The Airline and Global Reservation Systems is a major user of flight codes to airports and airlines all over the world and will definitely attest to its importance in guiding and controlling hundreds to thousands of global flights. With about nine thousand fully operational flight codes presently used by airports and airlines, there really ought to be codes to easily identify and distinguish one from the other. Whether the airport is a domestic or international one, and the airline is a local, regional or cuts across international skies, there is a unique code that each one of them possesses and this makes it easy for airport staff, pilots and some frequent flying passengers to recognize from the hundreds of daily and weekly flight schedules they handle. Therefore flight codes comprising of both airline and airport codes are simple ideas with great importance.

Almost all flight codes are either two or three significant letters and numbers. Sometimes they are used on luggage that indicates the airports of departure and arrival with the airline’s code also attached. Apart from being used as luggage tags, these codes are also used on air tickets for airport security and check-in staff to easily make reference to. For example, in modern airports, passengers just need to check the digital monitors or screens that have been strategically positioned within the halls, to know where their next flight is heading to. Thanks to these codes which have shortened some otherwise lengthy airport names. To compare with the codes on their air tickets and boarding passes is easy to do when they have seen the information indicated with the flight codes.

Flight codes carry important and valuable information that makes it easier to trace flights or track the progress of a flight but merely looking at the codes, they may not make sense to the average passenger. Because they are in their thousands, they need to be stored within each airline or airport’s database. Therefore there is a need to shorten them for stress-free reference and retrieval, even for the printing out of paper tickets. The alphabetic, alpha-numeric or codes apply to every country in the world; talking about countries which participate in global exchange of flights and is part of the International Air Transport Association (IATA). Flight codes are relatively stable and will not change significantly for a fairly long time.

Being an acceptable format of identification in the aviation industry, flight codes are also seen as a shorthand way of writing the entire name of an airport or airline; and a short form of making reference to an airline as well. Singapore’s Changi Airport can comfortably be called SIN. Tourists to the desert city of Dubai’s International Airport usually refer to it as DBX while Lagos’ Murtala International Airport in Nigeria is mostly pronounced by expatriate travelers to the country as LOS. Among airlines, it is not uncommon to find any two or three of the airline’s names being used as part of its flight code. There are many other airports and airlines around the world which carry their own distinct brand nickname which is also their flight code. Strictly speaking, it conforms to the growing pattern of globalization involving almost all spheres of endeavor, and in which the world is tending to.

Other types of codes which apply to flights are promotional codes. Also called flight coupon codes, these are just the rebates or discounts given to passengers by airlines or travel agents to encourage their patronage. Flight coupon codes can be got from different ways especially through early flight booking. In a situation where a passenger does not have enough to pay for a one-way or return flight ticket, the best thing to do is to look for a cheap discount offer as there will always be one; except if the destination is not too popular among airline routes. There may also be rewards as coupon codes for passengers who refer others to an airline or Travel Company, and these codes do reduce the overall cost of a flight ticket. Great discounts on airfares abound and are made available to passengers who are smart enough to strike the deals when the iron is still hot.
