Johnny just found a great deal on twitter - Houston to Athens round trip for $855 posted by @airfarewatchdog.
Johnny also recommends looking at Flightcaster.com. It's a great site that can accurately predict if your plane will be on time, late, or cancelled.
Johnny also says that spending a little extra time and doing some searching to see if you can get a better deal. He has a great booking tool at JohnnyJet.com that can help you find a great deal.
Also, this Memorial Day, why not give your upgrades to a soldier?
