Firstly never understood some airlines obsession with twin time:
what difference is there between a seneca and a cherokee normally ?not much.
the only twin time that counts is when an engine quits and then you need to be sharp to stay alive.

Luke, don't get frustrated I had ppl students that got jet jobs quicker than me.That's life: take alook at something like'pop idol' how many times has the better singer lost out ? now thats a cutthroat industry !!

Use your contacts, a recommendation from a mate in the relevant airline is worth so much, because he or she is putting their ass on the line. the old boys network still exists in some places: but then I am sure when you get your airline job you will recommend your friends and there is nothing wrong with that.

Don't get bitter it will ahppen sooner or later,
all the best.
