The web is full of fragmented info about special airline ticket deals, there are tens of blogs and forums that publish these offers.<p>I'd like to round up the most common places people check (forums, communities etc) into a public spreadsheet, so everyone can use them.<p>Let's leave the ticket search engines a side at the moment and focus on deals that are found by enthusiasts and published on the web.
Have had success in the past using Flightfox (<a href="http://www.flightfox.com" rel="nofollow">http://www.flightfox.com</a>) where you get a 'pro' to find you a cheap flight (for a fee). Have used it twice and both times they found a cheaper flight than I could with the difference being greater than the fee.<p>Most recently I travelled Melbourne to NYC and they found if I booked an unrelated flight between Manchester and London, the overall cost of the routes I was travelling was much lower, even when paying for an extra ticket I wasn't going to use (though I'm still not entirely sure why)<p>I also read recently about Skiplagged (<a href="https://skiplagged.com/" rel="nofollow">https://skiplagged.com/</a>) which finds flights from A - B - C which are cheaper than those simply A - B. If you are only travelling A - B this will be cheaper and you just don't hop on the flight from B - C. They're getting sued by United so obviously someone doesn't like what they're doing.<p>As for specifically deals, I use OzBargain (<a href="http://www.ozbargain.com.au" rel="nofollow">http://www.ozbargain.com.au</a>) though this is obviously Australian focused.
