For eleven straight years, Dubai International Airport (DXB) has called itself the world's busiest hub for international travelers, and it earned that title again in 2025 with a record 95.2 million passengers, up 3.1 percent year on year. Then came the spring of 2026. A regional conflict shut down large parts of UAE airspace for weeks, and DXB's passenger count fell off a cliff at the exact moment its biggest GCC rivals, Abu Dhabi and Saudi Arabia, kept adding capacity.
Most of the regional press reported the DXB drop on its own. Almost none of it put the full GCC picture side by side. DSD built that comparison using UAE regulator (GCAA) statistics, official investor releases from Dubai Airports and Abu Dhabi Airports, and national aviation data from Qatar and Saudi Arabia, to answer the question every founder and investor with Gulf travel exposure actually wants answered: whose airport really grew fastest through 2026, and who is still catching up.
Dubai's Historic Stumble
DXB's crisis began on February 28, 2026, when a strike on the airport injured four staff and forced a temporary halt to operations, the opening moment of a regional conflict that closed off large sections of UAE airspace for weeks. Dubai Airports reported 18.6 million passengers for the first quarter, down 20.6 percent year on year. March alone was far worse: just 2.5 million passengers, a 65.7 percent collapse from the same month in 2025, despite falling during the Eid al-Fitr travel peak.
Dubai Airports had entered the year forecasting 99.5 million passengers for 2026 and a first-ever crossing of the 100 million mark. CEO Paul Griffiths later confirmed that milestone would likely slip to 2027. For background on how the shutdown itself unfolded, see DSD's earlier coverage of the UAE's phased flight resumption.
Abu Dhabi's Quiet Advance
Zayed International Airport (AUH) was exposed to the same regional airspace disruption, yet it entered 2026 from a position of strength. Abu Dhabi Airports closed 2025 with 32.5 million passengers at AUH, up 12.8 percent year on year, naming it the fastest-growing mega airport in Europe, the Middle East and Africa. Fourth-quarter 2025 traffic alone was already running 13.8 percent ahead of the prior year, well before the crisis began.
By the last week of June 2026, once UAE airspace had fully reopened, Abu Dhabi Airports reported average daily traffic at AUH already exceeding the equivalent week in 2025, with more than 93,000 passengers and close to 500 flights a day. In practical terms, Abu Dhabi closed its gap with pre-crisis growth faster than Dubai did.
How Doha and the Saudi Hubs Sailed Through
Hamad International Airport (DOH) in Doha was largely insulated from the disruption. Qatar was not directly drawn into the conflict, and HIA closed 2025 with a record 54.3 million passengers, up 3 percent year on year, with its third quarter the busiest in the airport's history. Doha's 2026 focus has been runway maintenance and service optimisation rather than crisis management.
Saudi Arabia's two largest hubs did more than avoid disruption, they absorbed some of the demand that would otherwise have transited through the UAE. Jeddah's King Abdulaziz International Airport and Riyadh's King Khalid International Airport anchored a national total of 140.9 million passengers in 2025, up 9.6 percent year on year, led by KAIA at 53.5 million and KKIA at 40.8 million, up 8.7 percent. GACA president Abdulaziz Al-Duailej said Saudi carriers operated more than 2,000 extra flights for neighbouring countries between February 28 and May 3, 2026, carrying over 258,000 passengers, traffic that would ordinarily have routed through Dubai or Abu Dhabi.
The Passenger Growth Scorecard
The table below lines up all five hubs on the same basis: full-year 2025 totals and growth, how each fared during the February to May 2026 disruption window, and where recovery stood by early summer. It is the first side-by-side version of this data published in the regional press.
| Hub | 2025 Passengers | 2025 YoY Growth | Feb to May 2026 Disruption Impact | Position by July 2026 |
|---|---|---|---|---|
| DXB (Dubai) | 95.2 million | +3.1% | Q1 down 20.6% to 18.6m; March down 65.7% | Recovering; 100m mark now expected in 2027 |
| AUH (Abu Dhabi) | 32.5 million | +12.8% | Exposed to same airspace closure | Daily traffic above 2025 levels by late June |
| DOH (Doha) | 54.3 million | +3.0% | Largely unaffected, Qatar not embroiled | On track; runway upgrade underway |
| JED (Jeddah / KAIA) | 53.5 million | part of national +9.6% | Unaffected; absorbed diverted flights | Operating at 107% of design capacity |
| RUH (Riyadh / KKIA) | 40.8 million | +8.7% | Unaffected; absorbed diverted flights | New Terminal 2 adds 130% more capacity |
โ Saudi airports carried over 258,000 passengers on more than 2,000 diverted flights during the 10-week disruption window โ AUH daily traffic (93,000-plus) had already overtaken the same week in 2025 by June 30 โ DXB's March 2026 passenger count fell 65.7% year on year, its steepest single-month drop on record โ Hamad International's 2025 total (54.3 million) rose 3% with no crisis-related disruption at all
What Recovery Looks Like Now
The UAE's civil aviation regulator, GCAA, tracked the earliest phase of recovery closely: more than 1.4 million passengers moved through UAE airports between March 1 and 12, 2026, across nearly 7,839 aircraft movements, with national carrier activity back to about 44.6 percent of pre-crisis levels by mid-March. Restrictions were fully lifted by late April, and international carriers began restoring service soon after, including Air France and Turkish Airlines resuming Dubai routes.
By July, DXB's own numbers pointed to a genuine rebound: Dubai Airports expected close to 3 million guests through the terminal in the first half of the month alone, with daily traffic regularly topping 200,000 and July 12 forecast as the single busiest day of the summer. The airport is clearly recovering. The question this data answers is who used the gap to gain ground while it was down.
For any Dubai business that routes staff, freight or investor visits through DXB, the 2026 disruption is a reminder that Gulf air connectivity, long treated as a fixed piece of infrastructure, is not immune to regional shocks. Companies with time-sensitive logistics or frequent GCC travel now have a concrete reason to build in routing flexibility across more than one hub rather than defaulting to Dubai alone.
It is also a competitive signal. Saudi Arabia is not simply recovering alongside Dubai, it is actively investing ahead of demand: Riyadh's new King Khalid Terminal 2 adds 130 percent more capacity, and the future King Salman International Airport is being built with a 40 million passenger target and Riyadh Air as its home carrier. Abu Dhabi, meanwhile, is expanding Zayed International's Terminal A capacity from 45 million toward 65 million. The 2026 disruption briefly narrowed Dubai's lead. Whether that gap reopens depends less on the current recovery than on how these three governments keep investing over the next two years.
โ Dubai remains the largest GCC hub by volume, but 2026 proved its growth curve is not immune to regional shocks โ Abu Dhabi entered the crisis already growing faster than Dubai and used the disruption window to close the gap further โ Saudi Arabia's twin hubs absorbed diverted regional traffic without missing a beat, and are now investing in new capacity ahead of demand
