United Airlines just finished phase one of a multiyear expansion at its Denver Flight Training Center, the sole campus that qualifies and recertifies the carrier’s nearly 18,000 pilots. The airline says the facility can now train up to 860 pilots a day across 86 CAE devices, including 52 full-motion simulators.
For travelers, the story is not a new route map. It is capacity behind the scenes at United’s fastest-growing hub. More simulator bays and a second campus planned near Denver International Airport are how the airline says it will keep hiring and recurrent training from becoming a bottleneck as Denver flying grows.
- Milestone: Phase one complete at United’s Denver Flight Training Center.
- Devices: 86 CAE units, including 52 full-motion simulators.
- Throughput: Up to 860 pilots a day and more than 32,000 events a year.
- Campus size: Eight buildings and nearly 700,000 square feet on 22 acres.
- Next: Phase two near DEN targeted for 2027 groundbreaking and 2030 operations.
What United and CAE completed in August 2026
According to United’s Aug. 20, 2026, announcement, the airline and CAE celebrated phase one after adding 40 new training devices since 2022. The Central Park campus in Denver now holds 52 full-motion simulators and 34 fixed devices.
United calls the site the world’s largest pilot training facility and the only place its active and newly hired pilots complete required simulator work. Pilots return about every nine months after initial qualification.
Independent local reporting from the Denver Post confirmed the same device counts, daily capacity, and on-site celebration at 7500 E. 35th Ave., with simulators framing the event floor.
Why Denver travelers should care about training capacity
United is operating an airport-leading summer average of about 570 daily departures from DEN and says it has invested nearly $1 billion in customer-facing Denver projects since 2021, including gates, clubs, and a new check-in lobby. Training capacity is the less visible half of that growth story.
If simulator seats fall behind hiring and aircraft deliveries, airlines delay new-hire classes or stretch recurrent schedules. Travelers feel that later as thinner reserve coverage and harder recovery after weather. United’s claim of 860 pilots per day is the operational buffer it wants against that risk.
The airline also notes nearly $40 million in Denver hotel nights for visiting pilots in 2025, with about $50 million expected in 2026. That is a local-economy side effect of concentrating training in one city, not a passenger product.
Phase two near Denver International Airport
In July 2026, Denver City Council approved rezoning for two parcels United bought in 2023 near DEN. United says formal site plans are underway, with groundbreaking expected in 2027 and operations around 2030. The new campus would run with the existing Central Park facility rather than replace it.
That second site is the planning signal for the rest of the decade. Phase one finished the current campus scale. Phase two is how United says it will keep expanding training as Denver remains its fastest-growing hub and pilot hiring continues under United Next.
United says it has hired more than 9,500 pilots since announcing United Next in 2021, including 700 so far in 2026, with hundreds more planned this year across First Officer hiring, Aviate pathways, the United Aviate Academy, and a military pilot program.
Local jobs, hotels, and the Central Park campus footprint
United says more than 1,600 of its 11,400-plus Denver-based employees work at the Flight Training Center across 24 departments, from instructing and evaluating to scheduling, hiring, human resources, and flight standards. A 2024 building that cost more than $145 million supported more than 300 new jobs after opening.
Concentrating every United pilot through one city creates a steady hotel demand curve. United expects about $50 million in Denver hotel nights for training visits in 2026 after nearly $40 million in 2025. That is useful context for Denver lodging demand near Central Park, not a reason to change a passenger itinerary.
The campus itself dates to the late 1960s Stapleton complex and has remained United’s main pilot school since then. United says it has invested about $370 million in the Flight Training Center since 2016, with phase one as the latest finished block in that long rebuild.
How this connects to United Next hiring
United frames the expansion as support for United Next growth rather than a one-off construction ribbon cutting. Since 2021 the airline says it has hired more than 9,500 pilots. In 2026 alone it reports 700 hires so far and plans for hundreds more through First Officer hiring, Aviate pathways, the United Aviate Academy in Goodyear, Arizona, and a military pilot transition program.
About 4,500 of United’s nearly 18,000 pilots are veterans, according to the same announcement. The training campus has to absorb initial qualification and recurrent checks for that whole workforce, which is why device count and daily throughput are the load-bearing metrics in the story.
What is confirmed and what remains open
Confirmed from United: phase one completion, 86 CAE devices, 860 pilots per day capacity, eight buildings, nearly 700,000 square feet, 22 acres, and a phase-two path near DEN for 2027 to 2030. Confirmed from the Denver Post: the same campus numbers and the Aug. 20 event framing.
Still open: the exact groundbreaking date for phase two, how many additional devices that campus will hold, and whether any interim construction work changes access around the Central Park site for employees or neighbors. None of those unknowns change the passenger booking path for DEN flights today.
AirlineGeeks also summarized the same official figures after the announcement, reinforcing that the story is a capacity milestone rather than a schedule change travelers can buy tomorrow morning. For United product rules that do affect a booking today, use Deep Arrival’s United Airlines guide for baggage, boarding groups, and Basic Economy details while treating this training story as background on hub staffing capacity.
United also says it hired more than 1,400 people in Denver last year and plans to hire more than 1,300 in 2026 across the hub, not only at the training campus. That broader Denver hiring figure sits beside the simulator story as evidence that the airline is staffing the whole DEN operation while it expands training hardware.
None of those employment numbers change how a passenger checks a bag or boards at DEN tomorrow. They do explain why United keeps spending on a single-city training machine while it markets Denver as its fastest-growing hub.
| If you care about | What to do |
|---|---|
| United growth reliability at DEN | Treat phase one as training capacity already online, not a route launch |
| Longer-term Denver hub plans | Watch phase-two groundbreaking near DEN in 2027 |
| Pilot career paths into United | Use United’s published First Officer, Aviate, Academy, and military channels |
| Near-term DEN trip planning | Keep using live schedules and airport advisories; this does not change gates today |
Watch for United’s phase-two groundbreaking notice near DEN, any updated device counts after additional simulator deliveries, and Denver permitting updates that could shift the 2030 operations target.
