). But forget about 300-seat planes running on solar or wind power, ferrying middle-class vacationers to Bali or Venice.
There are good reasons to cut down on air travel voluntarily: flying not only swells our personal carbon emissions but spews CO2 and other pollutants into the stratosphere, where they do the most damage. However, the worsening scarcity of the stuff we use for making jet fuel takes the discussion out of the realm of optional moral action and into that of economic necessity and personal adaptation.
I fly to educate both general audiences and policy makers about fossil fuel depletion; in fact, I’m writing this article aboard a plane en route from Boston to San Francisco. I wince at my carbon footprint, but console myself with the hope that my message helps thousands of others to change their consumption patterns. This inner conflict is about to be resolved: the decline of affordable air travel is forcing me to rethink my work. I’m already starting to do much more by video teleconference, much less by jet.
Those who live far from family will be more than inconvenienced, as will the hundreds of thousands who work for the airline industry directly or indirectly, or the millions who depend on tourism or airfreight for an income. These folks will have few options: teleconferencing can accomplish only so much.
Our species’ historically brief fling with flight has been fun, educational, and enriching on many levels to those fortunate enough to benefit from it. Saying goodbye will be difficult. But maybe as we do we can say hello to greater involvement in our local communities.

Absent any significant new
Airships are the future
Zeppelins....where do we get
Back to the Future
I don't even see the rich flying much
It's premature to call the death of the airline industry.
Saying Goodbye!
Zeppelins, no

British engineers have unveiled plans for a hypersonic jet which could fly from Europe to Australia in less than five hours.
The A2 plane, designed by engineering company Reaction Engines based in Oxfordshire, southern England, could carry 300 passengers at a top speed of almost 6,400 kilometres per hour - five times the speed of sound.
The LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) project, backed by the European Space Agency, could see the plane operating within 25 years, the firm's boss Alan Bond told the Guardian daily.
"The A2 is designed to leave Brussels international airport, fly quietly and subsonically out into the north Atlantic at mach 0.9 before reaching mach 5 across the North Pole and heading over the Pacific to Australia," he said.
The plane, which at 143 metres long would be about twice the size of the biggest current jets, could fly non-stop for up to 20,000 kilometres.
It operates on liquid hydrogen, which is more ecologically friendly as it gives off water and nitrous oxide instead of carbon emissions.
Passengers would have to put up with having no windows, due to problems with heat produced at high speeds.
Instead, designers may put flat screen televisions where the windows would be, giving the impression of seeing outside.
Fares would be comparable with current first class tickets on standard flights.
The flight time from Brussels to Australia would be four hours and 40 minutes.
"It sounds incredible by today's standards but I don't see why future generations can't make day trips to Australasia," Mr Bond said.
"Our work shows that it is possible technically; now it's up to the world to decide if it wants it."
