The best time to fly from Chicago O'Hare International Airport (ORD) to George Bush Intercontinental Airport (IAH) in May depends on priorities: for lower fares, target mid-week travel (Tuesday–Thursday) and early-morning flights; for reliability, choose morning departures to avoid afternoon thunderstorm delays in Houston.
