I just found out that if you perform an airline code and flight number search on Google in the format "AA 250," for example, it returns at the top of the search list, two hotlinks:

1) goes directly to the Travelocity FLIFO page for the flight in question; and

2) goes directly to the FLIFO page for the flight in question at fboweb.com.

Pretty slick, and much easier than going through any of the websites themselves; FLIFO is two clicks away!
