How SEA–CDG 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 SEA to a competitive hub and that hub to CDG 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 early‑booking buckets at discounted levels, then progressively restricts inventory as the departure date approaches, with the split‑hub legs each following their own bucket cadence.
- Nearby airports: check alternate departure airports, or arriving at ORY (Paris Orly), can change the fare.
