I know what you mean that some of the contacts are vague, but others are more solid. Given that you graduated summer '02 it would be understandable that you Oxford didn't have too many contacts given the state of the airline industry at that time. Things do now seem to be picking up.
I have had two interviews and I have gained employment with Oxfords help. You have to remeber that when airlines approach Oxford to see if they can provide pilots, they may have their own requirements and one of which may well be age. It seems that if they are going to take low hour pilots, they like them to be fairly young.
