Pro Tips for Finding Cheap Flights to St. Louis
Finally, to wrap up, here’s a cheat sheet of pro tips that experienced travelers use to save on St. Louis flights:
Be Flexible With Your Dates: Flying on weekdays or during the off-season can lead to significant savings. Mid-week flights are often cheaper than weekend flights because fewer people want to travel then.
Set Up Price Alerts: Use RatePunk to set up price alerts for flights to St. Louis! You'll be notified when prices drop, ensuring you snag the best deal before anyone else. Don't miss out on potential savings!
Consider Nearby Airports: Check flights into airports near St. Louis, such as MidAmerica St. Louis Airport (BLV). Sometimes, flying into a smaller airport a bit further away can save you a bundle.
Book in Advance (But Not Too Early!): While last-minute deals are rare, booking too far in advance isn't always best. Aim to book 1-3 months before your travel date for domestic flights to hit that sweet spot.
Mix and Match Airlines: Don't be afraid to fly to St. Louis with one airline and return with another. Sometimes, booking separate one-way tickets with different airlines can be cheaper than a round-trip ticket.
Use Incognito Mode: Airlines and booking sites sometimes track your searches and raise prices accordingly. Use incognito mode or clear your browser's cookies to see the lowest possible fares – sneaky, but effective!
Look for Package Deals: Consider booking a flight and hotel package to St. Louis! Bundling your accommodations and airfare can sometimes unlock discounts compared to booking separately.
Follow Airlines on Social Media: Many airlines announce flash sales and special promotions on their social media channels. Follow your favorite airlines to stay in the loop and catch time-sensitive deals.
Check Budget Airlines: Budget airlines can sometimes offer significantly lower fares. Be sure to compare the total cost, including baggage fees and other extras, to ensure it's truly the cheapest option.
Redeem Rewards Points: If you have credit card rewards or frequent flyer miles, now's the time to use them! Redeeming points can significantly reduce the cost of your flight or even make it free!
By keeping these tips in mind, you’ll be well-equipped to find the cheapest flights to St. Louis and make the most of your travel budget. After all, the more you save on your flight, the more you can spend on a Broadway show, a nice meal, or an extra tour in St. Louis! 🎉✈️
