MG007 - you said the allowance in SYD has gone down. Thanks for warning us all, now its up to us to write about it!
As I said before unfortunately nothing is going to get done by mentioning it here unless of course YOU wrote something down and sent it in to "management". If you did then well done, if not then you should have done!
To those that say you never get a reply, then keep writing until you do or send a copy to your Fleet Chief Pilot and ask him why you are not getting a reply. Get some backbone and write politely, stating facts and giving examples!
