How ORD–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 ORD 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: Airlines release inventory in fare buckets that start with high‑yield seats and gradually open lower‑priced buckets as demand softens, allowing the split‑hub legs to enter a cheaper bucket sooner than the nonstop.
- Nearby airports: departing from MDW (Chicago Midway) can change the fare.
