Global Airport Disruption
Q1 2026
The first quarter of 2026 produced the largest single-quarter cancellation step-up in modern commercial-aviation tracking. This synthesis consolidates Cirium, IATA, EUROCONTROL, and FAA datasets on the most-affected airports and the cause mix.

Executive summary
Cirium's March 2026 Monthly On-Time Performance release recorded 92,523 global cancellations in March, up from 43,904 in February — a 111% month-over-month rise and the largest sequential cancellation step-up in the dataset's published history. The cause concentration is unusually clean: Middle East hub restrictions following the late-February Gulf cascade account for the bulk of the March increment.
Approximately 5 million passengers were affected between February 28 and March 11. March 11 alone produced roughly 18,000 global delays — Cirium's reported single-day peak for the year so far. Within a week of the first restrictions, more than 15,000 flights had been cancelled, principally concentrated at Dubai (DXB), Doha (DOH), and Abu Dhabi (AUH), with secondary effects across nearby state airspaces that imposed restrictions on overflights.
Recovery has been steady. By early April cancellation rates had fallen into the 10-11% band; by mid-April Cirium reported normalisation across most affected hubs. The UAE security corridor, declared in early May 2026, brought structured one-way transit back to the Gulf region — see UAE corridor briefing.
Structural vulnerabilities exposed by the quarter — tight aircraft and crew schedules, limited spare capacity at primary hubs, aging ATC and airport infrastructure in several regions — were also called out by Cirium and IATA as recurring themes that compound any specific disruption trigger.
Monthly cancellation trajectory
Q1 2026 monthly cancellations (global)
January 2026 ran broadly in line with the four-year January baseline. February showed a mild upward drift consistent with seasonal European winter operations. The March step-up is the anomaly: 92,523 global cancellations versus a baseline expectation in the high-40,000s. Of that increment, the bulk is attributable to Middle East hub restrictions following the late-February Gulf cascade (see Gulf 12-FIR briefing).
Single-day disruption peaks
| Date | Event | Global delays / cancels |
|---|---|---|
| Feb 28 | Gulf cascade onset, DXB/DOH curtailment | ~12,000 cancellations within 24h |
| Mar 3 | Iran CZIB 2026-02 full effect on adjacent FIRs | ~14,000 delays |
| Mar 7 | DXB drone-impact series (Cirium "extended" tag) | ~11,500 delays |
| Mar 11 | Crisis-day peak | ~18,000 delays |
| Mar 30 | DXB second drone-impact event | ~9,000 delays |
Top-10 most-affected airports
Cirium's hub-level breakdown attributes the bulk of the March step-up to Middle East airports closing or restricting operations during the late-February cascade. Most-affected list below reflects the share of scheduled operations that ran more than four hours late or were cancelled outright over the 30-day window Feb 28 – Mar 30.
| Rank | Airport | Region | Primary cause | Disruption tier |
|---|---|---|---|---|
| 1 | DXB Dubai | Gulf | Airspace events + drone-impact series | Severe |
| 2 | DOH Doha | Gulf | Airspace events, hub curtailment | Severe |
| 3 | AUH Abu Dhabi | Gulf | Airspace events | Severe |
| 4 | RUH Riyadh | Gulf | Adjacent-FIR restrictions | Significant |
| 5 | KWI Kuwait | Gulf | Adjacent-FIR restrictions | Significant |
| 6 | BAH Bahrain | Gulf | Adjacent-FIR restrictions | Significant |
| 7 | MCT Muscat | Gulf | Increased transit / overflow | Significant |
| 8 | CAI Cairo | North Africa | Overflight surge, slot pressure | Significant |
| 9 | IST Istanbul | Turkey | Asia-Europe overflow absorption | Moderate |
| 10 | DEL Delhi | South Asia | Compounded Pakistan + Gulf detours | Moderate |
Tiers reflect relative footprint within the Q1 2026 window. "Severe" indicates >20% of scheduled operations affected over a multi-day window; "Significant" indicates 10-20%; "Moderate" 5-10%. Tiers are Cirium-style framing applied here for cross-airport comparison.
Cause attribution
Cirium's standard cause categorisation (airline-controllable, weather, ATC, airport infrastructure, airspace event) was applied to the Q1 2026 dataset. The standout feature is the share of disruption attributable to airspace events — historically a small residual category, now the dominant cause of the March 2026 step-up.
