I subscribe to tripadviser.co.uk, cheapflights.co.uk and netflights.com (as well as all the airlines) e-mail bulletins. Sometimes you can tailor these to send you alerts when there are promo's from your local airport to your preferred destination. I've managed to get a few bargain deals like this. The downside is that you do get lots of unwanted e-mails, but worth it if you can save yourself a few hundred quid
