✈️ Flight Guide: Durham (RDU) → Houston (IAH)

May brings a mix of cultural events and holiday travel that can impact RDU→IAH passengers. In the Raleigh-Durham area, May typically includes university commencements, outdoor spring festivals and farmers markets across Raleigh, Durham and Chapel Hill. In Houston and surrounding areas, May features Cinco de Mayo celebrations, Memorial Day weekend events, outdoor concerts, and early-season Gulf beach activities in Galveston. These events drive peak travel days and demand for hotels and rental cars; include keywords like "Memorial Day flights RDU IAH" and "Houston May festivals" when searching. If traveling for a specific event, book flights and ground transport well in advance and check event schedules for exact dates.

The best time to fly from Raleigh-Durham International Airport (RDU) to George Bush Intercontinental Airport (IAH) in May is early morning on weekdays (Tues–Thurs) to avoid higher weekend demand and afternoon thunderstorms in Houston. For the best fares and seat availability, book flights 4–8 weeks ahead of travel and target departures mid-week. If you prefer lower crowds, consider flights immediately after Memorial Day rather than the holiday itself. Use long-tail keywords like "best time to fly RDU to Houston in May" and LSI terms such as "avoid Houston storms May" to optimize searches.

When choosing between direct and connecting flights from Raleigh-Durham International Airport (RDU) to George Bush Intercontinental Airport (IAH) in May, weigh the trade-offs: nonstop flights (often offered by United) minimize total travel time (~2h45m–3h) and reduce risk of missed connections during Houston’s spring storm season. Connecting flights via Charlotte (CLT), Atlanta (ATL), or other hubs may be cheaper or offer more schedule flexibility, but add layover time and increase disruption risk on busy Memorial Day travel days. Use search terms like "RDU to IAH nonstop vs connecting May" and consider fare differences, total door-to-door time, and airline reliability when booking. For business trips or tight itineraries in May, prioritize nonstop travel.

Major carriers serving the Raleigh-Durham International Airport (RDU) to George Bush Intercontinental Airport (IAH) corridor in May include United (frequent nonstop service), with American and Delta offering one-stop connections through their respective hubs (CLT, ATL). United’s advantages on this route include hub connectivity at IAH and frequent nonstop options; American can offer competitive prices via Charlotte connections, and Delta provides alternative schedules via Atlanta. When choosing an airline, compare total travel time, baggage policies, loyalty program benefits, and on-time performance for May, and use search phrases like "United nonstop RDU IAH May" or "best airline Raleigh to Houston May". For cost-conscious travelers, compare ancillary fees and look for bundled fares or basic economy vs main cabin trade-offs.
