IST or SAW: Choosing the Right Istanbul Airport

Istanbul has two international airports on opposite sides of the city, and whether it's IST or SAW that your flight uses matters more than most travellers expect. This guide compares Istanbul Airport (IST) and Sabiha Gökçen (SAW) — size, location, airlines, and what it means to land on one side and need the other, with the journey into the centre covered separately.

Updated 26 July 2026

Two Airports, Two Sides of the City

Istanbul is split by the Bosphorus into a European side and an Asian side, and its two airports sit firmly on opposite banks. Istanbul Airport (IST) is well north of the European-side city centre; Sabiha Gökçen (SAW) is on the Asian side, closer to the Asian-side districts and, in several cases, no further in practice from European-side districts than IST is, once the bridge crossing is factored in.

This isn't a minor detail. Which airport you land at can add or remove a Bosphorus crossing from your journey entirely, and that crossing is the single biggest variable in Istanbul traffic — bridges and the tunnel are the pinch points the whole city funnels through at peak times.

It's also a detail that's easy to overlook when booking flights, since search engines often show both airports simply as 'Istanbul' with little indication of which side of the city each one serves. Knowing this before you book, not after you land, is the single most useful thing this guide can offer.

Istanbul Airport (IST): The European-Side Hub

IST is the newer, larger of the two, built to be Turkish Airlines' main hub and the country's principal gateway for long-haul and international traffic. It operates from a single large terminal, which in practice means most of the international carriers serving Istanbul land here, and it's built to handle very high passenger volumes.

Its location, though, is some distance north of the city — the main hotel districts run from roughly 37 km (Şişli) to 51 km (Sultanahmet) away, and every one of those routes stays on the European side, so there's no bridge toll involved regardless of which district you're headed to.

The scale of the terminal is itself worth knowing about before you land: it's designed around genuinely large passenger numbers, which generally means more walking between the gate and arrivals, and a bigger building to navigate than a smaller regional airport. None of this is a downside exactly, but it's a different experience to a compact terminal, and worth allowing a little extra time for on both arrival and departure.

• Single terminal, built for high international volume
• Turkish Airlines' primary hub
• 37–51 km from the main European-side districts
• All journeys to European-side districts stay on one side — no bridge crossing

Sabiha Gökçen (SAW): The Asian-Side Airport

SAW sits on the Asian side, considerably closer to Asian-side districts like Kadıköy, Maltepe, Pendik and Kartal than IST is to almost anything. It handles a mix of domestic routes, low-cost carriers and a growing number of international ones, and while it's smaller than IST, it isn't a minor regional airport — it's a genuinely busy second hub.

The distances tell the story: Sabiha Gökçen to Kadıköy is around 33 km, to Pendik just 10 km, to Kartal 15 km — all on the same side, no bridge. Reaching European-side districts from SAW, on the other hand, means crossing the Bosphorus: Taksim is 44 km and around 45–70 minutes, Beşiktaş 40 km, Şişli 43 km, all via a bridge or the tunnel.

Being the smaller of the two airports has a genuine practical upside on arrival: shorter walking distances between gate and arrivals in general, and a terminal that's generally easier to navigate quickly if you're travelling light and keen to get moving. It's a reasonable trade against IST's larger scale and broader international network.

Which Airlines Fly Where

As a general pattern, most international long-haul carriers and the bulk of Turkish Airlines' network operate through IST, which is why the majority of visitors arriving from outside Turkey land there. SAW carries a significant share of domestic Turkish routes and a growing list of low-cost and regional international carriers, particularly from Europe.

The practical upshot is that if you're booking a low-cost European flight to Istanbul, there's a reasonable chance it lands at SAW rather than IST, and it's worth confirming before you plan your onward journey — the two airports are not interchangeable in terms of which side of the city they leave you on.

This pattern also affects connecting itineraries: a long-haul flight into IST followed by a domestic leg is often, though not always, a same-airport connection, since IST does carry domestic routes as well as international ones. A low-cost domestic or regional booking, on the other hand, is more likely to route through SAW, so it's worth checking both legs of any multi-flight itinerary land at the same airport before assuming they do.

