Chase Sapphire Reserve: dynamic Points Boost pricing, typically 1.5-2.0 cpp on select bookings (not a fixed floor). Verify actual portal price for the specific booking. If cash price is $900, portal cost = 60,000 UR points. If award price is 88,000 United miles, cash via portal is better value.
Amex: typically 1 cpp via portal (worse value, use transfers instead).
Capital One Venture X: 1 cpp via portal, but transfer partners can be better.
