Direct vs Connecting Flights — Choosing the Best Economy Option from STL

Connecting flights often provide cheaper economy fares, especially when routing through large hubs like Chicago O'Hare, Atlanta, or Dallas/Fort Worth.

For tight budgets, a longer connection can yield the CHEAPEST economy fare.
Extra Tips

- If minimizing cost, find one-stop itineraries via low-cost hubs or mix-and-match carriers carefully.
- Allow at least 90 minutes for domestic connections to reduce missed-connection risk.
