At Pittsburgh International Airport (PIT), legacy carriers like American, Delta, and United offer convenient connections and loyalty benefits, while low-cost carriers such as Southwest, Spirit, and Frontier can provide the lowest headline economy fares. Legacy airlines include checked bags and seat selection on certain fare types, while budget carriers often charge for these extras — so compare total trip cost. Consider on-time performance, baggage fees, and route frequency when choosing the cheapest economy option for your itinerary.

Seasonal tips: In winter (January–February), take advantage of low demand for cheapest economy fares; in spring (March–April), avoid spring break weeks for better prices; summer (June–August) requires early booking to secure economy seats; autumn (September–November) often offers shoulder-season savings and the best chances for cheapest fares. Always account for weather-related delays in winter and peak-event surges in summer/fall, and pack light if traveling on deep-discount economy fares to avoid baggage fees.
