## At a glance
- Non-weather ATC delays rose 142% between 2015 and 2025 while scheduled passenger flights grew only 4.9%, indicating structural capacity problems.
- Total cumulative cost of ATC delays: USD 10.9 billion (2015–2025), with airlines bearing USD 9.2 billion and passengers USD 1.7 billion.
- Delays accelerated sharply: 40% year-on-year increase from 2024 to 2025, reaching 7.1 million minutes.
- Volume-related delays accounted for 57% of total costs; runway capacity shortages added USD 5.6 billion separately.
- Ten major FAA facilities generate 61% of delay minutes and 64% of total costs, identifying key system bottlenecks.

## What the report covers
IATA's analysis quantifies the economic impact of air traffic control delays in the US National Airspace System from 2015 to 2025. The report examines delay causes, magnitude relative to traffic growth, and costs borne by airlines and passengers. It identifies structural capacity challenges beyond traffic increases and the costliest delay categories and facilities.

## Key findings
Non-weather ATC delays increased 142% from 2.9 million to 7.1 million minutes annually between 2015 and 2025, despite scheduled passenger flights growing only 4.9%. This disproportionate growth reveals underlying capacity and operational challenges have become structural. The acceleration intensified recently: delays jumped 40% year-on-year from 2024 to 2025, from 5.0 to 7.1 million minutes.

US government shutdowns between October and November 2025 created severe staffing shortages, driving 27% of all non-weather ATC delays and 34% of non-weather delay minutes. Staffing issues, recorded in the 'Other' category, contributed 38% of cumulative delay costs from 2015 to 2025, demonstrating the vulnerability of system performance to personnel gaps.

Cumulative economic cost of ATC delays totalled USD 10.9 billion in 2025 prices from 2015 to 2025. Airlines bore 84% (USD 9.2 billion) while passengers bore 16% (USD 1.7 billion). Volume-related delays generated 57% of total costs, Other causes 38%, and Equipment 5%. Runway capacity shortages incurred additional USD 5.6 billion.

Ten FAA facilities with the longest delays generate approximately 61% of total delay minutes and 64% of total costs. This concentration identifies specific regional bottlenecks where capacity and operational improvements yield proportionally large system-wide benefits.

## Key numbers
| Metric | Value | Note |
|---|---|---|
| Non-weather ATC delay growth, 2015–2025 | 142% increase | From 2.9 million minutes (2015) to 7.1 million minutes (2025) |
| Scheduled passenger flight growth, 2015–2025 | 4.9% increase | Observed actual growth in number of scheduled flights |
| Year-on-year delay increase, 2024–2025 | 40% increase | From 5.0 million minutes (2024) to 7.1 million minutes (2025) |
| Total cumulative delay cost, 2015–2025 | USD 10.9 billion | In 2025 prices; airlines USD 9.2 billion (84%), passengers USD 1.7 billion (16%) |
| Staffing-related delays during government shutdowns | 27% of non-weather delays; 34% of delay minutes | October 1 – November 12, 2025 |
| Runway capacity shortage cost, 2015–2025 | USD 5.6 billion | Tracked separately from Volume and Other categories |
| Cost distribution by delay category | Volume 57%, Other 38%, Equipment 5% | Breakdown of USD 10.9 billion cumulative cost |
| Top 10 FAA facilities concentration | 61% of delay minutes; 64% of total costs | Identifies key bottlenecks in National Airspace System |

## Why it matters
**DMOs & destinations** — ATC delays degrade air service reliability to US destinations, threatening schedule consistency and passenger satisfaction. Persistent congestion at ten major facilities undermines destination competitiveness. DMOs should monitor capacity constraints at gateway airports and advocate for airspace modernisation.

**Hotels & hospitality** — ATC delays increase passenger arrival unpredictability and reduce check-in timing accuracy. USD 1.7 billion in cumulative passenger delay costs may suppress demand and displace bookings. Hotels dependent on US air access face operational planning challenges from worsening system performance.

**Travel tech & distribution** — Rising delays complicate schedule optimisation and increase rebooking frequency for booking platforms and GDS systems. Growing delay volatility requires better reliability prediction tools and improved itinerary algorithms. Platforms must account for system-level capacity constraints when competing on flight times and connection reliability.

## Methodology and limits
IATA analysed FAA OPSNET data covering all National Airspace System delays from 2015 to 2025, including commercial passenger, air taxi, general aviation, and military operations. Delay causes are categorised by FAA taxonomy (Volume, Equipment, Runway, Other). Economic impact was modelled using fleet cost, fuel, crew, maintenance, passenger care, time value, delay duration, and flight stage, accounting for non-linear cost escalation with delay length. This brief is based on the publicly available summary.
