Domestic air transport grew in China at 15.5 percent annually from 2001 to 2006. The rate of air travel globally increased at 3.7 percent per year over the same time. In the EU greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[75] However it must be compared with the flights increase, only in UK, between 1990 and 2006 terminal passengers increased from 100 000 thousands to 250 000 thousands.,[76] according to AEA reports every year, 750 million passengers travel by European airlines, which also share 40% of merchandise value in and out of Europe.[77] Without even pressure from "green activists", targeting lower ticket prices, generally, airlines do what is possible to cut the fuel consumption (and gas emissions connected therewith). Further, according to some reports, it can be concluded that the last piston-powered aircraft were as fuel-efficient as the average jet in 2005.[78]

Hi Dave! Your website is so detailed and helpful! I’m starting to plan a trip for late May-early June. We were interested in visiting Santorini, Naxos (we opted for Naxos instead of party-filled Mykonos) and Milos. Our main airport of arrival is Athens. What order should we visit all three islands (in terms of convenience of ferry/flight availability) and how many nights do you recommend allotting to each? Thanks in advance for your time!
One argument is that positive externalities, such as higher growth due to global mobility, outweigh the microeconomic losses and justify continuing government intervention. A historically high level of government intervention in the airline industry can be seen as part of a wider political consensus on strategic forms of transport, such as highways and railways, both of which receive public funding in most parts of the world. Although many countries continue to operate state-owned or parastatal airlines, many large airlines today are privately owned and are therefore governed by microeconomic principles to maximize shareholder profit.
Java, with a population of 140 million, makes its first appearance on this list. Celebrated for its ancient culture, breathtaking vistas, and UNESCO World Heritage sites like the Borobudur Temple Compounds, the island also offers the opportunity to indulge in modernity (five-star hotels abound). Waterfalls, volcanoes, protected parks, and white-sand beaches also allow visitors to get away from the thrum.
Increasingly since 1978, US airlines have been reincorporated and spun off by newly created and internally led management companies, and thus becoming nothing more than operating units and subsidiaries with limited financially decisive control. Among some of these holding companies and parent companies which are relatively well known, are the UAL Corporation, along with the AMR Corporation, among a long list of airline holding companies sometime recognized worldwide. Less recognized are the private equity firms which often seize managerial, financial, and board of directors control of distressed airline companies by temporarily investing large sums of capital in air carriers, to rescheme an airlines assets into a profitable organization or liquidating an air carrier of their profitable and worthwhile routes and business operations.
We are planning our honeymoon in Greece. We can probably take up to two weeks. One of the places we want to go is Santorini. We would like to visit one or maybe two other places if possible. The other places we were looking at are Athens, Mykonos & Crete. Which of these would you recommend with Santorini if we were thinking of visiting 2 or 3 places total?
Lefkada is the island that’s not an island. You can drive to it across the causeway from the mainland, but it feels every bit an island. Aristotle Onassis bought the satellite island of Skorpios here as his own bit of getaway paradise. Beaches, windsurfing, boat hire, good food and wine are all here and there are few built-up package resorts. The main tourist area is centred on Nydri.
Barbados is a vibrant island with a great nightlight. Bridgetown is one of the nightlife capitals of the area, so if you’re looking to stay up until the wee hours then this might be the island for you! Like Bermuda, you’ll find amazing beaches and caving here. You’ll also find some world-class surfing. The food here is amazing, and you’ll be able to enjoy expensive, delicious meals alongside cheap local food.
You seem to have your heart set on Zakynthos but I have to say it’s not a good use of time for a sort-of overrated payoff. Your time is much better spent (in my opinion) seeing another Greek island in the cyclades (maybe taking a ferry to Naxos or Paros sitting outside on the deck drinking a bottle of wine) rather than taking a bus and connecting flights. Zakynthos and Santorini/Mykonos are on opposite sides of the country and the only way from one to the other is by flying (or some combination of bus and ferry). So, my recommendation is to consider spending those Zakynthos days in Naxos, Paros, Milos, or some other Cycladic island.
That all sounds good though I would recommend Naxos over Mykonos in March as there’s more to see and do there when not beach weather. And if you do decide to do Mykonos be sure there’s a ferry from Mykonos to Santorini for your dates. And same for Santorini to Crete. There should be ferry service but the route starts different times every year so you do want to be certain. 

Germany's Deutsche Luft Hansa was created in 1926 by merger of two airlines, one of them Junkers Luftverkehr. Luft Hansa, due to the Junkers heritage and unlike most other airlines at the time, became a major investor in airlines outside of Europe, providing capital to Varig and Avianca. German airliners built by Junkers, Dornier, and Fokker were among the most advanced in the world at the time.
