How BOS–MEX 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 MEX 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 progressive booking buckets, with early‑bird low‑fare buckets filling first on the feeder leg and higher‑priced buckets opening later for the long‑haul segment.
- Nearby airports: departing from LGA (New York LaGuardia), JFK (New York John F. Kennedy) can change the fare.
