Tulsa International Airport

Tulsa International Airport is the second-largest commercial airport in Oklahoma after Oklahoma City's Will Rogers (OKC), serving the Tulsa metropolitan area's roughly 1M residents and drawing catchment from northeastern Oklahoma, southeastern Kansas, southwestern Missouri, and northwestern Arkansas. Located 5 mi (8 km) northeast of downtown Tulsa at 677 ft (206 m) elevation, TUL handles 90 routes across 59 destinations through 25 airlines. The airport sits on a historically significant site — Tulsa was briefly the "Oil Capital of the World" during the 1920s petroleum boom, and the airport's roots trace to that era's private-aviation infrastructure supporting the oilfield services industry. No airline operates TUL as a hub, but Southwest holds the largest share of departures and uses the airport as a focus city for Oklahoma connectivity. American, Delta, United, Allegiant, Frontier, Spirit, Breeze, and Sun Country round out scheduled service. Route emphasis falls on major central and southern U.S. hubs — Dallas–Fort Worth, Atlanta, Houston, Chicago–O'Hare, Denver, Charlotte, Phoenix, Las Vegas, Minneapolis, Detroit, Washington–Reagan — with significant leisure service to Florida (Orlando, Tampa, Fort Lauderdale), Mexico (Cancún, Puerto Vallarta), and the Caribbean. The airport handles minimal scheduled international service but supports substantial general and business aviation activity given Tulsa's historical oil industry wealth and ongoing presence of major employers including Williams Companies, ONEOK, and American Airlines' massive Tulsa Maintenance Base — the world's largest airline maintenance facility, employing roughly 5,000 workers performing heavy checks on American's mainline fleet. The airfield has three paved runways — 18L/36R at 10,000 ft (3,048 m) in concrete as the primary, 08/26 at 7,376 ft (2,249 m) in concrete as crosswind, and 18R/36L at 6,101 ft (1,860 m) in asphalt — providing significant redundancy and capacity exceeding the passenger traffic levels. A single unified terminal handles all commercial traffic, organized around two concourses (East and West) and connected by a central ticketing/check-in hall. The presence of the AA maintenance base gives TUL unusually heavy widebody activity for a mid-sized U.S. airport, with 777, 787, and A321 aircraft routinely positioned for heavy maintenance movements.
