I recently used Flightfox to book a flight from Monterrey, Mexico to London. The cheapest flight I found was US$1109, Flightfox found one for $959. It was well worth my $49 fee.
However, I'm puzzled as to how they found me this bargain price. The flight they found for me included third flight, which I didn't use (and indeed couldn't use), from San Jose, California to Reno, Nevada, on Alaskan airlines.... on a date I was in the UK.
The retail price on this trip was roughly $1300, and I got it for $959.
Somehow by bundling this flight with my round-trip fare from Mexico to the UK, I was able to save money.
How was Flightfox able to find this deal? How can I find them myself--assuming that's even possible, without some special agent mojo?
