The Two-Gate Airport That Out-Landed Atlanta
Grand Forks International really has finished first in the country for takeoffs and landings. It is also a two-gate airport in a city of about 59,000. Both are true, and the distance between them is the story.
Yes: on certain days, by one narrow measure, Grand Forks International Airport has out-landed Atlanta’s Hartsfield-Jackson and Chicago O’Hare.
It is also a two-gate airport that recorded 93,815 passenger boardings in 2025, including charters, according to its own historical table.
Neither sentence cancels the other. What sits in the gap is the part worth knowing before you repeat the trivia.
The claim is real: GFK has beaten Atlanta on a stopwatch
In early 2021, FAA tower counts put Grand Forks International in the No. 1 spot nationwide for daily operations (takeoffs plus landings) on March 1, 2 and 3, and again on March 8, with the FAA confirming the streak. The Grand Forks Herald later put the March total at five No. 1 days and a season-high 2,054 operations, and reported that April 27 topped 2,200. Airport data show GFK actually finished first nationally 11 separate times across all of 2021, not just that spring.
Jeremy Roesler, the University of North Dakota’s chief flight instructor at the time, told UND Today: “given that the United States is home to the world’s busiest airports, we might have been No. 1 in the world earlier this month.”
The full year was the airport’s best on record by that measure. GFK finished 2021 as the 12th-busiest airport in the country by total operations: 349,405 takeoffs and landings, its highest ranking ever, per airport data reported by the Herald. Atlanta led with 707,661 that year, O’Hare 684,201, Dallas-Fort Worth 651,895, and Seattle-Tacoma edged out Grand Forks at No. 11 with 374,510.
A city of about 59,000, in a metro of roughly 104,000, finished ahead of every airport in the country except eleven.
The reason is not passengers. It is flight students.
The mechanism is not complicated, just enormous.
UND’s John D. Odegard School of Aerospace Sciences runs its flight training program out of GFK. In 2021 that meant roughly 1,400 students on the schedule, backed by roughly 250 instructors. The university’s current fleet page lists more than 100 aircraft. Between July 2020 and June 2021 they flew a record 126,000 training hours, beating 2013’s 110,000 and topping what had been treated as a 120,000-hour ceiling.
The school is renewing its fleet. Piper’s 2025 announcement describes an initial order for 145 trainers over eight years beginning in 2027, with an option that could take deliveries to 188 through 2036. Piper described UND’s fleet as already totaling 176 aircraft and training devices in 2025. That is not a future aircraft-only total, and an order can replace existing airplanes as well as add capacity.
Repeated training circuits help explain the busy tower. The fleet also makes cross-country flights, as UND's flight policies make clear. Airport officials put UND’s share of total operations at 90 to 95 percent depending on the year.
One instrument student can rack up a dozen landings before lunch. Multiply that by well over a thousand students and a small-town tower can out-count Atlanta’s jets on operations alone. Atlanta counts one operation per airliner full of people. Grand Forks counts one per single-engine trainer carrying a student and an instructor.
Not a one-year fluke, and not without cost
The record year was a peak, not an accident. GFK’s national ranking has swung from roughly 12th to 33rd over the past decade and a half: 17th in 2012, up from 21st the year before; a slower 33rd in 2019; a pandemic dip to 20th in 2020, when it still took the No. 1 spot for a day that June with 1,200-plus operations because everywhere else had collapsed further.
Operations were already near 2,000 a day before the pandemic, by airport-reported counts, putting GFK “in the top five nationally” by February–March 2020.
The airport’s own materials describe the standing more modestly, as “often ranked in the top 20 busiest,” so treat “North Dakota’s busiest, every year” as directionally right but unverified.
The training community also suffered a loss that year. UND student John Hauser died on October 18, 2021. His family established the John A. Hauser Mental Health in Aviation Initiative Fund, which supports student mental-health and peer-support work.
The asterisk: operations and passengers are not the same contest
“Busiest” can mean two different things, and GFK only wins one of them.
By operations (what tower counts measure), a landing and a takeoff each count separately. A training touch-and-go counts as two operations, one landing followed by one takeoff. The size of the aircraft and the number of people aboard do not change that count. On the right day, repeated training flights put Grand Forks alongside the country’s biggest hubs.
Correction, September 4, 2026: An earlier version counted a touch-and-go as one operation and incorrectly said UND's training fleet does not fly cross-country. FAA counting instructions distinguish the landing and takeoff; UND's policies describe cross-country flying. Other historical and operational figures retain their September 2 check date.
By passengers, the headline means something different. An airport can record thousands of training movements without thousands of airline travelers passing through its terminal. Boardings count departing passengers; total passenger traffic includes arrivals too. Those measures should not be mixed to manufacture a dramatic ratio.
