The best time to fly from St. Louis Lambert International Airport (STL) for cheapest economy fares (ECO) is typically during shoulder seasons — late January to early March and September to early November — and midweek departures (Tuesday–Thursday). For domestic leisure travel, booking 3–8 weeks in advance often yields the best economy prices, while international low-season windows require 2–4 months of lead time. For last-minute trips, monitor flash sales and consider red-eye flights, which are more likely to feature remaining ECO inventory.

Choosing between direct and connecting flights from St. Louis Lambert International Airport (STL) depends on priorities: direct flights cost more but reduce risk of missed connections and luggage delays, while connecting itineraries often unlock cheaper ECO fares by routing through hubs like Chicago (ORD), Atlanta (ATL), or Dallas/Fort Worth (DFW). For budget travelers focused on price, a single connection with a 90–150 minute layover usually offers the best balance of savings and safety. However, if time or reliability is the priority, book nonstop flights if available and within budget.
