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 Transport hub, 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, Lion Air and VietJet Air, 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" airport where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Point To Point Vs Hub And Spoke
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and the arts. General usage Comparison is a natural activity, which even animals engage in when decidin ...

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 act gradually phased out and disbanded the Civil Aeronautics Board (CAB), but the regulatory powers of the Federal Aviation Administration (FAA) over all aspects of aviation safety were not diminished. History Since 1938, the federal 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 rate of ret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 alw ...

2022 Southwest Airlines Scheduling Crisis
In December 2022, Southwest Airlines, a major U.S. airline, and the third largest by domestic passenger volume, canceled more flights than usual, including more than 60% of its flights on two days. The crisis spanned December 21–30, at the peak of the holiday travel season, and is referred to in the news media as the Southwest Airlines holiday travel meltdown or simply as the holiday meltdown, a name also used by the Southwest Airlines pilot's union and the U.S. Department of Transportation. The disruption to operations was described by ''Seeking Alpha'' as the most costly and largest in the history of U.S. airlines. More than 15,000 flights were canceled throughout the crisis. On December 18, 2023, Southwest was fined $140 million by the U.S. Department of Transportation, surpassing the highest previous fine in the agency's history by a factor of about 30. As of that date, Southwest had paid about $600 million in reimbursement to passengers, and reported losses of $1.1 billio ...

Permutation
In mathematics, a permutation of a set can mean one of two different things: * an arrangement of its members in a sequence or linear order, or * the act or process of changing the linear order of an ordered set. An example of the first meaning is the six permutations (orderings) of the set : written as tuples, they are (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). Anagrams of a word whose letters are all different are also permutations: the letters are already ordered in the original word, and the anagram reorders them. The study of permutations of finite sets is an important topic in combinatorics and group theory. Permutations are used in almost every branch of mathematics and in many other fields of science. In computer science, they are used for analyzing sorting algorithms; in quantum physics, for describing states of particles; and in biology, for describing RNA sequences. The number of permutations of distinct objects is factorial, us ... [...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 o ...

Alps
The Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia. The Alpine arch extends from Nice on the western Mediterranean Sea, Mediterranean to Trieste on the Adriatic Sea, 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 thrust fault, thrusting and Fold (geology), 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 82 peaks higher than List of Alpine four-thousanders, . The altitude and size of the range affect the climate in Europe; in the mountain ... [...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 east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. 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. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, 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 sea was an important ... [...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] |
