A complicating factor is that of origin-destination control ("O&D control"). Someone purchasing a ticket from Melbourne to Sydney (as an example) for A$200 is competing with someone else who wants to fly Melbourne to Los Angeles through Sydney on the same flight, and who is willing to pay A$1400. Should the airline prefer the $1400 passenger, or the $200 passenger plus a possible Sydney-Los Angeles passenger willing to pay $1300? Airlines have to make hundreds of thousands of similar pricing decisions daily.
I’m a little worried I’ll get bored in Milos. My husband likes to stay in one place, but I like exploring. We would have split our time more evenly but we want to stay on the caldera and it’s just too expensive to stay any longer than two or three nights. Alternatively, we could stay in Santorini for longer but move to a cheaper hotel. Perhaps Santorini 6 nights and Milos 6 nights?
Christened the Garden Island, Kauai’s splendor extends from its vermillion Waimea Canyon, plunging down 3,600 feet, to its rugged Napali Cliffs, stretching up 4,000 feet. Often dotted with dozing monk seals, Kauai’s Poipu Beach has appeared on Dr. Beach’s esteemed list of America’s Best Beaches. Rivers, rainforests and waterfalls garnish the interior; don’t miss a photo op of Wailua Falls, famously featured in the opening credits of Fantasy Island, which aired from 1977 to 1984.
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.
