Travel Tools - Travel tool that gives alerts for fare drops below certain #?

A few years ago there was a site that sent me email alerts when the fares between A and B dropped below a certain (pre-set, by me) amount. I could design unlimited "trips" and entered a dollar amount X, and then set the filters to notiify me when X-50 happened, or X-75, etc.

I'm thinking it was Airfare WatchDog or (maybe FareCompare??) but whatever, I'm missing it.

Is there another site that does this? Even one that has subscription fee? I'm willing to pay.

In Australia, Webjet has it.

I've tried Yapta ,*****dog,and priceline,but none of them really helps.
To locate real good airfares,you still have to search by yourself.

Belfordrocks, I did see a similar critter on the Webjet.com.au site.

I'm looking for a feature that is even more in-depth and allows you, the reader, to choose whatever point A and whatever point B you want. Even the most obscure segments, not just popular hub routes.

There was one about 3 years ago here in the US. I had pages of trip combinations lined lined up (subsequently received massive alerts every day) but it took a lot of the work out of looking through the matrix.

I thought yapta was supposed to do this? I had signed up for it years ago but haven't used it in a while so I don't remember exactly.

kayak.com has the fare alert like how you described it, but I am not sure how it will work if you are not in the US.

Kayak does it. Search for the trip you want, then click "price alert" on the left hand toolbar.

Kayak's alert system isn't it.

This is what I'm talking about:

MIA to JAX / current lowest fare $210 / alert me when price drops > $50
MIA to CLT/ current lowest fare $384 / alert me when price drops > $30
JAX to CLT / current lowest fare $257 / alert me when price drops > $25
CLT to IAD / current lowest fare $189 / alert me when price drops > $30
MIA to IAD / current lowest fare $212 / alert me when price drops > $20

The first column are my selections, all with sample dates. The second column is what the program spits out. The third column--from "drops [or increases] and > [or < ] and the dollar amount--are all fields that I have selected.

I had hundreds of these selected. As you can see, it came in very handy when I wanted to piece a trip together via segments. I swear it was WatchDog, but then again, I might be wrong....

--Seems like Expedia has it now: http://www.expedia.com/daily/highlights/fare_alert/faq.asp

Does Orbitz still have fare alerts? The link above redirects to the site map. The site map does have a fare alerts link, but that connects to a Travel Deals page that has no mention of fare alerts .....
