The Birdie - Theoritically its on ''Telescopic milleage principle''. Practically - its just another cuthroat competition between the airlines which decides.

There is a IATA ( International Air Transports Association) published fare for each and every points operated.You will be shocked if you loook at them. All these fares we see now are Market Fares ( under cut fares much lower than the IATA actual fares).

The market fares are effected by several factors, competition, demand and supply..etc etc
