Point-to-point Transit
Point-to-point transit is a transportation system in which a plane, bus, or train travels directly to a destination, rather than going through a central hub. This differs from the spoke-hub distribution paradigm in which the transportation goes to a central location where passengers change to another train, bus, or plane to reach their destination. Use in airlines The point-to-point model is used widely by low-cost carriers, including Allegiant Air and Southwest Airlines in the U.S., and European carriers such as Ryanair, easyJet and Wizzair, along with some low-cost carriers in Asia like AirAsia, NokScoot, Thai Smile, and Tigerair Australia, for example. Many such airlines sell each flight leg independently and have no concept of round-trip ticketing or connecting flights so baggage must be collected and rechecked even to transfer between flights booked at the same time on the same airline. Although there are many point-to-point airlines, most have at least a "homebase" airpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Hub
A transport hub is a place where passengers and cargo are exchanged between vehicles and/or between transport modes. Public transport hubs include railway stations, rapid transit stations, bus stops, tram stops, airports and ferry slips. Freight hubs include classification yards, airports, seaports and truck terminals, or combinations of these. For private transport by car, the parking lot functions as a unimodal hub. History Historically, an interchange service in the scheduled passenger air transport industry involved a "through plane" flight operated by two or more airlines where a single aircraft was used with the individual airlines operating it with their own flight crews on their respective portions of a direct, no-change-of-plane multi-stop flight. In the U.S., a number of air carriers including Alaska Airlines, American Airlines, Braniff International Airways, Continental Airlines, Delta Air Lines, Eastern Airlines, Frontier Airlines (1950-1986), Hughes Airwest, ...

Civil Aeronautics Board
The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1938 and abolished in 1985, that regulated aviation services including scheduled passenger airline serviceStringer, David H."Non-Skeds: The Story of America’s Supplemental Airlines, Part 1: Industry in the United States,"'' AAHS Journal'', vol. 64, no.4 (Winter 2019) journal of the American Aviation Historical Society, excerpt online, retrieved April 8, 2020 and provided air accident investigation. The agency headquarters were in Washington, D.C. Functions The primary role of the CAB was to regulate scheduled commercial airline operations in the United States. The CAB strictly controlled all U.S. certificated airlines ("scheduled carriers") -- deciding which routes would be serviced by which airlines, and setting minimum limits on passenger fares (comparable to the Interstate Commerce Commission) -- effectively managing competition between airlines, and ensuring certain l ...

Direct Flight
A direct flight in the aviation industry is any flight between two points by an airline with no change in flight numbers, which may include one or more stops at an intermediate point(s). A stop may either be to get new passengers (or allow some to disembark) or a technical stop over (''i.e.'', for refuelling). Direct flights are often confused with non-stop flights, which are a special case of direct flights involving no intermediate stops. When there is a change in flight number, the subsequent flight is referred to as a connecting flight. General aspects The term "direct flight" is not legally defined in the United States, but since the 1970s the ''Official Airline Guides'' have defined the term simply as a flight(s) with a single flight number. (In earlier years "direct" in the OAG did mean "no plane change".) While so-called "direct" flights may thus involve changes in aircraft (a "change of gauge"), or even airline at the intermediate point, they are typically—but not al ...

Permutation
In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set. Permutations differ from combinations, which are selections of some members of a set regardless of order. For example, written as tuples, there are six permutations of the set , namely (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). These are all the possible orderings of this three-element set. Anagrams of words whose letters are different are also permutations: the letters are already ordered in the original word, and the anagram is a reordering of the letters. The study of permutations of finite sets is an important topic in the fields of combinatorics and group theory. Permutations are used in almost every branch of mathematics, and in many other fields of scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Cargo
Air cargo is any property carried or to be carried in an aircraft. Air cargo comprises air freight, air express and airmail. Aircraft types Different cargo can be transported by passenger, cargo or combi aircraft: * Passenger aircraft use the spare volume in the airplane's baggage hold (the "belly") that is not being used for passenger luggage—a common practice used by passenger airlines, who additionally transport cargo on scheduled passenger flights. Cargo can also be transported in the passenger cabin as hand-carry by an “on-board courier”. This practice can often be used to cross subsidise loss-making passenger routes that would otherwise be uneconomical to operate. A passenger aircraft can also be used as a preighter in which the entire passenger cabin is temporarily dedicated to carrying freight. * Cargo aircraft are dedicated for the job—they carry freight on the main deck and in the belly by means of nose-loading or side loading. * Combi aircraft carry cargo ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. The Mediterranean Sea e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focus City
An airline hub or hub airport is an airport used by one or more airlines to concentrate passenger traffic and flight operations. Hubs serve as transfer (or stop-over) points to help get passengers to their final destination. It is part of the hub-and-spoke system. An airline may operate flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities connect through the hub. This paradigm creates economies of scale that allow an airline to serve (via an intermediate connection) city-pairs that could otherwise not be economically served on a non-stop basis. This system contrasts with the point-to-point model, in which there are no hubs and nonstop flights are instead offered between spoke cities. Hub airports also serve origin and destination (O&D) traffic. Operations The hub-and-spoke system allows an airline to serve fewer routes, so fewer aircraft are needed. The system also increases passenger loads; a flight from a hub to a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1978 Airline Deregulation Act
The Airline Deregulation Act is a 1978 United States federal law that deregulated the airline industry in the United States, removing federal control over such areas as fares, routes, and market entry of new airlines. The Civil Aeronautics Board's powers of regulation were phased out, but the regulatory powers of the Federal Aviation Administration (FAA) were not diminished over all aspects of aviation safety. History Since 1938, the federal Civil Aeronautics Board (CAB) had regulated all domestic interstate air transport routes as a public utility, setting fares, routes, and schedules. Airlines that flew only intrastate routes, however, were not regulated by the CAB but were regulated by the governments of the states in which they operated. One way that the CAB promoted air travel was generally attempting to hold fares down in the short-haul market, which would be subsidized by higher fares in the long-haul market. The CAB also had to ensure that the airlines had a reasonable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tigerair Australia
Tiger Airways Australia Pty Ltd, operating as Tigerair Australia, was an Australian low-cost airline. Founded by Tiger Airways Holdings, it commenced services in the domestic airline market on 23 November 2007 as Tiger Airways Australia. It later became a subsidiary of Virgin Australia Holdings. On 25 March 2020, Tigerair suspended all operations as a result of the COVID-19 pandemic. Following Virgin Australian Holdings going into voluntary administration and later sold, new owner Bain Capital confirmed the brand would be retired. History Australian government policy and legislation currently permits airlines that are 100% foreign-owned to operate domestic airline services within the country. The change in regulations originally applied only to New Zealand-owned airlines in 1996, but were later relaxed, resulting in the establishment of Virgin Australia. Australian international airlines are still subject to ownership rules that limit foreign ownership to 49%. The Fore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
