The airport's most vital routes are flights to key domestic hubs, including Atlanta (ATL), Charlotte (CLT), Dallas/Fort Worth (DFW), Chicago (ORD), and Denver (DEN). It also offers direct flights to many popular business and leisure cities like Orlando (MCO), Las Vegas (LAS), Phoenix (PHX), Los Angeles (LAX), and New York (LGA, JFK). International service includes direct flights to London (LHR), Paris (CDG), Cancún (CUN), and seasonal services to the Caribbean.

Raleigh-Durham is a focus city for Delta Air Lines and American Airlines. It is also served by United Airlines, Southwest Airlines, and low-cost carriers Frontier and Allegiant. International carriers like British Airways and Air France operate from RDU. This mix creates a competitive environment.

To find affordable flights from Raleigh, book domestic flights 3-6 weeks in advance. For leisure destinations on Southwest, Frontier, or Allegiant, book 2-3 months ahead for the best deals. Use flight comparison tools and set price alerts. Flying on weekdays (Tuesday-Thursday) is typically cheaper. RDU often has competitive fares to Florida, the West Coast, and major hubs. For international travel, connecting through Atlanta (ATL) or Charlotte (CLT) is standard, but direct options to Europe are available. Southwest's presence often provides good value with transparent pricing.
