If you don't get a reply try again, make it clear that Dragonair is your No1 choice. I think they only look at the top few applications until they have enough candidates for the next interview date and then bin the rest to keep the office tidy.
If you have a mate there then get him to go see Ann or Doris and drag your CV to the top.
Scottie the rumour is true! Routes are MAN,AMS,DXB,HKG. Also PVG,XMN,TPE,KIX from HKG.
