The short answer
Match the airport to the side of the city you're sleeping on. Staying in Sultanahmet, Taksim or Beşiktaş (European side) — fly into Istanbul Airport (IST). Staying in Kadıköy, Moda or Üsküdar (Asian side) — fly into Sabiha Gökçen (SAW) and save both money and a Bosphorus crossing. Only when the flight into the 'wrong' airport is dramatically cheaper is it worth doing the full door-to-door math — this guide gives you the exact numbers.
IST and SAW at a glance
- Istanbul Airport (IST): European side, about 40-50 km northwest of the centre — Turkey's mega-hub and one of the biggest airports in the world
- Sabiha Gökçen (SAW): Asian side, in Pendik, 30-50 km from most hotel areas — smaller and faster to walk through
- IST: home base of Turkish Airlines plus almost every full-service international carrier
- SAW: home base of Pegasus and AJet, plus many European low-cost airlines
- Gate to exit: allow 15-25 minutes of walking at IST; SAW is compact and usually quicker
- Both run 24/7, with metro, buses, taxis and private transfers available around the clock
Who flies where
If you're on a long-haul or full-service ticket — Turkish Airlines, Lufthansa, British Airways, Emirates and the like — you'll almost certainly land at IST. SAW is where the cheap fares live: it's the base of Pegasus and AJet (Turkish Airlines' low-cost arm), and many European low-cost carriers fly there too. Plenty of European cities are served from both airports, so always price both — just check the arrival code before celebrating a bargain, because a €20 flight saving can disappear into the transfer.
Staying on the European side: transfer prices
The private transfer prices below are fixed per vehicle in euros — not per person — and include meet and greet in the arrivals hall, flight tracking, free waiting time and pay on arrival. Book by WhatsApp; the price you confirm is the price you pay.
- Sultanahmet (old city): from IST 50 km, €52 — from SAW 50 km, €54 plus a Bosphorus crossing
- Taksim: from IST 45 km, €50 — from SAW 50 km, €54
- Beşiktaş: from IST €50 — from SAW €52
- Verdict: IST wins — €2-4 cheaper and no bridge, which is worth 30-60 minutes at rush hour
Staying on the Asian side: transfer prices
- Kadıköy / Moda: from SAW 35 km, €44 — from IST 60 km, €58
- Üsküdar: from SAW 30 km, €42 — from IST €56
- Verdict: SAW wins clearly — €12-14 less per car, up to an hour less driving, and no bridge crossing
Public transport, if you're travelling light
- From IST: M11 metro to Gayrettepe (about 40 minutes), then connect to the M2 line; Havaist airport buses to Taksim and Sultanahmet take 75-120 minutes depending on traffic
- From SAW: the M4 metro runs directly to Kadıköy in roughly an hour; Havabus shuttles serve Taksim and Kadıköy about every 30 minutes
- Both options cost a few euros but involve stairs, transfers and crowds — fine with a backpack, hard work with suitcases or kids
- After a late landing, remember the metro winds down around midnight; a fixed-price transfer costs the same at 3 a.m. as at 3 p.m.
