I am looking for tix to rome and travelnation comes up with tix about $200 a piece cheaper for our trip. It just isn't a website I am familiar with.
I've never used them but as long as they give you a record locator number you should be able to verify from the airline's website that you actually have the ticketed reservation. Be sure to use a credit card and don't pay the bill until are sure you have a confirmed and ticketed reservation. While you are at it you can probably also confirm and, if you wish, change your seat assignments.