What Happens During Arrivals at Each Airport?

Both airports follow the same broad arrivals sequence — passport control, baggage reclaim, then customs before the arrivals hall itself — but the scale is different enough to matter. IST's single terminal is built for very high passenger throughput, which generally means a longer walk from the gate to passport control, and passport control itself can take longer simply because more flights are processing through it at any given time.

SAW's terminal is smaller and, in general, quicker to move through end to end, which is one of the few genuine arrival-side advantages of the smaller airport. Neither airport's arrivals process is unusual or difficult by international standards — the difference is really one of scale and volume rather than design.

For anyone being met — whether by a private transfer or someone waiting for you personally — this scale difference is worth mentioning to whoever's meeting you, since 'a few minutes after landing' can mean a noticeably longer wait at IST during a busy arrival bank than at SAW on an average day. Our meet-and-greet guide covers exactly where a driver waits at each airport.

Domestic and Regional Connections

If your trip includes a domestic leg within Turkey, it's worth checking which airport that flight uses before assuming it matches your international arrival. SAW carries a substantial share of domestic Turkish routes and is a natural connection point for regional travel, while IST, despite being primarily an international hub, also operates a meaningful domestic network of its own.

The practical risk is a mismatched connection: landing internationally at one airport with a domestic onward flight booked from the other means a full cross-city journey, including a Bosphorus crossing, between two flights rather than a simple terminal transfer. This is worth catching at the booking stage, since it changes the buffer time you need between flights considerably.

If you do end up with a genuine cross-airport connection, treat it the same way as any other tight itinerary: build in generous time, and consider a pre-booked transfer that tracks both flights rather than relying on a fixed schedule to bridge the gap — see the section below on connecting between the two airports directly.

Close-In Asian-Side Districts Best Reached via SAW

Beyond Kadıköy, there's a cluster of Asian-side districts that sit genuinely close to Sabiha Gökçen — close enough that the airport you land at, rather than the district itself, tends to be the deciding factor in journey time. These are worth knowing about if your hotel or onward stay is in one of them, since the same district reached from IST instead would mean a considerably longer, bridge-crossing journey.

None of these have a comparably short route from IST, since reaching any of them from the European side means crossing the Bosphorus regardless — so for anyone with flexibility in which airport to book, staying in one of these districts is one of the clearer cases where SAW is the better-matched airport.

As with the rest of this guide, these are measured road distances rather than estimates, and they hold regardless of which specific flight or airline you're travelling with, since the road distance itself doesn't change.

• Sabiha Gökçen to Pendik: 10 km, 15–25 minutes
• Sabiha Gökçen to Kartal: 15 km, 15–25 minutes
• Sabiha Gökçen to Maltepe: 22 km, 25–35 minutes
• Sabiha Gökçen to Bostancı: 26 km, 25–40 minutes
• Sabiha Gökçen to Kozyatağı: 26 km, 30–45 minutes
• Sabiha Gökçen to Ümraniye: 34 km, 35–50 minutes
• Sabiha Gökçen to Kavacık: 41 km, 40–65 minutes

How the Choice Changes Your Journey

The clearest way to see the difference is to compare the same destination from both airports. Kadıköy, on the Asian side, is a good example: from SAW it's a same-side 33 km run of 35–50 minutes; from IST it's 53 km and 55–85 minutes, and it crosses the bridge. Taksim works the other way round: from IST it's a same-side 42 km, 50–75 minutes; from SAW it's 44 km but 45–70 minutes via the bridge — similar time despite the shorter same-side airport being further on paper, because the bridge crossing adds its own delay.

The pattern holds generally: whichever airport shares a side with your destination tends to give a shorter, bridge-free journey, even when the raw distance isn't dramatically different. See our specific route pages, such as Istanbul Airport to Taksim and Sabiha Gökçen to Kadıköy, for the exact figures behind each pairing.

