Definitely not a gimmick. Some great deals can be found. I have personally saved anywhere from $30-100 R/T on certain routes. Usually, you'll have a few hours from the time that fares are released to book and then that particular DING expires and new ones arrive with new city pairs and fares soon thereafter. However, with the busy summer season upon us, the really low fares such as $29-39 one-way may be a little scarce. But overall, give it a shot and check for updates as often as you can. You'll find something you like.
