The NRT-BOS flight is around $355.
Add those together and you get more than the total, which is a bit confusing, but I think it's clear we need to decide how much we want to stop in Madrid...
But Matrix doesn't price RTW fares. I understand how fuel surcharges are typically added on normal fares (they're auto-priced from the fare rules, where the surcharges are explicit). But for RTW fares, I don't know how they are determined. They're not in the fare rules.
