Midway keeps full route files for 73 US airports, the busiest in the country, and Denver International (DEN) is the only one of them with a nonstop to every one of the other 72. Its own list for the next twelve months holds around 200 US airports, level with Chicago O’Hare and a little ahead of Dallas-Fort Worth. For a distributed team that is the practical reason Denver keeps appearing on shared lists: whichever large airport an office flies from, it has a nonstop to Denver.
Each count on this page is the number of US airports in an airport’s own nonstop list, with a flight in at least one month from October 2026 to September 2027. Puerto Rico and the US Virgin Islands are left out. Denver’s list also includes Fort Collins-Loveland (FNL), 44 miles away with a 1h05 trip on a carrier code that is most likely a ground connection, and that entry is not counted.
What there is to do in Denver, hotel rates and flight times from the coasts are in the Denver city profile. This page covers the flight side only: how Denver’s reach compares with the other hubs in the middle of the country, and which airports cannot get there nonstop.

Denver and the other central hubs
The comparison uses the large connecting airports in the middle of the country: Chicago O’Hare (ORD), Dallas-Fort Worth (DFW), Houston Intercontinental (IAH) and Minneapolis-St Paul (MSP), with St. Louis (STL) and Kansas City (MCI) as the mid-size options. Atlanta (ATL) is not central, but it sits next to Denver at the top of the ranked list of US offsite cities, so it is in the table for reference. Each is a single airport, so Chicago’s second airport (MDW), Dallas Love Field and Houston Hobby are not added in.

*From Midway’s route data as of 26 October 2026. The first column is exact: of the other 72 US airports with a full route file, how many have a nonstop to or from the hub. The other columns are rounded to the nearest 5. “In every month” counts US airports listed in each month from October 2026 to April 2027. The last column counts routes with more than one airline, with American, Alaska and Hawaiian taken as one because they sell seats on each other’s flights.
Denver, O’Hare and Dallas-Fort Worth are close on the size of their US lists. The difference for a team is which large airports are missing. O’Hare has no nonstop from Burbank, Oakland, Dallas Love Field, Houston Hobby or Chicago’s second airport, mostly Southwest airports. Dallas-Fort Worth misses Oakland and Love Field, and Atlanta misses Oakland. Denver is a United hub, and Southwest flies around 90 of its US routes and Frontier around 45, so it sits on both sides of that split.
The last column is where O’Hare leads. Around 125 of its US routes have two or more airlines, because American and United both run a hub there. Denver has around 90, and Dallas-Fort Worth and Atlanta, each mostly one airline’s hub, have around 35 and 45. A second airline gives the team a second schedule to book against. The route data lists the airlines on a route but not fares, so it cannot say how much that changes the price.
Airports that only Denver reaches
Around 45 US airports have a nonstop to Denver and to none of the other seven hubs in the table. Most are small airports in the Mountain West and the Plains, on United’s regional flights, Denver Air Connection or Contour: Helena, Butte, Moab, Telluride, Pueblo, Dodge City and Williston, among others. Oakland and Long Beach on Southwest, and Lihue on Kauai, are on the same list. So are seven Wyoming airports, among them Cheyenne, Casper, Laramie and Sheridan, and for a team member flying from one of those Denver is the one hub in the table with no connection.
The other direction is longer. Around 105 US airports have a nonstop to O’Hare or Dallas-Fort Worth and none to Denver, most of them smaller airports in the East, the Midwest and Texas: Allentown, Manchester (New Hampshire), Roanoke, Green Bay, South Bend, Baton Rouge, McAllen and Corpus Christi. Someone flying from one of those connects, and O’Hare and Dallas-Fort Worth both fly to Denver. For a team with several people in that position, the direct flights vs connections guide covers how to decide who connects and where.

Months and seasons
Denver’s US list moves little through the year. From October 2026 to April 2027 it holds between around 185 and 190 US airports each month, and around 180 of them are listed in every one of those months. A few routes are seasonal: West Palm Beach runs from October to April, Bishop (for Mammoth) from December to April, and Fairbanks from May to August. So an offsite planned for spring or autumn sees much the same list.
The “every month” window stops at April 2027 because Frontier, Sun Country and Avelo schedules end there in the data, and Southwest’s end after August. That looks like schedules not yet loaded rather than cuts: 6 of the 8 Denver routes listed in August and not in September are flown only by Southwest. Check the month again in Midway before booking an offsite after April. Denver’s winter storms and ski-season hotel prices are a separate question, covered in the Denver city profile.
What the counts leave out
The counts say which airports reach Denver. They do not say how long each office flies: New York to Denver takes around 4h30 and San Francisco to Denver around 2h40. The coast-split guide covers that balance for a team on both coasts. The data also records whether a route runs in a month and its fastest time, not how many flights a day, so it cannot tell a route with one flight a week from one with ten a day.
Venue, hotel and cost rows are for the team to fill in. The offsite destination comparison template has a filled-in example where Denver and Dallas-Fort Worth come out ahead on the flight rows. The cluster page has the full method, from team roster to shortlist.
