While I don't think this particular offer will be rolled out to
the entire Membership Rewards program due to the tremendous opportunity to lose money on high - value premium fares, I think some version of the experiment may eventually make it to the rest of us.
Though the Citi Prestige card also offers a Priority Pass
membership to authorized users for a lower $ 50 fee (plus you can bring along your
entire immediate family for free), Citi Prestige can't compare to the Sapphire Reserve card's
rewards program and flexible annual travel credit.
