You’d have to check the schedule for your specific dates but I think Santorini then Milos then Paros then Naxos and Athens would probably be the best order. 3 days in each sounds great. Or a small tweak: 2 days in Milos and then 4 days in Santorini (splitting time between 2 of the 4 caldera towns) or even 4 days in Paros (splitting time between Naousa and Parikia).
Yes, it’s possible. Get the SeaJet ferry from Athens to Mykonos. It should arrive at 9:30am or shortly after. You’ll have to hurry to store you’re luggage at the Sea and Sky travel agency across from the Old Port and then buy tickets for Delos. The last ferry to Delos leaves at 11am or maybe 11:30am. Ferry to Delos is about 30 minutes. Last ferry back is at 3pm which will give you plenty of time before the last ferry of the day to Naxos (at 6:15pm on SeaJet). All the ferries mention here use the Old Port. Don’t book any ferries that use the New Port or you’ll have trouble making the connections.
A second financial issue is that of hedging oil and fuel purchases, which are usually second only to labor in its relative cost to the company. However, with the current high fuel prices it has become the largest cost to an airline. Legacy airlines, compared with new entrants, have been hit harder by rising fuel prices partly due to the running of older, less fuel efficient aircraft.[45] While hedging instruments can be expensive, they can easily pay for themselves many times over in periods of increasing fuel costs, such as in the 2000–2005 period.
Only two airlines - Avianca and LATAM Airlines - have international subsidiaries and cover many destinations within the Americas as well as major hubs in other continents. LATAM with Chile as the central operation along with Peru, Ecuador, Colombia, Brazil and Argentina and formerly with some operations in the Dominican Republic. The AviancaTACA group has control of Avianca Brazil, VIP Ecuador and a strategic alliance with AeroGal.
Operating costs for US major airlines are primarily aircraft operating expense including jet fuel, aircraft maintenance, depreciation and aircrew for 44%, servicing expense for 29% (traffic 11%, passenger 11% and aircraft 7%), 14% for reservations and sales and 13% for overheads (administration 6% and advertising 2%). An average US major Boeing 757-200 flies 1,252 mi (2,015 km) stages 11.3 block hours per day and costs $2,550 per block hour : $923 of ownership, $590 of maintenance, $548 of fuel and $489 of crew; or $13.34 per 186 seats per block hour. For a Boeing 737-500, a low-cost carrier like Southwest have lower operating costs at $1,526 than a full service one like United at $2,974, and higher productivity with 399,746 ASM per day against 264,284, resulting in a unit cost of 0.38 $cts/ASM against 1.13 $cts/ASM.[71]
Each operator of a scheduled or charter flight uses an airline call sign when communicating with airports or air traffic control centres. Most of these call-signs are derived from the airline's trade name, but for reasons of history, marketing, or the need to reduce ambiguity in spoken English (so that pilots do not mistakenly make navigational decisions based on instructions issued to a different aircraft), some airlines and air forces use call-signs less obviously connected with their trading name. For example, British Airways uses a Speedbird call-sign, named after the logo of its predecessor, BOAC, while SkyEurope used Relax.
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.
In 1926, Alan Cobham surveyed a flight route from the UK to Cape Town, South Africa, following this up with another proving flight to Melbourne, Australia. Other routes to British India and the Far East were also charted and demonstrated at this time. Regular services to Cairo and Basra began in 1927 and were extended to Karachi in 1929. The London-Australia service was inaugurated in 1932 with the Handley Page HP 42 airliners. Further services were opened up to Calcutta, Rangoon, Singapore, Brisbane and Hong Kong passengers departed London on 14 March 1936 following the establishment of a branch from Penang to Hong Kong.

The 1978 U.S. airline industry deregulation lowered federally controlled barriers for new airlines just as a downturn in the nation's economy occurred. New start-ups entered during the downturn, during which time they found aircraft and funding, contracted hangar and maintenance services, trained new employees, and recruited laid-off staff from other airlines.
Airline financing is quite complex, since airlines are highly leveraged operations. Not only must they purchase (or lease) new airliner bodies and engines regularly, they must make major long-term fleet decisions with the goal of meeting the demands of their markets while producing a fleet that is relatively economical to operate and maintain; comparably Southwest Airlines and their reliance on a single airplane type (the Boeing 737 and derivatives), with the now defunct Eastern Air Lines which operated 17 different aircraft types, each with varying pilot, engine, maintenance, and support needs.
Service during the early 1920s was sporadic: most airlines at the time were focused on carrying bags of mail. In 1925, however, the Ford Motor Company bought out the Stout Aircraft Company and began construction of the all-metal Ford Trimotor, which became the first successful American airliner. With a 12-passenger capacity, the Trimotor made passenger service potentially profitable.[29] Air service was seen as a supplement to rail service in the American transportation network.
Blaca Hermitage in the south of the island is a must-visit, as well as Vidova Gora Mountain, which is the highest peak on the island, offering you stunning views across the Adriatic and to neighboring islands on a clear day. Brač is also where you’ll find the famous Zlatni Rat Beach, one of the absolute best Croatia beaches (and even in all of Europe) and a wonderful place to spend a day. This all makes Brač one of the best islands near Split, a perfect day trip from Croatia’s second-largest city.
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.
