Crete, Santorini, and Naxos look quite doable within the 12-day block, but Crete’s beaches are scattered throughout a very LARGE island, Santorini really only has Kamari and Perissá (and some southern coast bays) and Naxos does have nice places to swim. If you choose only to visit those three islands in your relatively short time, you will do well.
The Greek islands have beautiful weather in the months just before and after peak season. It’s a great time to see the islands, save money, avoid the crowds, and still have great weather (though not as hot as July and August). If you want to see the super-popular islands of Santorini, Rhodes, Corfu, and Crete without the tourists then this is a great time to visit.
Many countries have national airlines that the government owns and operates. Fully private airlines are subject to a great deal of government regulation for economic, political, and safety concerns. For instance, governments often intervene to halt airline labor actions to protect the free flow of people, communications, and goods between different regions without compromising safety.
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.
Budgeting for Greece is always going to be subject to what your expectations and needs are. Assuming that you, like many travellers, like to eat a filling breakfast, savour maybe a light lunch and feast on a heavier dinner (or vice versa), enjoy a drink with your meals and are not totally vegetarian/vegan and prefer to sleep in comfort and cleanliness, then there is a set of figures that can be guesstimated.
A limestone spike rising dramatically from the emerald waters of Phang Nga Bay, James Bond Island (Koh Tapu — Nail Island in Thai) earned its moniker from appearing in two 007 movies: The Man with the Golden Gun (1974) and Tomorrow Never Dies (1997). Excursions depart from the popular resort areas of Phuket, Khao Lak and Krabi on photogenic longtail boats. On the tour, explore secret lagoons, craggy sea caves and a floating village.
DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft I was the world's first airline. It was founded on November 16, 1909, with government assistance, and operated airships manufactured by The Zeppelin Corporation. Its headquarters were in Frankfurt. The first fixed wing scheduled airline was started on January 1, 1914, from St. Petersburg, Florida, to Tampa, Florida. The four oldest non-dirigible airlines that still exist are Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1921), and the Czech Republic's Czech Airlines (1923).
Those are 3 great islands. Corfu is much more green than Crete and Santorini and does have a different feel (more Italian but it’s no where near Turkey). The trouble with doing all 3 is that Corfu is on the opposite side of Greece from Crete and Santorini so you’d need to fly via Athens. It’s better for most people to visit another Cycladic island (Naxos, Paros, Milos, Folegandros) instead of splitting up their trip between the two sides of the country.
In the 1990s, "open skies" agreements became more common. These agreements take many of these regulatory powers from state governments and open up international routes to further competition. Open skies agreements have met some criticism, particularly within the European Union, whose airlines would be at a comparative disadvantage with the United States' because of cabotage restrictions.
Also, if there are any other suggestions you have in general for Athens and Santorini I would love to hear them. I would like to be able to leave Athens early morning on Day 3 so that we can have almost a full day on our first island. We would like to see as much as we can without feeling like we are running around from island to island the whole time.
We’re on a budget (think €50 per person per day) and would like to go someplace warm and sunny where there’s also a combination of culture and nature. So we can explore in the mornings and relax at the beach in the afternoon. Preferably a sandy beach. We don’t need a lot of nightlife but it would be nice if not the whole island is closing down already. Do you have a suggestion?
Since airline reservation requests are often made by city-pair (such as "show me flights from Chicago to Düsseldorf"), an airline that can codeshare with another airline for a variety of routes might be able to be listed as indeed offering a Chicago–Düsseldorf flight. The passenger is advised however, that airline no. 1 operates the flight from say Chicago to Amsterdam, and airline no. 2 operates the continuing flight (on a different airplane, sometimes from another terminal) to Düsseldorf. Thus the primary rationale for code sharing is to expand one's service offerings in city-pair terms to increase sales.
It’s a tough call. The good news is that whatever you decide, it will feel like the right thing after you’ve done it. You’ll almost certainly say to yourself, “I’m so glad we saw both islands” or “I’m so glad we had 6 full days on Santorini.” In deciding I would ask whether a return trip to Greece is likely or possible in the next couple of years. If so, then spend your 6 days on Santorini and explore that island, then return to Crete at some time in the future for a deserving 7 to 10 days. But if this is a one-time deal for the foreseeable future then do 3 days on Santorini and 3 days in Crete. (Whatever you decide don’t do a day trip to the other island as it’s not worth the time and effort.)
If a particular city has two or more airports, market forces will tend to attract the less profitable routes, or those on which competition is weakest, to the less congested airport, where slots are likely to be more available and therefore cheaper. For example, Reagan National Airport attracts profitable routes due partly to its congestion, leaving less-profitable routes to Baltimore-Washington International Airport and Dulles International Airport.
Airlines follow a corporate structure where each broad area of operations (such as maintenance, flight operations (including flight safety), and passenger service) is supervised by a vice president. Larger airlines often appoint vice presidents to oversee each of the airline's hubs as well. Airlines employ lawyers to deal with regulatory procedures and other administrative tasks.
