How are flight numbers assigned?

As it turns out, flight numbers contain no special codes, other than the fact that they're generally assigned sequentially in order of flight departure time. They are usually assigned by an airline's marketing department.

I don't really know, but I have seen a fact:

American Airlines gives 2 digit flight numbers when going to London, and some airlines gives number for a round trip, for example, Mexicana flight MEX-JFK is number 2 and 4, and JFK-MEX are 1 and 3.

I don't think they are asigned timwise, because the 6AM flight would always be the flight number 1 and the 11:55PM would always be the 40, and it is not like that.

I think it works marketswise, as AA, Europe es 10-99, South America 700-750, Asia 1000-1100, I don't know!

Here is how u find it!

Aflight huge type , at the same time as mixed with the call of the airline and the date, identifies a particular flight. this can no longer be puzzled with the tail style of the plane . a particular plane would fly numerous diverse flights in a unmarried day, and diverse plane will be used for a similar flight huge type on successive days. distinctive conventions have enhanced for outlining flight numbers, inspite of the actual undeniable truth that those determination significantly from airline to airline. Eastbound and northbound flights are traditionally assigned even numbers , at the same time as westbound and southbound flights have wonderful numbers. For places served by ability of distinct flights in step with day, numbers have a tendency to improve in the course of the day. hence, a flight from element A to point B will be flight one hundred and one and the go back flight from B to A will be 102, at the same time as the subsequent pair of flights on a similar route would frequently be assigned codes 103 and 104. Flight numbers of decrease than 3 digits are frequently assigned to lengthy-haul or otherwise correct price flights. as an celebration, British airways flight a million replaced into the early morning supersonic Concorde service from London to ny city , and Air Canada flight a million is the daily nonstop service from Toronto to Tokyo . 4-digit numbers in the determination 1000-4999 commonly symbolize interior reach associate flights, at the same time as numbers larger than 5000 are oftentimes codeshare numbers for flights operated by ability of completely diverse airways. in america , air crashes are frequently said by ability of their flight huge type, at the same time as elsewhere they are frequently said by ability of the call of the region of the crash. what's usually said in the US as " Pan Am Flight 103 " is said elsewhere because the "Lockerbie catastrophe." both in the US and elsewhere, flight numbers will be taken out of use after a crash.