GFK’s passenger side has also had a rougher decade than its operations side. Enplanements peaked at 148,802 in 2013, fell 21 percent to 117,925 by 2019 (the same years operations were climbing toward the 2021 peak), then crashed to 46,891 in 2020. They have since recovered to 93,815 in 2023, dipped to 91,922 in 2024, and returned to 93,815 in 2025, still below the 2013 and 2019 highs.
For a consistent statewide passenger comparison, the North Dakota Aeronautics Commission’s 2025 report lists 590,542 airline boardings at Fargo’s Hector and 91,936 at Grand Forks. The commission’s airline series differs from GFK’s historical table, which includes charters. Fargo is the clear passenger leader; GFK’s national headline concerns aircraft movements.
Correction, September 8, 2026: The 176-aircraft-and-device figure described UND’s fleet in Piper’s 2025 announcement, not a future fleet target. We also replaced a loosely sourced passenger ratio and an incorrect statewide million-passenger milestone with an explicitly labeled, same-source comparison. The airport’s repeated 93,815 boarding total for 2023 and 2025 is confirmed in its own table.
So the claim is true, and genuinely fun trivia. It is also true only in a narrow technical sense: the part a travel writer owes you before you pass it along. “GFK has been the busiest airport in America, by operations, on at least 12 documented days” is accurate. “GFK is a busier airport than Atlanta” is not.
This is a record that rewards a closer look: true, and even better understood in full. The same is true of the state’s other headline claims, from the biggest ones checked against the record to the KVLY-TV mast near Blanchard, each one worth the same closer look.
What you will actually see
GFK is a small, welcoming, two-gate terminal built around a working flight-training ramp, worth seeing for exactly what it is.
Its home is the Byron L. Dorgan Terminal (about 50,000 square feet, two gates and 1,087 parking spaces, opened in 2011), small enough to walk end to end in minutes, with easy in-and-out parking and none of the hassle of a big hub.
The Red River Valley Tap House serves both sides of security and welcomes people who are not flying. The airport says it opens one hour before the first departure and closes after the final boarding call, so hours follow flight activity. It also lists coffee, food, drinks and gifts. Check directly before planning a meal around the stop.
The real draw is outside, on the general aviation ramp: single-engine Pipers and Cessnas, twin-engine Seminoles and UND’s Beechcraft King Airs cycling through pattern work, sometimes with helicopters mixed in. The FAA’s own chart supplement warns pilots of “heavy student training activity within 15 miles of the airport.” That warning is the visitor attraction.
The airport’s airline directory lists Delta service to Minneapolis-St. Paul and Allegiant service to Las Vegas, Phoenix/Mesa and seasonal Orlando/Sanford. A listed destination does not mean flights operate on every date. Use the airline’s booking calendar for your travel dates before choosing an airport or making hotel plans.
Airline information updated September 4, 2026: this summary reflects the routes listed by the airport, not a confirmation of service on a particular day. It replaces an earlier statement that described all Allegiant routes as paused for 2026.
In 2024, the airport finished a nearly $70 million project extending its crosswind runway, 9L/27R, 2,500 feet west to 6,701 feet; it reopened October 16, 2024. Training aircraft already used that runway. What is new is that airliners can use it too.
The airport’s current fact sheet lists primary runway 17R/35L at 7,349 feet and the shorter general aviation runways at 3,900 and 3,300 feet. The extended crosswind runway gives the airport a second option for airline operations when wind or maintenance limits use of the primary runway.

Frequently asked questions
Is Grand Forks International Airport really the busiest airport in the U.S.?
Sometimes, by one measure. GFK topped the country’s daily tower-operations count on at least 12 documented days in 2020–2021, and it was the 12th-busiest U.S. airport in 2021. That is an aircraft-movement ranking, not a passenger ranking.
Why does a small North Dakota airport have so much air traffic?
UND’s flight-training program flies out of GFK. In 2021 that meant around 1,400 students and roughly 250 instructors. The university’s current fleet page lists more than 100 aircraft. Airport officials put UND’s share of total operations at 90 to 95 percent.
What airlines currently fly out of GFK?
The airport lists Delta to Minneapolis-St. Paul and Allegiant to Las Vegas, Phoenix/Mesa and seasonal Orlando/Sanford. Route listings do not establish availability on a particular day. Check Delta’s or Allegiant’s booking calendar for your travel dates.
Can you watch planes at GFK?
The terminal’s restaurant welcomes non-flying visitors. Ask airport staff about views available from public landside areas. The training ramp is restricted, and traffic varies with weather and teaching schedules.
Is GFK the busiest airport in North Dakota?
GFK describes itself as often among the nation’s top 20 airports by operations; this article does not establish an unbroken statewide annual record. By airline boardings, Fargo leads: the state’s 2025 report lists 590,542 at Hector and 91,936 at GFK.
