(DENVER, COLORADO, USA) Airlines and Denver International Airport moved Friday to blunt the immediate impact of federal air-traffic staffing shortfalls, as officials confirmed a rolling schedule of flight reductions that began at 4% and will rise to as much as 10% by November 14. The measures, in effect from 6 a.m. to 10 p.m. local time, prompted carriers to preemptively cancel flights and offer refunds well beyond standard policies, while airport leaders pressed federal partners for flexibility to keep planes moving through one of the nation’s busiest hubs.
Airlines’ immediate actions and refund policies

United Airlines said it started canceling about 4% of its daily schedule through Sunday — roughly 20 round trips per day, primarily on United Express. A spokesperson said the airline used internal tools to “find flights that would be cancelled with the least possible disruption to customers,” and added that travelers whose itineraries changed “were immediately notified.” United also announced that “all customers traveling during this time are eligible for a refund without penalty, even if their flight isn’t affected,” a blanket offer that goes further than typical waivers tied only to canceled or significantly delayed flights.
Other carrier responses:
- Delta: Adopted the same broad policy for trips touching impacted airports, allowing customers to claim full refunds without change fees or narrow eligibility windows.
- Southwest, American, Alaska: Confirmed they will provide refunds for canceled flights.
- Frontier (headquartered in Colorado): Allows refunds for:
- Domestic flights canceled or delayed more than three hours
- International flights canceled or delayed more than six hours
Airlines are pushing real-time status updates through their websites and mobile apps and urged passengers to check digital channels before leaving for the airport.
Why the cuts are happening and airport response
Airport leaders said the steps were necessary as the shutdown strained the air-traffic control workforce and limited capacity, with the effect most visible during daytime peak hours. Phil Washington, CEO of Denver International Airport, warned staffing issues are being identified at many airports and said controllers were being “stressed unnecessarily.”
The airport asked the Federal Aviation Administration (FAA) whether it could use airport revenue to pay controllers during the shutdown and seek reimbursement later — a stopgap that would require federal approval and accounting safeguards.
“This is a critical time for travel both here at DEN and around the country,” — Phil Washington, CEO, Denver International Airport
National concerns and scale of reductions
Transportation leaders warned of broader national strain if the budget stalemate persists. U.S. Transportation Secretary Sean Duffy cautioned there would be “chaos in the skies” if air traffic controllers miss another paycheck, highlighting the risk that staffing losses or missed shifts could ripple across already tight schedules.
By Friday, airlines had cut more than 760 flights from nationwide schedules — about four times Thursday’s totals — and planners expected those numbers to increase as the flight reductions directive expands to up to 10% at Denver International Airport next week.
What travelers should do now
Carriers said they are proactively notifying customers when a flight falls under the reduction order and, when possible, shifting them to earlier or later departures.
Practical advice for passengers:
- Monitor the airline’s app and website repeatedly during the 24 hours before departure.
- Consider requesting an earlier flight if you have a tight connection or same-day return.
- If reliability is crucial, choose the first flight of the day when possible.
- For some, consider alternative ground travel if schedules become too uncertain.
VisaVerge.com analysis suggests people with tight connections or same-day returns should ask for earlier options rather than risk missed segments later in the day, especially while cuts run through peak hours.
How refund policy differences matter
The split among carriers’ refund policies affects families and workers who cannot wait out uncertainty:
- United and Delta: Broader approach — refunds allowed even if flights still show as operating, giving customers flexibility to cancel or change modes.
- Southwest, American, Alaska: Refunds for canceled flights only — customers must watch whether a specific flight is removed.
- Frontier: Clear thresholds (domestic >3 hours, international >6 hours) for eligibility.
Airlines said call centers and online tools will handle requests but warned that phone wait times could be long during peaks.
Ground-side impacts and passenger behavior
Rental car managers expect a surge in demand as cancellations stack up. Nearly a dozen rental agencies operate at the airport, using 12,760 parking spaces, and travelers often opt to drive — a six- or eight-hour drive can feel more reliable than a two-hour flight with uncertain timing.
- Passengers can sometimes make same-day switches using travel wallets funded by refunds or credits.
- Airlines have not promised ground transportation assistance.
FAA cap details and where to find updates
The FAA’s reduction order began at 4% on Friday and is scheduled to increase to 10% by November 14. The cap applies daily during the defined hours and forces schedule cuts across all commercial carriers at Denver International Airport. Daytime capping is intended to protect safety margins while traffic towers operate with fewer controllers.

How carriers choose cancellations to limit harm
Airlines are using early, targeted cancellations to preserve predictability elsewhere in their networks. Tactics include:
- Trimming mostly regional/feeder frequencies (e.g., United Express) to keep mainline, long-haul flights intact.
- Using technology that models:
- Connection flows
- Crew-rest rules
- Airport-specific capacity limits
This approach may lead to smaller cities seeing outsized changes on some days while key trunk routes remain operational.
Human impact and passenger strategies
The immediate human impact is clear: hourly workers, families, and those with time-sensitive commitments (weddings, interviews, medical appointments) face disruption.
- Expanded refunds and free rebooking are helping those who need guaranteed arrival times.
- Travelers are increasingly booking red-eyes to avoid the daytime cap, though overnight seats are filling fast.
- Many are shifting trips by a day or two given greater flexibility from airlines.
Airport operations and contingency planning
Denver International Airport will keep terminal staffing strong to guide passengers with short-notice changes. Airport teams are also coordinating with airlines on gate management to reduce crowding around heavily impacted flight banks.
Phil Washington emphasized the airport’s request to use airport revenue for controller pay is part of broader efforts to keep essential services stable until federal funding resumes.
What to expect in the coming days
Schedule watchers predict:
- Rolling cancellations announced the night before travel
- Same-day retiming to match cap windows
- Frequent status changes — keep your phone on and check airline apps
With more than 760 flights cut on Friday alone and the cap set to grow, digital monitoring remains the best early warning. The coming week will test whether pre-planned cancellations align with actual traffic flow as the cap climbs toward 10% at Denver International Airport and whether the expanded refunds sufficiently ease disruptions for those who cannot delay travel.
This Article in a Nutshell
Denver International Airport and airlines implemented schedule cuts after the FAA ordered daytime flight reductions beginning at 4% and rising to 10% by November 14. Carriers preemptively canceled flights—United removed about 20 round trips daily—and expanded refund options, with United and Delta offering broad refunds even if flights remain scheduled. Airport leaders sought FAA permission to use airport revenue to pay controllers temporarily. Travelers should monitor apps, opt for earlier flights, and expect rolling cancellations and frequent status changes.
