IST vs SAW: which Istanbul airport should I use?
Istanbul: Private Airport Transfer
Should I fly into IST or SAW Istanbul?
IST (Istanbul Airport, European side) is the main hub served by most international and Turkish Airlines flights. SAW (Sabiha Gökçen, Asian side) is the budget/low-cost airport. The two airports are on opposite shores of the Bosphorus — getting between them takes 1.5–2.5 hours. Choose based on which airline serves your route, not geography preference.
The most common Istanbul airport mistake
Travellers arriving in Istanbul for the first time often assume the two airports are interchangeable. They are not. Istanbul Airport (IST) and Sabiha Gökçen Airport (SAW) are on opposite sides of the Bosphorus — the strait that divides Europe and Asia. Getting between them by road takes 1.5–3 hours and crosses the Bosphorus Bridge (or the Fatih Sultan Mehmet bridge), both notorious for severe traffic congestion.
If you book a flight into SAW and a hotel in Sultanahmet, planning to “just take a quick taxi” — that taxi will take 1.5–2 hours minimum, and can easily take 3 hours in rush-hour traffic.
This guide explains what each airport is, how to get from each to the city, and when SAW is actually the better choice.
Istanbul Airport (IST) — the main hub
Location: European side, approximately 40–45km northwest of Sultanahmet (old city).
Opened: 2019. The largest airport in Europe by terminal capacity. It replaced Atatürk Airport, which closed to commercial traffic simultaneously.
Airlines: Turkish Airlines (main hub — domestic and international), Pegasus Airlines (some routes), and most international carriers. If flying Turkish Airlines or a major European carrier, you almost certainly land at IST.
Domestic connections: All Turkish domestic Turkish Airlines flights depart from IST. For flying to Cappadocia (NEV or ASR), Izmir (ADB), Antalya (AYT), or other Turkish cities from Istanbul, IST is the default airport. Check your specific flight — Pegasus and SunExpress domestic routes use either airport.
Getting from IST to the city
Metro M11 — the best option for most travellers. Direct rail link from the airport to Gayrettepe station (45 minutes). At Gayrettepe, connect to the M2 line toward Taksim, Şişhane, or onward connections. The Marmaray under-Bosphorus rail line connects the European side to the Asian side. The Istanbulkart works on all these routes.
HAVAIST buses — multiple routes to different city districts. Useful if you’re heading somewhere not well-served by M11 connections. Journey time varies 45–90 minutes depending on traffic and destination.
Taxi / private transfer — officially metered taxis are available. The journey to Sultanahmet in medium traffic costs approximately 400–600 TRY (20–30 USD at mid-2026 rates). Request the meter or use the BiTaksi / Uber app (which calls an official taxi). Private transfer services offer a fixed rate and meet-and-greet.
Sabiha Gökçen Airport (SAW) — the Asian-side budget hub
Location: Asian side, approximately 50km east of Sultanahmet.
Primary airlines: Pegasus Airlines (main hub), SunExpress, Corendon. Many budget European flights (Wizz Air, Ryanair partners, etc.) land here. If you booked through a budget aggregator and have a cheap fare, check carefully which airport is listed.
Domestic connections: Pegasus domestic routes depart from SAW. If flying with Pegasus to Cappadocia, Izmir, or Antalya, you use SAW — the opposite side of the city from IST. Do not mix up airports when booking domestic connections.
Getting from SAW to the city
There is no direct metro from SAW. Options:
HAVABUS to Kadıköy — the standard public transport route. Bus takes approximately 40–60 minutes to Kadıköy Pier. From Kadıköy, take a ferry or the Marmaray to the European side. Total journey to Sultanahmet is approximately 75–120 minutes.
Metro M4 — from Sabiha Gökçen, buses connect to Kadıköy metro station (M4). Alternatively, from Kurtköy (closest metro station to the airport), take M4 to Kadıköy. Journey time similar to HAVABUS route.
Taxi — to Sultanahmet approximately 500–800 TRY (25–40 USD at mid-2026 rates) from SAW. Significantly more than from IST for roughly the same distance — the route is often through heavy traffic on the Asian side.
Private transfer — worth considering for SAW arrivals with luggage, as the public transport option involves more changes.
Side-by-side comparison
| IST (Istanbul Airport) | SAW (Sabiha Gökçen) | |
|---|---|---|
| Side of city | European | Asian |
| Distance to old city | 40–45km | 50km |
| Metro available | Yes (M11, direct) | No (bus + connecting M4) |
| Transfer time to Sultanahmet | 60–90 min | 90–120 min |
| Main airlines | Turkish Airlines + international | Pegasus + low-cost |
| Domestic connections | All Turkish Airlines routes | Pegasus/SunExpress routes |
| IST ↔ SAW by road | 1.5–3 hours | — |
| Taxi cost to old city | ~400–600 TRY | ~500–800 TRY |
When SAW is actually the better choice
Despite its more complex transit, SAW can make sense when:
- Your budget fare only lands at SAW. If the price difference is significant (100+ EUR), the extra 30–45 minutes of transit is a reasonable trade-off.
- You’re staying on the Asian side. If your hotel is in Kadıköy, Üsküdar, or Bostancı, SAW is closer and more convenient.
- Connecting from a domestic SAW flight. Pegasus domestic routes from SAW mean you can fly back without the cross-city transfer.
- Your itinerary ends on the Asian side. The reverse is also true — if your last activity before departure is in Kadıköy, SAW is the more logical departure airport.
The IST/SAW mix-up: how to avoid it
The most common error is booking return flights at different airports without realising it. For example: flying in with Turkish Airlines (IST) and returning with Pegasus (SAW) without allowing travel time between them.
