I'm hoping I can pose this question in such a way that it will be objective enough to be answerable.
When I'm preparing for a trip, I generally start watching air fare prices well in advance, and check multiple search engines. I also try to construct my own creative itineraries, using one-way flights, hidden-city-ticketing, two sets of one-way flights which link up in a common city, etc.
The one trick I've never tried (and probably won't) is fuel dumping (as mentioned in another post of mine.
Some online blog posts suggest that Flight Fox will basically do the same thing I do. I don't want to pay $49 to be told I already found the cheapest price.
The one time I did use Flight Fox, I was given a cheaper price than I could find on my own, but it was the result of fuel dumping, and I'm not excited about paying someone to help me do fuel-dumping, as I'm undecided about the ethics of this practice.
Assuming I'm only interested in taking ethical flights, and I do my own leg work before hand, will Flight Fox likely benefit me?
