Which Istanbul airport serves what, why Nevsehir and Kayseri are not interchangeable, how the domestic baggage allowance really works and what happens when a flight moves.
Turkey is roughly 1,600 kilometres wide from west to east. That figure explains why almost no tour longer than a week is built on roads alone, and why the first decision when designing a programme is not what to visit but which legs go by air. What follows is the map that actually matters, with the details a flight search will not show you: which Istanbul airport serves what, why Nevşehir and Kayseri are not interchangeable, how domestic baggage allowance really works, and what happens when a flight moves by two hours with a group already on the road.
Istanbul has two airports, one on each side of the city, and the difference between them is about ninety minutes of transfer.
Istanbul Airport (IST) sits on the European side, north of Arnavutköy. It is the Turkish Airlines hub and the point through which most intercontinental traffic arrives. The M11 metro line connects it to Gayrettepe in around half an hour, where you change to the M2. To Taksim, counting the walking interchange, the realistic figure is fifty to fifty-five minutes. There is no direct link to Sultanahmet: metro plus tram, with two or three changes, runs to about seventy-five minutes. The Havaist coaches cover eleven routes and take between eighty and a hundred minutes to the historic quarter, depending on the motorway.
Sabiha Gökçen (SAW) is on the Asian side, in Pendik. It is the main base for Pegasus and AJet and carries a large share of low-cost domestic traffic. The M4 line reaches Kadıköy in about fifty-two minutes; heading for the European side, the sensible route is to get off at Ayrılık Çeşmesi and take the Marmaray to Sirkeci, which puts the journey at around an hour and a half. Metro, ferry and tram to Sultanahmet stretches to two or three hours.
The operational consequence is immediate: a group arriving at IST with a hotel in Sultanahmet does not have the same trip as one arriving at SAW. And if the international flight lands at one airport while the domestic flight leaves from the other, the inter-airport transfer crosses the whole city and can swallow half a day. It is the first thing checked before an air schedule is accepted.
Cappadocia has two airports, and the choice is not settled by looking at a map.
| Nevşehir Kapadokya (NAV) | Kayseri Erkilet (ASR) | |
|---|---|---|
| Distance to Göreme | about 40 km, around 40 minutes | about 75-80 km, around 1 h 15 |
| Scheduled routes | Istanbul, and nothing else: Turkish Airlines to IST, AJet to SAW | IST, SAW, İzmir, Antalya and a network of direct European routes |
| Based carriers | none | Pegasus and AJet, plus Turkish Airlines and SunExpress |
| Daily frequencies | few, clustered in specific windows | many, spread across the day |
On paper Nevşehir is the Cappadocia airport: it is closer and saves about thirty-five minutes of road each way. But it only flies to Istanbul, with two carriers and few frequencies. If that departure is cancelled, the next one may be the following day.
Kayseri costs more road time, but it is an international airport with two based carriers, nearly 2.8 million passengers in 2025, and direct flights to İzmir, Antalya and several European cities. That means two very concrete things: there is a same-day plan B if something fails, and the Cappadocia block can end without going back to Istanbul — jumping straight to the Aegean, for instance. For a large group, or a tour continuing to the coast, that flexibility usually outweighs thirty-five minutes of minibus.
Adnan Menderes (ADB), at İzmir, lies about 18 km south of the city and is the natural gateway to the Aegean: Selçuk, and with it Ephesus, is about 75 km away — around an hour — and Kuşadası about 85 km, also around an hour. It is a large airport with both a domestic and an international network.
Çardak (DNZ), at Denizli, is marketed as "the Pamukkale airport" and the misunderstanding is worth clearing up: it sits some 65 km east of Denizli, which leaves the Pamukkale travertines about 70 km and sixty to seventy minutes away by road. It is not an airport at the foot of the monument, and its route network is far thinner than İzmir's. On most tours Pamukkale is reached by road from İzmir or from Cappadocia, not by air.
The destinations that make a long tour possible in two weeks are almost all air-served: Şanlıurfa for Göbeklitepe and Harran, Gaziantep for the Zeugma mosaics, Kars for Ani and Sarıkamış, Trabzon for the Black Sea and Sumela. By road each of them is twelve to eighteen hours from Istanbul; by air, ninety minutes to two hours. Konya is the intermediate case: it is reached by road from Cappadocia in a day, which is why it fits into the long tours without using up an air leg.
