Istanbul Airport Statistics and Facts (2026): Passengers, Rankings and Cargo
By Anastasia Maisuradze, Istanbul travel writer
Istanbul Airport (IST) handled about 84 million passengers in 2025, more than 66 million of them international, which puts it level with London Heathrow among the two busiest airports in Europe, and no airport on the continent offers more nonstop destinations. This page gathers the key Istanbul Airport statistics from official iGA, DHMI and ACI publications in one place, with a source linked for every figure.

Passenger traffic by year
| Year | Total | International | Domestic |
|---|---|---|---|
| 2024 | ~80 million | 62.9M | 17.1M |
| 2025 | ~84 million | 66.6M | ~17.9M |
Traffic grew by roughly five percent between 2024 and 2025, and the international share, about four passengers in five, is unusually high for a hub of this size. That international weighting is what makes Istanbul a transfer powerhouse rather than a mainly domestic airport. Exact full-year totals are published by iGA and DHMI early in the following year, so the 2025 figures here are the operator's rounded year-end numbers.
How Istanbul Airport ranks in Europe and worldwide
Based on Airports Council International (ACI) data and the OAG Megahubs index, the airport ranks as follows:
- Among Europe's two busiest airports by passenger numbers, neck-and-neck with London Heathrow at roughly 84 million.
- Inside the global top ten by total passengers, and among the top six worldwide for international traffic.
- Europe's number-one airport for direct connectivity, according to ACI.
- Ranked by OAG's 2025 Megahubs index as the most connected airport on the planet by number of routes, and second globally on the connectivity index behind Heathrow.
- Europe's leading cargo airport, and 17th worldwide for freight, up from 47th as recently as 2019.
Cargo: Europe's freight leader
Freight is one of the airport's strongest cards. Around two million tonnes of cargo moved through Istanbul in 2024, the most of any airport in Europe, and the jump from 47th place worldwide in 2019 to 17th is among the fastest in global air freight. The dedicated cargo city on site, one of the largest in the region, is built to keep expanding as capacity grows.
Airlines, destinations and infrastructure
A record 116 passenger airlines connect Istanbul nonstop to 309 direct destinations, rising above 330 once seasonal routes are counted, which is why OAG ranks it first for the sheer number of connections available anywhere. Turkish Airlines runs its global hub here, and that transfer-heavy network is the reason so many long-haul itineraries route through the city.
Physically the airport is built on a vast scale: the terminal covers about 1.4 million square metres, among the largest passenger terminals in the world under one roof. It operates five runways, three of them independent since the triple-runway configuration opened in April 2025, the first such setup in Europe, which lifts peak capacity toward 148 aircraft movements an hour. The site currently handles around 90 million passengers a year and is designed to reach 200 million once all phases are complete.
Records and busiest days
- Busiest single day by flights: 1,707 aircraft movements, on 18 July 2025.
- Busiest single day by passengers: 282,835 travelers, on 2 August 2025.
- Across 2025 the daily average was roughly 231,000 passengers, with international travelers making up about four in five.
Istanbul's two airports
Greater Istanbul is served by two airports, and it helps to keep them separate when reading statistics. Istanbul Airport (IST) on the European side is the main hub covered here. Sabiha Gokcen (SAW) on the Asian side saw about 48 million travelers in 2025 and is dominated by low-cost carriers. Together the pair moved on the order of 132 million passengers over the year, which makes the Istanbul system among the busiest of any city on earth.

Frequently asked questions
How many passengers does Istanbul Airport handle per year?
The airport welcomed roughly 84 million travelers in 2025, over 66 million of them on international flights, up from about 80 million a year earlier. That averages out to around 231,000 people a day.
Is Istanbul Airport the busiest in Europe?
It shares first place with London Heathrow, the two running neck-and-neck at roughly 84 million passengers a year, and the pair trade the lead depending on the reporting period. Istanbul is clearly the continent's number-one airport for direct connectivity, offering more nonstop routes than any rival.
How many destinations and airlines does Istanbul Airport serve?
A record 116 passenger carriers fly nonstop to 309 direct destinations, above 330 with seasonal routes added. OAG's 2025 Megahubs index ranks it first globally for the number of connections on offer.
What is the difference between IST and SAW?
IST is the main Turkish Airlines hub on the European side, with roughly 84 million passengers in 2025. SAW is Sabiha Gokcen on the Asian side, a mainly low-cost field at about 48 million. The two are separate airports with separate statistics, so their figures should never be added together or confused.
What the numbers mean when you fly
Statistics stop being abstract the moment you join a queue. A daily average of 231,000 passengers means the terminal absorbs a mid-sized city every single day, and on record days such as 2 August 2025 the figure climbs past 282,000. In practice, mornings between 6 and 10 and evenings between 17 and 22 carry the heaviest departure waves, and July and August run well above the yearly average. If your trip falls inside those windows, arrive with more buffer than the airline suggests: security and passport control are sized for the average day, not the record one.
The share of international traffic matters too. With about four in five travelers crossing a border, passport control is the pinch point rather than check-in. Turkish and eligible e-passport holders clear faster through the automated gates, while transit passengers can stay airside entirely; our airport guide and overnight layover guide cover both situations step by step.
The same tables help when you book. Tuesday and Wednesday departures sit well below the weekly peak, winter months run 20 to 30 percent quieter than August, and a dawn flight usually clears the airport before the first departure wave builds. Budget travelers comparing Istanbul airports should also check Sabiha Gokcen: the low-cost carriers concentrate there, while long-haul and full-service networks operate almost entirely from IST. Check which airport your ticket actually uses before booking transfers, because the two sit on opposite sides of the city.
