Connecting itineraries often lower the fare substantially, especially when routed through competitive hubs like Charlotte (CLT), Atlanta (ATL), or Newark (EWR).

United (hub carrier at IAD): Strong route network and frequent nonstop options; basic economy often excludes seat selection and checked bags but loyalty benefits can offset costs. American: Competitive transcontinental and domestic economy fares with periodic sales; baggage policies similar to legacy carriers. Southwest: Popular for budget domestic travel with two free checked bags (often cheaper overall despite slightly higher base fares). JetBlue: More legroom in standard economy and free Wi-Fi on many aircraft, but sales determine relative cheapness.
