Lufthansa in the context of "Catania Airport"

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.

The Boeing 737 is an American narrow-body aircraft produced by Boeing at its Renton factory in Washington.Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines. Envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered service in February 1968 with Lufthansa.The lengthened 737-200 entered service in April 1968, and evolved through four generations, offering several variants for 85 to 215 passengers.

The first generation 737-100/200 variants were powered by Pratt & Whitney JT8D low-bypass turbofan engines and offered seating for 85 to 130 passengers. Launched in 1980 and introduced in 1984, the second generation 737 Classic -300/400/500 variants were upgraded with more fuel-efficient CFM56-3 high-bypass turbofans and offered 110 to 168 seats. Introduced in 1997, the third generation 737 Next Generation (NG) -600/700/800/900 variants have updated CFM56-7 high-bypass turbofans, a larger wing and an upgraded glass cockpit, and seat 108 to 215 passengers. The fourth and latest generation, the 737 MAX -7/8/9/10 variants, powered by improved CFM LEAP-1B high-bypass turbofans and accommodating 138 to 204 people, entered service in 2017.Boeing Business Jet versions have been produced since the 737NG, as well as military models.

In aviation, aircraft ground handling or ground operations defines the servicing of an aircraft while it is on the ground and (usually) parked at a terminal gate of an airport.

Germanwings GmbH was a German low-cost airline wholly owned by Lufthansa which operated under the Eurowings brand. It was based in Cologne with hubs at Cologne Bonn Airport, Stuttgart Airport, Hamburg Airport, Berlin Tegel Airport, and Munich Airport; and further bases at Hannover Airport and Dortmund Airport.

Germanwings operated independently as Lufthansa's low-cost carrier until October 2015, when Lufthansa decided to fully transfer the brand identity of its low cost short haul-product to Eurowings. After 2016, Germanwings operated as a wet lease operator for its sister company Eurowings, with the Germanwings branding being phased out. The IATA code 4U continued to operate under the Eurowings brand until March 2018, when it was abandoned and replaced with the Eurowings designator EW. Germanwings was closed and merged back into Eurowings in April 2020 as part of a broad restructuring during the COVID-19 pandemic.

Material handling involves short-distance movement within the confines of a building or between a building and a transportation vehicle. It uses a wide range of manual, semi-automated, and automated equipment and includes consideration of the protection, storage, and control of materials throughout their manufacturing, warehousing, distribution, consumption, and disposal. Material handling can be used to create time and place utility through the handling, storage, and control of waste, as distinct from manufacturing, which creates form utility by changing the shape, form, and makeup of material.

A shared services center – a center for shared services in an organization – is the entity responsible for the execution and the handling of specific operational tasks, such as accounting, human resources, payroll, IT, legal, compliance, purchasing, security. The shared services center is often a spin-off of the corporate services to separate all operational types of tasks from the corporate headquarters, which has to focus on a leadership and corporate governance type of role. As shared services centers are often cost centers, they are quite cost-sensitive also in terms of their headcount, labour costs and location selection criteria.

In the United States, a legacy carrier is an airline that was once economically regulated by the Civil Aeronautics Board (CAB) during the period of airline regulation 1938–1978 or can trace its origin to one that did. The CAB was a now defunct federal agency that tightly controlled almost all US commercial air transport during that period. As related below, many features associated with the legacy airline business model were actually developed not during the regulated era, but instead in the first decade or so of the deregulated era, as legacy carriers adapted to an unfamiliar competitive environment.

While the term "legacy carrier" is most often used in a US context, it is possible to speak of legacy carriers elsewhere, since tight airline regulation was once the global norm and following US airline deregulation, many other countries went through some kind of airline deregulation. Non-US carriers with origins that precede liberalization can be viewed as legacy carriers. For instance, in Europe, flag carriers such as British Airways, Air France, KLM, Iberia, and Lufthansa, (with origins well before the liberalized era) can be viewed as legacy carriers in contrast to airlines such as Ryanair, EasyJet, Wizz Air, and so forth.
