It is not in their interest to hire someone who has 'popped over' to the US and flown crap monotonous unsupervised sorties back and fore just to stack up hours. You'd have absolutely no credibility.
Thomas coupling,
Thats funny, I did exactly that and am now a Captain for a large legacy carrier in the UK. You are talking rubbish mate.
In fact, those hours over in the USA were some of the most enjoyable times in my life.
