Traveling from Seattle to Hanoi

Seattle Airport

While Seattle is home to several airports, the only one that handles commercial flights is the Seattle-Tacoma International Airport. Also known as Sea-Tac, this airport is responsible for all incoming flights, along with flights from Seattle. Alaska Airlines, Air Canada, Delta Air Lines, Southwest Airlines, and US Airways are a few airlines that operate out of this airport. Located in SeaTac, Washington, the airport sits along the intersection of three state routes: 99, 518, and 509. Though the airport has three terminals, only the Concourse Terminal and North Satellite Terminal handle domestic flights. The South Satellite Terminal specializes in international flights. It's just a short drive from the airport to downtown.

Transportation

When you need to reach your hotel quickly, head for the public transportation system, which consists of Sound Transit and Metro Transit. The buses and light rails only cost a few dollars, and you can visit the sales counter at any station to purchase tickets for your trip. The light rail system drops passengers directly at some of the top hotels in the downtown area. Seattle uses a grid system for its roads, which makes finding your hotel easy if you drive. You can use the Orbitz.com sign to look for rental cars from the airport.

Weather

If you visit during the spring, winter, or fall, you need a warm coat and an umbrella. Though the city does not get snow, it does get a high amount of rain during these seasons, and temperatures that can drop below 40 degrees Fahrenheit. The summer is much warmer, with temperatures in the high 70s and less rainfall.

Popular Attractions

Seattle is home to dozens of cultural activities and attractions, including the Seattle International Film Festival, the Henry Art Galley, the Woodland Park Zoo, and the Seattle Underground Tour, which takes you through older parts of the city. When you look for flights from Seattle on Orbitz.com, take a few minutes to look for other low-cost attractions in the city.

Noi Bai International Airport

The Noi Bai International Airport is one of the largest airports in Vietnam, and it is the primary destination for travelers to this area. Uni Air, Vietnam Airlines, Qatar Airways, and several other major airlines offer flights to Hanoi. The airport sits just 28 miles from downtown Hanoi, and depending on traffic, you should reach downtown in 45 minutes or less. Finding tickets that fit into your budget is sometimes rough, but Orbitz.com makes the process easier by offering hundreds of deals on flights every day.

Different Taxi Types

Taxis offer the best mode of transportation for travelers, because the streets are small and crowded, and visitors might not know how to get around Hanoi. Taxis are available in several different types: bicycle taxis, motorcycle taxis, and traditional taxicabs. Bicycle and motorcycle taxis work best for one or two people, while taxicabs have room for multiple passengers.

Weather in Hanoi

A vacation planner or guidebook will sometimes skip over the weather, but it can make your trip easier or harder. Summer temperatures in Hanoi can hit 30°C (86°F) or higher, while winter temperatures average in the high teens (low 60s in Fahrenheit).

Hanoi Tourist Attractions

A trip to Hanoi isn't complete without a visit to some of the top tourist attractions. The Old Quarter and Fine Arts Museum teach you about the city's history, while the Lake of the Restored Sword offers activities suitable for children. When you need to plan your Hanoi vacation quickly, visit Orbitz.com. With low prices on attractions, hotels, and flights to Hanoi, you can purchase everything you need without emptying your bank account.
