Flights to Denver

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.

Denver Airport Information

Many of the major domestic and international carriers offer relatively cheap flights to Denver International Airport, the primary airport serving the greater Denver area. The airport is roughly 28 miles east of downtown Denver and a little over an hour from the closest major ski resort. Whether you're coming into town on business or for a ski vacation, be sure to use Orbitz.com to reserve your flights and hotel.

Ground Transportation in Denver

The RTD bus is the primary means of public transportation in and around Denver, so most visitors use a private car service, share-a-ride shuttle or taxi to get into town. Many of the large hotels also offer free shuttle service to and from the Denver airport, and there are chartered shuttles and buses to take you to the outlying ski resorts. A cab from the airport to the downtown area will cost you between $60 and $70, so you might be better off using Orbitz.com to add a rental car to your low-fare ticket purchase.

Denver Area Weather Information

The summer months are mild in Denver, with average temperatures ranging from the low 60s to the mid-80s. The average winter temperatures in Denver range from the teens to the low 40s, and you can expect anywhere from 22 to 61 inches of snow each season. Layer your clothes in the summer to accommodate mild and warm temperatures, but be sure to bundle up in the winter.

What to Do in Denver

Although the city has its share of high-end eateries, historic landmarks, museums and shopping venues, the Denver lifestyle is all about the great outdoors. Denver has more than 4,000 acres of traditional parks and 14,000 acres of mountain parks to keep outdoor enthusiasts engaged. Enjoy your stay, and don't forget to use Orbitz.com to find cheap flights to Denver for your next Colorado vacation.
