Hi all new to aff and it's a very informative site. Can someone tell me what is classed as a flight sector. Eg you have to fly 4 sectors in one year and reach 700 sc to reach sg. I'm flying Mel via sin lhr and then on to vie and return . Is Mel to sin 1 sector or Mel to lhr 1 sector even tho it's all one flight number being qf9. Thanks for your help in advance:-|
