Seattle–Tacoma International Airport (SEA), often called SeaTac, is the region’s primary international and domestic hub, serving legacy carriers like Alaska Airlines and Delta alongside several international and low-cost operators. Fares can range from budget-friendly to premium depending on carrier and timing. The airport sits about 14 miles south of downtown Seattle; travel options include the Link light rail (roughly 30–40 minutes, moderate fare), airport shuttles and shared vans (30–50 minutes, variable pricing), taxis or rideshares (25–45 minutes, fare depends on traffic and surge), and rental cars. Pros: extensive flight choices and frequent connections; cons: can be busy at peak times and requires a bit of travel into the city.
Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the international hub and main long-haul gateway, typically handling premium carriers and full-service airlines; it sits about 30–40 km east of downtown and is usually reached by the Airport Rail Link (25–35 minutes), taxis (30–60 minutes depending on traffic) or shuttle buses. Don Mueang (DMK) is nearer the city (about 20–25 km north) and often functions as the low-cost and regional airport for budget airlines; travel times by taxi are commonly 25–50 minutes and shuttle buses or rideshares provide alternatives. Fares can vary widely with taxis or rideshares often costing a moderate amount and the rail link offering the lowest predictable cost. Pros: Suvarnabhumi tends to be more modern and comfortable for long-haul connections, while Don Mueang can be quicker for budget travelers. Cons: Both can be affected by Bangkok traffic, and transfers between airports typically take an hour or more, so allow extra time for connections.
