Low pay and long airlines....that is just about most airlines...but not compared to LHR base within cx. Like you i wanted to get into cx LHR for the same reason...but thats another story. I'm happy where I am at the moment, it will be a great experience and a passport to other airlines should i choose to move on....anyways....I would send another application, the full version, and if possible tell them to cancel the other one, giving explanation. At the same time contact via telephone/email and explain the situation.
