Dallas is served primarily by Dallas/Fort Worth International (DFW) and Dallas Love Field (DAL). DFW functions as a major international hub with extensive long-haul and domestic connections, typically hosting legacy carriers and global alliances; fares can be competitive for transcontinental and international routes. Located roughly 20–25 miles northwest of downtown Dallas, travel options include DART trains, express shuttles, rideshares and taxis — expect 30–50 minutes to the city center depending on traffic, with fares varying widely by mode. Pros: extensive flight choices and amenities; Cons: large layout can mean longer connection walks and transfers. Dallas Love Field (DAL) sits much closer to central Dallas — about 6–8 miles north — and often operates as a more compact, budget- and point-to-point oriented airport, typically used by low-cost and some legacy carriers for domestic services. Ground transport options include DART buses and light rail connections, rideshare and taxis, with city center journeys usually taking 20–30 minutes and modest fares relative to longer express options. Pros: convenient proximity and simpler navigation; Cons: fewer international flights and limited long-haul connectivity compared with DFW.

Seattle–Tacoma International Airport (SEA) is the primary international gateway for the Seattle metro area and functions as a major hub for both full-service and low-cost carriers, including Alaska Airlines and Delta.

SEA typically offers a broad mix of routes and competitive prices, with strong amenities but occasional congestion at peak times. Pros: extensive connections and services; Cons: distance from central Seattle and possible delays during busy periods.
