Even with NCL being "firmer", it is still to NCL's advantage. For every person who calls after the price drop (CC users, likely 😄), think of how many people don't call. NCL doesn't "lose" anything from them. By giving FCC, NCL will get more money from the person who books another cruise. With NCL's artificially high prices, higher DSC, and reduced services, giving someone FCC isn't really "firm". NCL sees it as reeling in the fish.
