I am starting to dive into the fun world of FDs. And I have been playing around with fares from the city of angles to sushi. Base fare on the R/T on an airline in bankruptcy is $176 and and $194. YQ is $592. I manage to find a 3X that reduces YQ to $287. The 3X is for a flight from Vodka to Pilsner, unfortunately the base fare is $234, so not much of an overall savings. But it is still fun to see it work. Update: Sweet, Looks like I got it to go about as low as I can get. R/T to sushi is $824 a/i. That is a savings of about $225. Not great but a good first effort. Now if only I knew the reasoning for why the FD worked as opposed to trial and error/dumb luck. Base fare on the 3X was $78 and YQ dropped to $287.