If you need to transfer between airports on the same trip:
Private transfer IST ↔ SAW — the most reliable option. Fixed price, meets you at arrivals, no navigation required. Allow 2.5 hours minimum; 3 hours in peak traffic periods.
HAVAIST airport bus IST ↔ SAW — public option, approximately 1.5–2 hours. Takes longer but costs approximately 150–200 TRY.
Allow at least 3 hours for any inter-airport transfer — traffic between the two is unpredictable, and the Bosphorus Bridge or tunnels can add significant time.
Practical tips for each airport
IST (Istanbul Airport)
- The airport is massive — budget extra time for immigration queues (non-Schengen, non-Turkish passport holders use a separate line)
- Istanbulkart is available at the airport for metro use; recharge at yellow machines
- Free luggage carts are available in arrivals
- Turkish Lira withdrawal: airport exchange rates are poor; use ATMs once in the city
SAW (Sabiha Gökçen)
- Smaller than IST, generally faster through immigration
- HAVABUS stop is immediately outside arrivals — easy to find
- The bus route can be slow in Istanbul rush-hour traffic (7–9am and 5–8pm)
- Food and shopping options are more limited than IST
Airport facilities comparison
Knowing what to expect at each airport on arrival matters — particularly for late-night or early-morning flights.
Istanbul Airport (IST) facilities
Istanbul Airport is a genuinely impressive facility — vast, modern, and well-designed. The international arrivals hall flows logically from immigration to baggage claim to a well-signed exit area. Key facilities:
SIM cards: Multiple operators (Turkcell, Vodafone TR, Türk Telekom) have booths in arrivals. A prepaid tourist SIM with data for your stay is worth buying on arrival rather than dealing with roaming costs.
Currency exchange: Available at the airport but at below-market rates. Use ATMs for TRY withdrawal (Ziraat Bankası or Garanti ATMs have lower fees than some forex ATMs) or wait until you’re in the city.
Istanbulkart: Available at the metro station within the airport complex. Buy one here to immediately use the M11 metro on arrival.
Transit hotel: Istanbul Airport has an air-side transit hotel (for passengers with connecting flights). Landside hotels are available in the airport complex for those with early departures or late arrivals.
Luggage storage: Available in the arrivals level. Useful if you have time before hotel check-in.
Food and shopping: Extensive — IST is a major hub with the full range of duty-free, restaurants, and major retail brands. Domestic and international terminal food options are comparable.
Sabiha Gökçen (SAW) facilities
SAW is significantly smaller than IST — a much more manageable airport in terms of navigation and queuing.
SIM cards: Available in arrivals, similar operators to IST.
Currency exchange: Same advice as IST — ATMs preferred over exchange counters.
Transport options from SAW: The HAVABUS stop is immediately outside the arrivals hall — easy to find and clearly signposted. Taxis are available at a designated stand. No metro connection directly from the terminal.
Waiting facilities: Smaller selection than IST; sufficient for standard waits.
Late-night and early-morning arrivals
Both airports have 24-hour operation with some service reductions between midnight and 5am.
Late-night IST arrival: Metro M11 runs until approximately midnight. After that, HAVAIST buses (24-hour for some routes) or taxi. At midnight, the M11 is the better option if available; after midnight, arrange a private transfer in advance or use a metered taxi via BiTaksi/Uber.
Late-night SAW arrival: HAVABUS to Kadıköy runs until late evening; check the last bus time before arriving. After the last bus, taxi is the only public option. Private transfer booked in advance is the most reliable solution.
Early departure (5–6am): The M11 from IST starts service from around 5:30–6:00am. Budget arrival: 2.5 hours before international flights; 1.5 hours before domestic. IST immigration queues for non-EU/non-Turkish passport holders can be significant on busy mornings.
Domestic connections from Istanbul
If you’re combining Istanbul with domestic destinations (Cappadocia, Izmir for Ephesus, Antalya, Pamukkale via Denizli), airport choice matters:
Turkish Airlines domestic flights: All from IST. Book at the Istanbul Airport and you need no cross-city transfer.
Pegasus domestics: Primarily from SAW. Check your specific route — some Pegasus routes operate from IST, but the majority are SAW-based.
SunExpress: Primarily SAW.
The critical situation to avoid: Arriving at IST (international flight, Turkish Airlines) and then needing to fly domestically from SAW with Pegasus. This requires 1.5–3 hours of cross-city transfer and is the most common logistics headache for visitors combining Istanbul with a domestic flight. If at all possible, book your domestic connections on Turkish Airlines from IST.
If the domestic portion is from SAW and you’re already staying in Istanbul, depart from your hotel with 3.5–4 hours before your SAW flight in normal traffic conditions; longer during rush hours.

I’m flying with Turkish Airlines — which airport?
IST. Turkish Airlines’ only hub in Istanbul is Istanbul Airport (IST). SAW is not used by Turkish Airlines for international routes.
I booked a cheap Pegasus flight. Which airport?
SAW — Sabiha Gökçen is Pegasus Airlines’ Istanbul hub. Double-check by looking at the airport code in your booking confirmation.
Can I take a train between the airports?
No direct train. Road is the only option — bus (HAVAIST) or private/taxi transfer. Journey time is 1.5–3 hours depending on traffic.
How do I get from SAW to Sultanahmet specifically?
Take HAVABUS to Kadıköy (40–60 minutes), then take the ferry from Kadıköy to Eminönü or Karaköy on the European side (20 minutes), then walk or take tram T1 to Sultanahmet (10 minutes). Total: approximately 90–120 minutes. The Istanbulkart covers all these steps except taxi.
Is it worth paying for a private transfer vs public transport?
For IST: the M11 metro is reliable and cheap — private transfer is optional but not necessary for most travellers. For SAW: if arriving with heavy luggage, travelling after 10pm, or with a group, private transfer saves significant hassle versus the multi-step public route.
