Airline codes
–
This is a list of airline codes. The table lists IATAs two-character airline designators, ICAOs three-character airline designators, IATA airline designators, sometimes called IATA reservation codes, are two-character codes assigned by the International Air Transport Association to the worlds airlines. The standard is described in IATAs Standard Schedules Information Manual and the codes themselves are described in IATAs Airline Coding Directory, Airline designator codes follow the format xx, i. e. two alphanumeric characters followed by an optional letter. Although the IATA standard provides for three-character airline designators, IATA has not used the third character in any assigned code. This is because some legacy computer systems, especially the central reservations systems, have failed to comply with the standard, the codes issued to date comply with IATA Resolution 762, which provides for only two characters. These codes thus comply with the current airline designator standard, there are three types of designator, unique, numeric/alpha and controlled duplicate. IATA airline designators are used to identify an airline for commercial purposes in reservations, timetables, tickets, tariffs, air waybills, a flight designator is the concatenation of the airline designator, xx, and the numeric flight number, n, plus an optional one-letter operational suffix. Therefore, the format of a flight designator is xxn. After an airline is delisted, IATA can make the code available for reuse after six months, controlled duplicates are issued to regional airlines whose destinations are not likely to overlap, so that the same code is shared by two airlines. The controlled duplicate is denoted here, and in IATA literature, an example of this is the code 6Y, which refers to both Mid Airlines, a charter airline in Sudan, and Med Airways, a charter airline in Lebanon. IATA also issues an accounting or prefix code and this number is used on tickets as the first three characters of the ticket number. The IATA codes originally based on the ICAO designators which were issued in 1947 as two-letter airline identification codes and these codes are unique by airline, unlike the IATA airline designator codes. The designators are listed in ICAO Document 8585, Designators for Aircraft Operating Agencies, ICAO codes have been issued since 1947. The ICAO codes originally based on a two-letter-system and were identical to the codes used by IATA. After an airline joined IATA its existing ICAO-two-letter-code was taken over as IATA code, so in the 1970s the abbreviation BA was the ICAO code and the IATA code of British Airways while non-IATA-airlines like Court Line used their 2-letter-abbreviation as ICAO code only. In the early 1980s ICAO introduced the current three-letter-system due to the number of airlines. It became the new standard system in November 1987. Other designators, particularly starting with Y and Z, are reserved for government organizations

Focus city
–
In the airline industry, a focus city is a destination from which an airline operates several point-to-point routes. Thus, a city primarily caters to the local market rather than to connecting passengers. However, with the terms expanded usage, a city may also function as a small-scale hub. Allegiant Air, JetBlue and Frontier Airlines are examples of airlines that consider some of their destinations to be focus cities

Tupolev Tu-154
–
The Tupolev Tu-154 is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. It was exported to 17 non-Russian airlines and used as a transport by the air forces of several countries. With a cruising speed of 900 kilometres per hour the Tu-154 is one of the fastest civilian aircraft in use and has a range of 5,280 kilometres. Since 1968 there have been 39 fatal incidents involving the Tu-154, most of which were caused either by factors unrelated to the aircraft, following a crash in 2016 all Tupolev Tu-154 aircraft in Russia were grounded. However, the Tu-154 is still being used as of January 2017, the Tu-154 was developed to meet Aeroflots requirement to replace the jet-powered Tu-104, the Antonov An-10 and the Ilyushin Il-18 turboprops. A takeoff distance of 2,600 metres at maximum weight was also stipulated as a requirement. The Soviet Ministry of Aircraft Industry chose the Tu-154 as it incorporated the latest in Soviet aircraft design, the first project chief was Sergey Yeger, in 1964, Dmitryi S. Markov assumed that position. In 1975, the lead role was turned over to Aleksandr S. Shengardt. The Tu-154 first flew on 4 October 1968, the first deliveries to Aeroflot were in 1970 with freight services beginning in May 1971 and passenger services in February 1972. There was still limited production of the 154M model as of January 2009 despite previous announcements of the end of production in 2006,1025 Tu-154s have been built,214 of which were still in service as of 14 December 2009. The last serial Tu-154 was delivered to the Russian Defense Ministry on 19 February 2013 from the Aviakor factory, equipped with upgraded avionics, a VIP interior, the factory has four unfinished hulls in its inventory which can be completed if new orders are received. The Tu-154 is powered by three rear-mounted low-bypass turbofan engines arranged similarly to those of the Boeing 727, but it is larger than its American counterpart. Both the 727 and the Tu-154 use an S-duct for the middle engine, the original model was equipped with Kuznetsov NK-8-2 engines, which were replaced with Soloviev D-30KU-154 in the Tu-154M. All Tu-154 aircraft models have a relatively high thrust-to-weight-ratio which give excellent performance and this became an important factor in later decades as fuel costs grew. The flight deck is fitted with conventional dual yoke control columns, Flight control surfaces are hydraulically operated. The cabin of the Tu-154, although of the same six-abreast seating layout, gives the impression of an interior, with a lower ceiling than is common on Boeing. The passenger cabin accommodates 128 passengers in a layout and 164 passengers in single-class layout. The layout can be modified to what is called a winter version where some seats are taken out, the passenger doors are smaller than on its Boeing and Airbus counterparts
