List price (for minimum monthly spend) is in the 10s of thousands, but of course everyone does deals to reduce fees at this level. The problem is that those data feeds don't hold the key to the best flights. We're trying to leverage the stuff that won't be in data feeds for at least a decade (likely forever).