It's worth checking this against your own specific district rather than assuming a nearby, better-known one behaves the same way — two districts a few kilometres apart can sit on different sides of a bridge's usefulness depending on exactly where the road crosses.

More Districts Compared: IST or SAW

The same pattern extends further out from the centre. Üsküdar and Ataşehir, both on the Asian side, follow the same logic as Kadıköy above — a shorter, bridge-free run from SAW, and a longer, bridge-crossing one from IST.

These two are worth calling out specifically because they're common bases for travellers wanting a quieter, more residential stay away from the busiest tourist districts, while still being within reach of the centre by ferry or metro. Knowing which airport keeps the journey on one side is genuinely useful here, more so than for a first-time visitor headed straight to Sultanahmet or Taksim.

What Happens When You Land at One Airport but Stay Near the Other?

It happens more often than you'd think: a flight routes through IST because of the airline's network, but the hotel is booked in Kadıköy or Maltepe on the Asian side, or vice versa. In that situation, the journey simply includes the bridge crossing that the 'wrong-side' airport would have avoided — from IST, Kadıköy runs 53 km and 55–85 minutes; from IST to Ataşehir, 58 km and 55–85 minutes, both via the bridge.

This isn't a disaster, but it is worth knowing in advance so the journey time doesn't come as a surprise, and it's exactly the kind of route where a pre-booked private transfer is more useful than working out public transport connections across a crossing you weren't expecting to make.

It's also worth weighing this against the flight choice itself: a marginally less convenient flight time or connection into the 'right' airport can sometimes be worth more, in overall journey time and stress, than a slightly better flight into the airport on the wrong side of your hotel.

Connecting Between IST and SAW

Occasionally travellers need to move between the two airports directly — a connecting itinerary on different tickets, for instance, or picking someone up from one while departing from the other. There's no fast link between them: it's a full road journey across the city, crossing the Bosphorus, and realistically over an hour depending on traffic and time of day.

This is one of the least forgiving journeys in Istanbul if timed badly, since it combines the longest realistic distance in the city with a mandatory bridge crossing. Anyone with a genuinely tight connection between the two airports should build in generous buffer time, or better, book a private transfer at a fixed price agreed before travel, with both flights tracked rather than relying on a fixed schedule.

It's worth treating this specific journey as its own planning task rather than folding it into the general 'airport to hotel' assumptions elsewhere in this guide — the distance, the mandatory crossing, and the fact that both ends are airports with their own security and check-in processes all add up to a journey that deserves more buffer than it usually gets.

Departure Planning From Each Airport

The scale difference between the two airports matters again on departure, not just arrival. IST's larger terminal and higher passenger volume generally mean allowing more time for check-in and security than a smaller airport would need, particularly ahead of an international long-haul flight during a busy period of the day.

SAW, being smaller, is generally quicker to move through at the departure end as well, though this isn't a reason to cut timing close — a smaller terminal can still have a busy queue if several flights are departing around the same time.

Either way, the journey time from your district to the airport is the same distance whether you're arriving or departing, so the route pages and comparisons throughout this guide apply just as well when working backwards from a check-in deadline as they do when planning an arrival.

So Which Should You Choose?

If you have a choice of flights and no fixed hotel booking yet, picking the airport nearer your planned district saves a bridge crossing and, generally, time. If your hotel is already booked, work backwards from its side of the Bosphorus rather than from the airport name alone.

Either way, the airport itself doesn't need to complicate the trip — see our guide to getting from the airport to the city centre for the onward options from both.

If you're still deciding on flights at all, it's worth checking both the airline's typical airport and the specific flight number before booking, since the pattern described in this guide is a general one, not a guarantee for every route or every date.

• Staying in Taksim, Şişli, Beşiktaş or the old city: IST keeps the whole journey on one side
• Staying in Kadıköy, Maltepe, Pendik or Kartal: SAW keeps the whole journey on one side
• Flight only available through the 'wrong' airport for your hotel: budget extra time for the bridge crossing, or book a transfer
• Unsure where to stay yet: see our where to stay in Istanbul guide first
