In the aviation industry, the flight number or flight determiner is the code for the flight service consisting of two airline defining characters and 1 to 4 digit numbers. For example, "KL 445" is the KLM service from Amsterdam to Kuwait. The service is called "direct" if it is covered by a single flight number, regardless of the number of stops or equipment changes. For example, "WN 417" flies from Jacksonville to Baltimore to Oakland to Los Angeles. Certain flight segments may have multiple flight numbers on different airlines under a code-sharing agreement. Actually, the flight number is just a numerical part, but is usually used for all flight bookmarks.
Flight determinants of commercial aviation operation operators are used as callsign. This differs from the aircraft registration number, which identifies a particular aircraft.

Convention
A number of conventions have been developed to determine flight numbers, though this varies greatly from airline to airline, and is increasingly modified. Flights east and north are traditionally numbered even, while flights to the west and south have odd numbers. Other airlines will use the odd number for outbound flights and use the next even number for the return flight backwards. For the purposes served by several flights per day, the numbers tend to increase during the day. Therefore, flights from point A to point B may flight 101 and return flight from B to A will be 102, while the next flight pairs on the same route will normally be coded 103 and 104.
Less than three-digit flight numbers are often assigned to long-haul flights or premium flights. Flight number 1 is often used for airline "flagship" services. For example, the British Airways 1 flight is a morning Concorde supersonic service from London to New York City and is now a premium business class flight just among the same cities; Air New Zealand 1 flights are daily services from London to Auckland via Los Angeles; Qantas 1 Flight is the daily Kangaroo Route from Sydney via Dubai to London. American Airlines Flight 1 is a daily flight from New York to Los Angeles; United Airlines Flight 1 is a daily flight from San Francisco to Singapore; and El Al flight 1 is a daily flight service from Tel Aviv to New York City.
Four-digit numbers in the range 3000 to 5999 typically represent regional affiliate flights, while numbers greater than 6000 are generally codeshare numbers for flights operated by different airlines or even trains.
Likewise, flights greater than 9000 typically refer to ferry flights; this does not carry passengers and is used to relocate the aircraft to or from a maintenance base, or from one air travel market to another to start a new commercial flight. Flight numbers beginning with 8 are often used for charter flights, but always depend on the choice of commercial carrier.
Maps Flight number
In codeshare, airlines distribute their planes with other airlines, so the flight has more than one flight number in the same sector, and either the same or different flight numbers in the sector that joins.
For example hypothetically, QQ1234 flight can fly from AAA airport to BBB to CCC. The AAA-BBB segment can be served by QQ airlines, and the BBB-CCC segment by RR airlines, on different planes. The same flight can also be sold as RR3210, and by the third SS carrier as SS2345. Also, each flight leg may have several flight numbers: AAA-BBB may be QQ12, RR23, and SS45.
For example, flight Alaska Airlines AS61 in June 2018 flying from Juneau (JNU) to Yakutat (YAK) to Cordova (CDV) to Anchorage (ANC). Tickets for Yakutat to Anchorage segment are designated as AS61 YAK-ANC. It is even possible for a given flight number to close the initial order and end at the same airport.
List flight number 1 by airline
Most non-stop flights from A to B, and some from A to B then to C (both A-B and B-C have flight number 1). The type of aircraft may change due to operating requirements.

Change of flight number
Flight numbers are often not used after an accident or serious incident. For example, after the Alaska Airlines Flight 261 accident, the airline changed its flight number for the next flight following the same route to 229. Also, American Airlines Flight 77, which regularly flew from Dulles International Airport in Washington, DC, to Los Angeles International Airport, became Flight 149 after the September 11 attacks. On the other hand, other considerations may cause the airline not to change the flight number; for example, the American Airlines Flight 1 aircraft mentioned above defended its appointment despite major accidents in 1962. There are at least four examples of flight numbers having two serious accidents: Flight 253 from Linea Aeropostal Venezolana (both in 1956, first in June, and the second in November), Flight 869 from United Arab Airlines (the first in 1962 and the second in 1963), Flight 800 from TWA (the first in 1964 and the second in 1996), and Flight 383 of American Airlines (the first in 1965 and the second in 2016). Another example of this is retirement from both MH370 and MH371 after the aircraft disappears in 2014.
Flight number preservation
The incorporation of mega aircraft, in markets like the United States, has made it necessary to break the conventional flight numbering scheme. Organizations such as IATA, ICAO, ARC, and CRS systems and ATC FAA systems limit flight numbers to four digits (0001 to 9999). The number of available flights has exceeded their demand with the appearance of large aircraft carriers. Thus, some operators use the same flight number for alternating flights (eg DCA-PBI-DCA), or in other cases the operator has assigned one flight number to the multi-leg flight (eg ICT-DAL-HOU -MDW-OMA -DEN-ABQ-LAS-BDL).
Airplane marker
Note that, although 'flight number' is a term used in everyday language, the official term as defined in the Standard Schedule Information Manual (SSIM) published annually by the International Air Transport Association's Standards of Standards Standards Committee (SISC), is flight pointer . Officially the term 'flight number' refers to the numeric (up to four digits) portion of the flight code. For example, in the BA2490 and BA2491A flight codes, "2490" and "2491" are flight numbers. Even in the aviation and airport industries, it is common to use the term daily rather than the official term.
Spacecraft
Flight numbers are also sometimes used for spacecraft, although flight numbers for disposable rockets (eg, Ariane 5 Flight 501) may be more worth mentioning as vehicle serial numbers used, because disposable rockets can only be launched once. Space Shuttle missions use numbers with STS prefixes, for example, STS-93.
