I figured it would be cool if I stickied a post like they do on other sites, and we can all add our personal bookmarks for cheap travel since so many of us love traveling....
If you're flying American Airlines, I highly recommend checking out this thread, where you can almost immediately get 5% by buying an Entertainment book.

Cheapoair, seems to be one of the better airline consolidators. I'm adding this one because it's managing bookings I'm not finding elsewhere. It just came up with RDU to BRU for $650, while every other site is showing about $1000. Sure it involves transversing New York and three airlines... but it's cheap.

ITA Software is like Orbitz, & all the commercial cheap sites without all the B.S.

I like Cheap Flight's travel matrix, reminds me of the original "bestfares.com" site.

Air Fare Watchdog has mainly domestic airfares, but sometimes good deals

Rental Cars Discounts:
Enterprise:
This method is questionable, but offers deniable plausibility of accidentally clicking on a corporate account and gaining their discounted rate. Various choices will show up, but you have to hunt for the best discount, but by doing so It can often provide up to a 25-75% discount on car rentals:
Enterprise discount
Avis:
A similar method to the above Enterprise, but with Avis car rental is available here:
Avis AWD Discounts
We've also been told the following on Avis:
Hello , D454000 = the BEST AVIS code , have used it for years and it saves me anywhere from 1/3 off to half off, really... even when I call it in, the operator jumps back and says "Whow, great code, where'd ya get it?" It was in a little promo letter they sent out yrs ago.....
