Somewhere over the Canadian Rockies, the window shade goes up and the mountains below start to look a lot like the ones you left behind in Colorado, only emptier and whiter. That is the moment many travelers realize Anchorage is a direct flight from Denver in summer. The route is a nonstop one, it lands at an airport close to downtown, and the main thing to have in your wallet is the right ID.

Which airlines fly from Denver to Anchorage?
Denver is on the list of cities with nonstop flights to Anchorage in summer, so you can leave the Front Range in the morning and be in Southcentral Alaska without a connection in Seattle or Salt Lake City. The same list includes Atlanta, Chicago O’Hare, Dallas-Fort Worth, Houston, Los Angeles, Minneapolis, Newark, Phoenix, Portland, Salt Lake City, San Francisco and Seattle/Tacoma, which tells you how many of the country’s big hubs reach Anchorage without a stop.
The airline roster at Ted Stevens Anchorage International Airport includes Alaska Airlines, American Airlines, Delta Air Lines and United Airlines, along with Air Canada, Sun Country Airlines and a few seasonal carriers. All of those serve the South Terminal, the domestic one. Which of them runs the Denver route in a given season is something to confirm when you search fares, since the nonstop list is described for summer.
Alaska Airlines and its Anchorage hub
Alaska Airlines is headquartered in SeaTac, Washington, and its primary hub is Seattle–Tacoma International Airport. Anchorage is one of its other hubs, alongside Los Angeles, Portland, San Diego and San Francisco. That matters if your plans include a connection, because the airline’s network is built around the West Coast, Alaska and Hawaii.
The carrier has deep roots in the city. It began life in 1932 as McGee Airways, whose first service ran between Anchorage and Bristol Bay, and in the 1940s its headquarters stood in Anchorage. It is also a member of the Oneworld alliance, and its frequent-flyer program is called Atmos Rewards, which is useful to know if you collect miles with a partner airline.
American, Delta and United
American, Delta and United all appear among the South Terminal airlines, so a Denver traveler who prefers a particular loyalty program has more than one place to look. United is the carrier most Denver travelers think of first, since the city is one of its big hubs, but the airport’s own list simply names the three together without saying who flies which route.
If you are comparing, search by date and let the results show you which airline is operating the nonstop on your day. A nonstop is listed for summer, and the best time to visit Anchorage runs from May to early September, so those months line up well with the service.
How busy the airport is
More than 240 flights arrive daily at the Anchorage airport, which is a lot for a city of its size. Part of the reason is cargo: FedEx Express, Atlas Air, Polar Air Cargo and UPS Airlines all use Anchorage as a hub, and FedEx alone can handle as many as 13,400 packages per hour. Passenger flights share the runways with that freight traffic.
Next to the airport sits Lake Hood Seaplane Base, described as the busiest seaplane base in the world. From the terminal area you may see small floatplanes lifting off, a first hint of how much of Alaska is reached by air rather than road.
Where do you land?
You land at Ted Stevens Anchorage International Airport, known by its code ANC, which sits 5 miles southwest of downtown Anchorage. Its address is 5000 W. International Airport Rd. Nothing about arriving here requires a long transfer to reach the city, and that is a relief after a flight from Colorado.
South Terminal and North Terminal
The airport has two terminals. The South Terminal handles domestic flights and has 24 gates, and it serves Alaska Airlines, American, Delta, United, Air Canada, Sun Country, Condor departures and Discover Airlines departures. A flight from Denver belongs here.
The North Terminal, with 8 gates, is the international one. It receives Condor arrivals, all international seasonal charter flights and military flights. Unless you are on one of those, you will not need it, though you may notice the signs for it when you step out.
Getting from the airport to downtown
Anchorage People Mover bus Route 40 serves both the North and South terminals and connects to the downtown Transit Center. It comes every 15 minutes on weekdays and every 30 minutes in the evenings and on weekends, so a late arrival on a Saturday still has a bus, only a less frequent one.
Downtown is the short hop of 5 miles from the terminal, which puts you near the Alaska Railroad Depot at 411 West 1st Ave. If your trip continues by train, the depot can be reached at +1 907 265-2494.
What the light is like when you arrive
In summer, Anchorage gets up to 19½ hours of sunlight, and the sun sets just before midnight. A flight that touches down in the evening can still deliver a long, bright walk around town, with highs that typically average about 68°F and lows around 55°F.
Most people plan at least three days in Anchorage as part of a wider Alaska trip. Many vacation deals and tours also bundle motorcoach and train excursions, overnight stays and activities, so the arrival day is often the start of a longer itinerary instead of the whole visit.
What do you need for the trip?
You need valid photo identification that meets the REAL ID rules, or a passport. Flying from Denver to Anchorage is a domestic trip, so there is no customs line and no foreign entry paperwork, only the security checkpoint at the start.
REAL ID or a passport
REAL ID enforcement began on May 7, 2025. U.S. travelers must now be REAL ID compliant to board domestic flights and enter certain federal facilities. A license or ID with a star, or a flag, or one that says Enhanced, shows that it is ready.
A passport is an acceptable alternative and can be used in place of a REAL ID driver’s license or ID. If your Colorado license has no star, bring your passport, and keep it where you can reach it at the checkpoint.
If your ID is not acceptable
Travelers without an acceptable form of ID must pay a $45 fee under the TSA ConfirmID program. If your identity cannot be verified, you will not be allowed to enter the screening checkpoint, so it is worth looking at your license before the day you fly.
A temporary driver’s license is not acceptable. TSA currently accepts an expired ID up to two years after its expiration date, though the list of acceptable IDs is subject to change without notice.
Children and names on tickets
Adults 18 and older must show valid identification to travel. TSA does not require children under 18 to provide identification when flying within the United States, which keeps family trips simpler.
Unaccompanied minors who are eligible for TSA PreCheck must show an acceptable ID to receive expedited screening. TSA also accepts variations on name suffixes on boarding passes and ID, and a suffix is not required on the boarding pass.
Planning the rest of the trip
The free Official Anchorage Visitor Guide includes a business directory for Anchorage and Southcentral Alaska. Visitors can also book an Alaska Railroad trip, take a flightseeing tour or a day cruise, or stay in a remote Alaska lodge. You can sign up for the Anchorage e-newsletter for trip inspiration, travel deals and planning tools, a handy way to see what is on offer before you fly.
Good to know before you go
The best time to visit Anchorage runs from May to early September, which is also when the nonstop flights from Denver are described. Summer evenings stay light until just before midnight, so an arrival after dinner still leaves time for a stroll downtown, and a light jacket covers the cooler nights.
Keep your ID in an easy pocket, since it is the one item the checkpoint will not let you skip. Beyond that, a three-day stay gives you time to settle in before heading out to the rest of Alaska.
