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 handles about 94,000 boardings (roughly 185,000 total passengers) in a year.

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 245-plus instructors, flying a fleet that has since grown past 110 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 fleet is still growing. A 2025 Piper order for 145 more trainers (about $155 million, and Piper’s largest-ever domestic trainer order) pushes it toward 176 aircraft and devices by the mid-2030s.

That fleet does not fly cross-country. It flies touch-and-goes, all day, every weekday the weather allows. 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.

That record year carried a real cost, too. On October 18, 2021, UND student John Hauser died in a crash on a night training flight to Fargo. His family started a memorial fund for mental health in aviation.

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 training touch-and-go and an airliner landing each count as one operation. On the right day, Grand Forks genuinely competes with the country’s biggest hubs.

By passengers, there is no contest. Atlanta carried 104.7 million passengers in 2023 (the world’s busiest airport every year but one since 1998) against Grand Forks’ roughly 185,000 total. Atlanta moves more people in a single day than GFK moves all year.

Compared consistently, Atlanta handles roughly 570 times as many passengers as GFK: a huge gap, just not the 1,000-to-one figure sometimes quoted.

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.

Fargo’s Hector remains North Dakota’s passenger leader, with 516,071 boardings in 2023 as part of the state’s first million-plus year since 2016, while Grand Forks holds the operations crown.

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.

Inside there is free Wi-Fi, a sit-down restaurant and bar (the Red River Valley Tap House, serving breakfast through dinner plus specialty coffee) and a North Dakota- and UND-themed gift shop. Confirm current amenities and hours on the airport’s own site before you plan a meal around it.

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.

Commercial service comes from two carriers, and the lineup is (as of this writing) in flux. Delta flies to Minneapolis-St. Paul multiple times daily (64,760 passengers in the year ending January 2026, GFK’s busiest route) and added a fourth daily flight on April 13, 2026.

Allegiant, a distant second with Las Vegas, Phoenix/Mesa and seasonal Orlando/Sanford, paused all Grand Forks flying for summer 2026 in a systemwide pullback over falling Las Vegas demand, not its just-closed Sun Country merger, officials stressed. Routes return on a staggered schedule through spring 2027. Check the current airline list at GFK and the carrier’s own schedule before booking anything.

The airport also just 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.

GFK’s primary runway, 17R/35L, runs 7,351 feet, and the other two (3,901 and 3,300 feet) are too short for jets. A second air-carrier-capable runway means Delta and Allegiant can keep flying even after the main runway eventually needs rebuilding.

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. By passengers, Atlanta carries roughly 570 times as many people a year.

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 245-plus instructors, flying a fleet that has since grown past 110 aircraft. Airport officials put UND’s share of total operations at 90 to 95 percent.

What airlines currently fly out of GFK?

Delta serves Minneapolis-St. Paul year-round, multiple times daily. Allegiant’s Las Vegas, Phoenix/Mesa and seasonal Orlando/Sanford routes are paused for 2026, returning on a staggered timeline through spring 2027. Check current schedules before booking.

Can you watch planes at GFK?

Yes. The terminal is free, and the general aviation ramp is visible most weekdays during the school year. Watch from public landside areas; a clear weekday in-semester means a steady stream of training aircraft.

Is GFK the busiest airport in North Dakota?

By operations, probably (airport materials put GFK in the nation’s top 20 busiest), but we have not verified a year-by-year comparison against every North Dakota field, so treat it as directionally right rather than confirmed. By passengers, no: Fargo’s Hector carries far more travelers (516,071 boardings in 2023 versus GFK’s 93,815).
