Agreed, based on what we think we know at this stage there is no compelling feature unless it is buried in the VISA Infinite bundle.
Compelling features (for me) which I believe are buried in the Visa Infinite bundle:
GogoŽ Inflight Wi-Fi
During your next trip, enjoy complimentary Internet access with Gogo Inflight Wi-Fi service on up to 12 flight segments per year on any Gogo equipped aircraft. To access the Gogo Inflight Wi-Fi benefit, register your Crystal Visa Infinite Card in the Benefits Portal at myvisainfinite.com/cnb.
Visa Infinite Discount Air Benefit
Save $100 on air travel when you use your Crystal Visa Infinite Credit Card to book a qualifying U.S. domestic round-trip coach airline itinerary for 2 to 5 travelers through the Visa Infinite Discount Air Benefit website.
Unfortunately, I'm no longer domestic so I will have very limited use of the domestic tickets except on my visits home but since I fly as a family of four, that's might not be too bad depending on how that airline benefit works. Gogo will be similarly limited but as long as its a $300 AF credit, and PP Select with guesting, I might be willing to hold onto this one for my wife and cancel her AU on my Prestige for a net $100 (AF credit and $50 Prestige AU). The only reason I have her as an AU for the Prestige is so she can have her own PP Select for herself and the kids when we fly separately anyway.
