Flights Review

Feb 28, 2020

The only thing that I didn’t like was when one of the pilots came around showing a brochure for the United Airlines credit card. Seemed a little bit tacky.

Feb 24, 2020

Overall my experience was good. The only down fall was they sent our luggage to NC on the way home vs. Denver. So we will not get it for over 24 hours. Which is a bit of a bummer.

Feb 20, 2020

I am generally happy with the flight, but I miss the customer service atmosphere that used to be the norm in the airline industry of a few years ago when beverages, snacks (even meals), and a complimentary carry on and checked bag were free of charge (or at least not treated as extras for a price). That level of service demonstrates value for the customer and encourages repeat travel, even company loyalty. Please consider bringing this back in the context of your business.

great crew who were welcoming and helpful

Jan 7, 2020

The price is pretty cheap and that is fantastic, but honestly other than the friendly staff, flying frontier has little else to offer to make the flight a positive experience.

The flight attendant bought me a rum and coke because I think I looked haggard.

Flights from Washington DC to Denver

The Best DC Airports

Before you call airlines looking for flights from Washington, DC, you should check with Orbitz.com. The two major airports in DC are Washington Dulles International Airport and Ronald Reagan Washington National Airport. Alaska Airlines, US Airways, and Frontier Airlines handle domestic flights from Ronald Reagan, while Virgin America, ExpressJet Airlines, and Colgan Air operate out of Washington Dulles. Ronald Reagan is only three miles from the downtown area, and Washington Dulles is 26 miles from downtown.

Long-Term Parking Options

The five parking lots at Ronald Reagan offer daily and hourly parking rates, and the airport charges $20 per day for parking in the long-term lots. The economy lot only charges $12 per day, but this lot is open and uncovered. Washington Dulles has two long-term parking lots that charge $17 per day and one economy lot that charges $10 per day. For $30, you can use valet parking.

Public Transportation Choices

The Metrorail and Metrobus make at least one stop at each airport every day. The stops are clearly marked around the city, and you can find maps that help you find the correct line. Taxis are not as low cost as the public transportation options because the drivers charge a pickup fee, baggage fee, fee per mile, and a fee for any time that the driver must wait.

Places to Eat

Both airports offer a range of dining options. Washington Dulles is home to Dulles to Go, Five Guys, Subway, and Wendy's, while Ronald Reagan has Dunkin' Donuts, Euro Cafe, and Jerry's Subs & Pizza. Once you have something to eat, you can browse through the sales at some of the shops surrounding the restaurants. If you want to enjoy your vacation, use Orbitz.com to look for flights from Washington DC.

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.