Late-February Gulf cascade and adjacent-FIR restrictions. Historically <5% of the cancellation pool.
Late-winter European storm activity, North America winter cycles. In line with Q1 historical norms.
EUROCONTROL noted summer-pattern flow constraints starting earlier than usual in March 2026.
Supply-chain pressure on engine and airframe spares — flagged by IATA in the Dec 2025 outlook.
Runway works at several major airports plus the FAA NOTAM modernization-window absorption.
Regional breakdown — disruption density
| Region | Q1 cancellations | vs Q1 2025 | Dominant cause |
|---|---|---|---|
| Middle East / Gulf | ~52,000 | +~310% | Airspace events |
| Europe | ~58,000 | +~15% | Weather, ATC, detour absorption |
| North America | ~38,000 | ~flat | Weather + NOTAM transition |
| East Asia | ~12,000 | +~8% | Weather, hub congestion |
| South Asia | ~9,000 | +~22% | Pakistan + Gulf compound detour |
| Latin America | ~5,000 | +~12% | Caribbean rerouting (Venezuela CZIB) |
| Africa / Sub-Sahara | ~3,000 | ~flat | Mixed |
Regional numbers are Cirium-style aggregates rounded to nearest thousand. Year-over-year deltas reflect Q1 2026 versus Q1 2025 published baselines.
Q1 2026 vs Q1 2025
Q1 2025 was characterised by Cirium as broadly normal: cancellation rates near the four-year median, weather as dominant cause, no single airspace event of disrupting scale. Q1 2026 inverts that picture.
| Metric | Q1 2025 | Q1 2026 | Delta |
|---|---|---|---|
| Global cancellations | ~123,000 | ~174,000 | +41% |
| March cancellations | ~46,000 | 92,523 | +~101% |
| Single-day peak | ~7,500 | ~18,000 | +140% |
| Passengers impacted (peak two-week) | ~1.6M | ~5M | +~210% |
| Dominant cause | Weather + ATC | Airspace events | Inverted |
| Severe-tier airports (Q1) | 2 (weather) | 3 (Gulf) | Concentration shift |
The most consequential structural change is not the volume — Q1 2025 was already an elevated quarter — but the cause-mix inversion. Airspace events accounted for <5% of Q1 2025's pool; in Q1 2026 they crossed 50% in March. That share has not been previously observed in the Cirium-published series.
Recovery curve
Cirium documented a fast initial recovery curve once Gulf hubs re-established structured transit. The cancellation rate sequence published in the April release was:
| Week | Gulf-hub cancel rate | Status |
|---|---|---|
| Feb 28 – Mar 6 | 45-55% | Crisis |
| Mar 7 – Mar 13 | 30-40% | Severe |
| Mar 14 – Mar 20 | 20-30% | Significant |
| Mar 21 – Mar 27 | 15-22% | Significant |
| Mar 28 – Apr 3 | 10-15% | Moderate |
| Apr 6 onward | <10% | Normalising |
The recovery profile is consistent with Cirium's framing: Gulf hub capacity is sufficiently elastic, given fleet size and crew depth at Emirates / Qatar Airways / Etihad, to reabsorb traffic quickly once airspace structure returns. The DXB drone-impact series in early March temporarily reset the curve, but by mid-April the dataset showed broad normalisation. See UAE security corridor briefing for the structural fix that consolidated the recovery.
Q2 2026 outlook
Gulf normalisation, secondary CZIB extensions
CZIB 2026-03 was extended to R6 by April 24, with subsequent revisions expected. The UAE security corridor structurally improves throughput. EASA CZIB 2026-02 (Iran) remains in force.
European summer ATC pressure
EUROCONTROL flagged unusually early flow constraints in March 2026. Summer peak (early August) traditionally produces the largest ATC-attributable cancellation pool of the year; the 2026 baseline starts higher. See ATC strikes threat page.
Atlantic hurricane season — Caribbean compound risk
NOAA's May 2026 outlook was above-normal. Caribbean rerouting overlaps the Venezuela CZIB envelope; KMIA / KMCO / KFLL triangle absorbs most of the disruption. See tropical cyclones threat page.
Wildfire smoke and convective season
Wildfire smoke from North American and European fire seasons periodically degrades visibility and triggers diversions. See wildfire smoke threat page.
