Not airtravel as we know it but would it be an alternative?

Yes it would, and that's what we'll see. Aircraft of the future will be very slow, but extremely fuel-efficient. The only fly in the oitment would be their vulnerability to bad weather. Jets just fly over or around it. Airships or very slow airplanes can't do that.
Actually you can build a rigid airship ala the Hindenberg with sufficient lifting power to go higher than the thunderheads and cost along quite nicely in the jet stream. There have been Ballon competitions for a decade or so trying to circumnavigate the world, without propulsion. Add engines and you can effectively go at a pretty fast clip with little energy wasted, especially if you lower your bouyancy by compressing the lifting gas into a tank instead of venting it.

Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

$this->bbcode_second_pass_quote('dbuckley', 'I') was born in NZ in the late 50s, and my mum "popped home" with me for a holiday to show me off to the grandparents in old England. Given the distinct lack of wide bodied jets and cheap airfairs, the journey took six weeks by boat. And six weeks back.
Expect to see a resurgence in sea travel, but powered by sail rather tha fuel oil...

You know Newport News shipbuilders has had quite a cusseful line of 100,000 ton ships that steam at 38 knots without without burning any petroleum in the process......
Look in Google under the USS Ronald Reagan
From this vantage point you can see that a fast passanger ship could easily be built as the finished product.

On December 22, 2003 Cunard officially launched its first new cruse ship built in 34 years. The $800 million Queen Mary 2 is the longest, tallest, widest and heaviest passenger ship ever constructed. The ship measures 1138.5 feet (345 meters) long, 135.3 feet (41 meters) wide, 237.6 meters (72 meters) tall, and weighing some 150,000 tonnes. The ship accomodates 2,630 passengers and features five swimming pools, 14 restaurants, 24 massage parlors and an art gallery.
