Spongebue is correct. Buddy pass prices run about $98 for RT for that distance. Same for SFO/SLC or CVG/ATL or MCO/CVG, CVG/NY (any)
MEM would be same. I'd be surprised if you can get a fare in that range except on a special or Low Cost Carrier like Spirit?
Int travel is def worth buddy pass IF you're flexible and willing to change destination/dates last minute but pass ticket overseas can be $4-5-600+ (with a shot at business class as the dangling carrot)
The key is flexibility--always and in all ways! (anxiety is the "bonus" that might come with pass travel, too)
