Which airline can fly direct from Bangkok to Seattle?
The following airlines operate direct flights on the route Bangkok — Seattle:
Seattle–Tacoma International Airport (SEA) serves as the principal international gateway for the Seattle metro area and typically functions as a major hub for both full-service carriers and regional airlines, with strong presence from Alaska Airlines and Delta. Fares can range from budget-competitive to premium depending on carrier and time of year. SEA lies about 13 miles (20–25 minutes by car without heavy traffic) south of downtown Seattle; options to reach the city include Link light rail (roughly 35–40 minutes, low to moderate fares), shuttle vans and ride-hailing (25–45 minutes, fares vary), or taxis (similar drive times, higher cost). Pros: modern terminals, plentiful flight options and good public-transit connectivity; cons: can be busy during peak hours and road congestion may extend travel times.
Bangkok is served primarily by Suvarnabhumi (BKK) and Don Mueang (DMK). Suvarnabhumi, the main international hub, typically handles full-service carriers and long-haul flights and can be pricier to reach from the city center. It sits about 30–35 km east of central Bangkok; by Airport Rail Link plus BTS/metro it usually takes 35–60 minutes with fares generally in the low single digits to around $2–5, while taxis can take 30–60 minutes depending on traffic and cost more. Pros: modern facilities, wide airline choice and direct long-haul connections. Cons: busy peak periods and sometimes longer transfer times across the complex.
Don Mueang mainly serves low-cost and regional carriers, often preferred for domestic and short-haul international routes and sometimes cheaper fares. Located roughly 20–25 km north of downtown, journey times can be 30–60 minutes by taxi depending on congestion; public buses and commuter trains are available at lower cost but can be slower and less frequent. Pros: smaller terminals and quicker check-in for budget flyers; cons: fewer amenities than the main hub and potentially limited late-night connections. Travelers usually weigh convenience of terminals versus airline and fare when choosing between the two airports.
Fly nonstop from Bangkok to Seattle for the quickest, most convenient way to cross the Pacific — fewer hassles, no long layovers, and more time to enjoy your trip. While connecting flights can sometimes be cheaper, a direct service saves hours and offers a more comfortable, straightforward journey between these vibrant cities.
