It may be that UA is actually running an FAE-LON search and then filtering out the other airports or something. If you'd like to post a sample date, somebody can take a look and see if they can reproduce the same issue, but I think you're probably just running into "the computer returns what it returns."
So true on the logic comment.
vip66, are you searching for round-trip or one-way? The limit on search results is exacerbated by round-trip searches. The return leg tends to show very few options. I've had the opposite problem with agents where a routing shows available in a one-way search, but they seem to have to search through a much larger set of routings and sometimes can't see the one I can see on the website. As noted, the multi-city search isn't very helpful due to the married segment inventory that UA is using.