Kars is the clearest case. The Kars and Eastern Anatolia programme flies the Istanbul-Kars leg in about two hours. The rail alternative exists and is famous — the Doğu Ekspresi — but it is worth knowing exactly what it is: the scheduled Ankara-Kars train runs daily and takes around twenty-six hours; the Touristic Doğu Ekspresi, the one with two-berth compartments and photo stops, only operates from December to March, with three departures a week in each direction and tickets that sell out early. It fits a themed winter programme, not a seven-day tour.
This is where most money is lost at the check-in desk, and almost always for the same reason.
In Turkey, domestic flights work on a weight-based allowance, and at a considerably lower weight than an intercontinental flight, where a piece-based allowance is the norm. On top of that, the exact figure depends on the fare family: the cheapest low-cost fares may include no hold bag at all, only cabin baggage.
The practical result is that a suitcase which travelled from Latin America to Istanbul without a murmur can become excess baggage on the Istanbul-Cappadocia leg. And here is the variable that really decides the outcome:
When the domestic leg is issued on the same ticket as the international one, the allowance that normally applies is the international one, and the bag is checked through to the final destination. When the domestic leg is bought separately, the domestic desk applies its own rules: you collect the bag, check it in again and pay the excess if there is one.
So when a tour is being built, the question asked before booking the internal flight is not what it costs but how the client's international ticket was issued. A saving of a few euros on the domestic leg can turn into a bag surcharge multiplied by the number of passengers.
The exact allowance figures change often and depend on the carrier and the fare, so they are confirmed at the moment of ticketing rather than assumed.
Not every long leg is solved by flying. There are three situations in which the road is the better option:
At the other extreme, some tours simply do not exist without aircraft. The fifteen-day grand journey chains three fixed air legs — Istanbul to Cappadocia, Ephesus to Şanlıurfa and Trabzon to Istanbul — plus a fourth that is flown or driven depending on the season and the air schedule. Without them the same route would need more than three weeks.
A two-hour schedule change on an internal flight is not an aviation problem: it is a problem for everything else. In a group file, moving a flight forces a chain of revisions:
That is why the critical moment of a tour with internal flights is not the travel day but the forty-eight hours before it, when the airlines adjust their schedules. The response is handled by the office holding the file, through the emergency contact printed on the client's travel documents; assistance and incident-handling terms are set out on the travel agent page.
By air, to Nevşehir (NAV) or Kayseri (ASR), a flight of roughly one to one and a half hours, plus the road transfer to the hotel: about forty minutes from Nevşehir, around an hour and a quarter from Kayseri. By road it is some ten hours, which only makes sense broken into stages with a stop in Ankara, as the ten-day tour does. The seven-day tour with the internal flight included flies to Cappadocia on day four and returns on day six.
Nevşehir if the shortest transfer is the priority and the timing fits. Kayseri if the programme needs room to manoeuvre, if the group is large, or if the trip continues towards the Aegean or Europe without passing through Istanbul again.
It depends on the carrier and the fare, and the domestic allowance is weight-based and lower than the international one. What really decides it is whether the domestic leg is on the same ticket as the international one or on a separate ticket. It is confirmed at ticketing.
The scheduled Ankara-Kars train runs daily and can be reserved; the Touristic Doğu Ekspresi runs only in winter, with three departures a week and two-berth compartments, and is sold through the railway company and authorised agencies. For a group, availability is checked when the quotation is prepared, because seasonal berths sell out a long way ahead.
The number of air legs is what separates a seven-day tour from a fifteen-day one, more than the number of cities. Before choosing the format it is worth reading the comparison of tour lengths; and before fixing dates, the operating calendar, because in bayram weeks domestic flights sell out and rebooking stops being possible. If the programme includes Cappadocia, the timing of the return flight directly governs the second chance at the balloon.
With the itinerary, the dates and the number of travellers we prepare the quotation for the programme, with the air legs inside or outside it, whichever suits the file.
