McKinney National Airport (TKI) has spent years as the kind of place most people only notice if they fly private, work in corporate aviation, or live close enough to hear the runway rhythms on a busy day. That’s changing quickly. What was long known primarily as a general aviation reliever is actively building toward something bigger: commercial passenger service, a new terminal, and the infrastructure upgrades that turn an airfield into a regional travel option.
If you’ve wondered why McKinney keeps coming up in airport conversations lately, it’s because the city’s expansion plan has moved from “future idea” into active construction and signed agreements. A new commercial passenger terminal has already broken ground, and a first airline partner has now signed on—both are major milestones that signal the project is no longer hypothetical.
What McKinney National Airport Is Today
Right now, McKinney National Airport is a public airport owned by the City of McKinney and widely used for general aviation, including business and corporate flights. It serves as a reliever for the region’s larger commercial hubs by taking pressure off busier airspace and runways.
The airport’s runway (18/36) has been listed at about 7,000 feet in many reference sources, and the facility has seen a high volume of aircraft activity in recent years. Those details matter because runway length and airfield capacity influence what kinds of aircraft the airport can comfortably handle and what future airline operations look like.
The Big Shift: A Commercial Passenger Terminal Is Under Construction

The headline change is the new commercial passenger terminal. McKinney officials announced and celebrated the project’s groundbreaking on July 18, 2025, marking the start of a build that’s designed to bring scheduled commercial airline service to the area.
The terminal is planned at roughly 46,000 square feet and is designed to open with four gates, with the ability to expand to six as demand grows. That “start at four, expand to six” approach is a classic phased strategy: build what you can reasonably fill early, then scale once flights and passenger numbers justify it.
Key features described by the City of McKinney include centralized food and beverage concessions, open hold rooms, onsite rental car facilities, a deicing area for winter operations, and supporting infrastructure like a new taxiway to improve airfield efficiency.
The plan also includes a 980-space public parking lot that can expand to 1,450 spaces.
The First Airline Partner: Avelo Signs On
One of the most meaningful indicators that commercial service is moving forward is the first airline agreement. On December 16, 2025 reporting, Community Impact stated that McKinney National Airport’s future commercial terminal has its first airline partner after the city signed an Airline Use and Lease Agreement.
Multiple reports identify Avelo Airlines as that first airline partner. Routes and exact start dates have not been consistently detailed in the reporting, but the agreement itself is a major step because it establishes operating terms and signals real intent to serve the airport once facilities are ready.
Runway Work: An Extension Is Underway

While the terminal gets most of the attention, runway work is one of the most practical parts of expansion. The City of McKinney’s construction updates indicate the airport is extending Runway 18/36 by 500 feet at the north end, with notes about a settlement period and an anticipated completion window around October 2026.
Runway projects are the unglamorous backbone of airport growth. A longer runway increases operational flexibility, supports heavier aircraft at a wider range of temperatures, and improves performance margins—especially important when an airport is preparing to host commercial operations alongside existing business aviation.
International Capability: A Dedicated U.S. Customs Facility Opened
Another notable development is that McKinney National Airport opened a dedicated U.S. Customs and Border Protection facility on September 22, 2025, according to the city’s announcement.
Community Impact also reported on the opening and described the facility as supporting more efficient processing for international travel needs.
This is a significant signal even before commercial passenger flights begin. It strengthens the airport’s usefulness for corporate and private international arrivals and can make the airport more attractive for business aviation operations that value speed and convenience.
What Capacity Looks Like and Why the Numbers Keep Coming Up
City materials describe the terminal as expected to initially serve around 200,000 passengers annually, with expanded gate capacity able to support more than one million travelers per year.
That doesn’t mean McKinney is trying to become “the next DFW Airport.” It means the city is building an airport with room to grow into regional demand over time, rather than locking itself into a too-small terminal on day one.
It also explains why the airport has become a hot topic locally. Projects that bring commercial service also bring new traffic patterns, new noise maps, and a different kind of public attention than a business-aviation-heavy airfield tends to generate.
How This Fits Into the Metroplex Airport Ecosystem
In North Texas, most travelers default to two major commercial choices: Dallas-Fort Worth International (DFW) and Dallas Love Field. McKinney’s pitch is not “replace them,” but “add another option,” especially for the fast-growing northern edge of the region where driving time to the big airports can feel like half the trip.
If commercial service launches as planned, McKinney could become a practical alternative for certain routes—particularly the kinds of leisure-friendly, point-to-point flights that low-cost carriers often specialize in. The fact that the first airline partner reported is Avelo fits that potential travel pattern.
Tips for Locals: What to Watch Over the Next Year
If you’re tracking the project like a local (or planning your future “closer airport” strategy), these are the details most likely to shape how useful the airport feels when it starts commercial service:
Watch for route announcements and launch dates from the first airline partner once the terminal timeline tightens.
Keep an eye on the runway extension schedule and any operational notices while construction continues.
Look for updates on concessions, parking logistics, and ground transportation access, because those details determine whether an airport feels smooth or stressful in real use.
Final Thoughts
McKinney National Airport is in the middle of a clear transition: it’s still a high-activity general aviation airport, but it’s now building the pieces that support commercial passenger flights—a new terminal, runway improvements, and supporting infrastructure.
With a first airline agreement now reported and construction already underway, the airport’s next era is no longer a distant plan; it’s actively taking shape.
