I, too, tried Travelocity after a recommendation from a friend. I thought it was cool until I tried TheTrip.COM reservation service. With it, can get up to 15 sample fares each way from all available airlines on that route. Pick the one I like or investigate a particular airline's incredibly low fare by selecting to view that airline only (or combination of airlines) for all their fares or flights on a given day.

When I tried Travelocity it only gave me three fares, so I've been using the TheTrip.COM since for fare review on a route I may take.
