Major Houston events like the Houston Livestock Show & Rodeo (typically March) and energy conferences raise demand and push economy fares up at George Bush Intercontinental Airport (IAH). For the best economy prices around high-demand events, book early or choose flexible nearby dates. Consider flying into nearby airports such as Houston Hobby (HOU) or even Dallas/Fort Worth (DFW) and taking ground transport if prices spike.

Arriving at Houston (IAH) FAQs
Cheapest Economy Fare (ECO) refers to the lowest-priced economy-class tickets that prioritize basic seating and minimal extras. These fares usually include only a personal item and impose stricter change/cancellation rules.

Consider multi-airport searches to find lower-cost arrival options and compare ground transport costs to ensure overall savings.
In October, demand typically decreases after summer and before fall holidays, which often lowers cheapest economy fares for arrivals.
