How BOS–FCO gets cheaper
- Regional point-of-sale pricing: the same flight is often filed at different tariffs in different countries and currencies. How it works.
- Split-hub routing: pricing BOS to a competitive hub and that hub to FCO as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Revenue management releases inventory in a sequence of fare buckets, starting with highly discounted seats that fill quickly, then progressively higher‑priced buckets as demand on the BOS‑FCO corridor rises.
- Nearby airports: departing from LGA (New York LaGuardia), JFK (New York John F. Kennedy), or arriving at CIA (Rome Ciampino), can change the fare.
