Negatives - the terminal is an awful long way from the runways, so the taxiing takes an eternity, it needs the Metro line extension
The long walks in the terminal really did me in. I'd add that to the long taxiing as a negative.
True, I'd forgotten about that! It would be nightmare making a connection when you arrive at one end and depart at the other, as there are no moving walkways in the main building, a major flaw for an airport which wants to be considered a major hub airport.
I somehow got the worst possible combination twice. Was flying NUE-IST-ADB and ADB-IST-NUE. The arriving flight from NUE landed on the far west runway. Taxi time was more than 20 minutes and the plane was positioned at the domestic terminal G on the complete opposite side of the airport, despite being an international flight from Germany. So we deboarded by stairs and a bus brought us all the way back to the international arrival terminal (think it was somewhere around B/C). From there I had to walk the whole way back to terminal G, which took quite a long time again, especially as there have been no moving walkways at all. On my return leg more or less same situation: arrival on the far west runway, long taxitime to terminal D gate position, deboarding by stairs and the bus brought us to domestic terminal G and I had to walk back to terminal B for my connection.
The operational processing seems somehow still to be a bit messy, at least from a passenger point of view. On the other hand, the transfer passport and security checks in both directions (intl>dom and dom>intl) have been quite smooth as not too many people have been there. This is so much better than leaving the airside area and changing the terminal at old Atatürk airport, where transfer passengers shared the border control and security checks with departing passengers which sometimes took a ridiculous amount of time. I just don't get, why they require a security check when coming from EU and transferring to domestic. Doesn't Turkey consider the EU as a clean arrival? Or don't they separate the international flights at all and just get all transferring pax through security?
Regardless of some long walking times, I really like the sheer size of the whole terminal. This makes it so much less crowded than Atatürk airport. You'll always find a good seat at your gate, even when a fully booked 77W is waiting at the gate. There are also plugs and USB-ports for every other seat which is really helpful.
The most annoying thing for me was the internet at the airport. It is necessary to register with your phone number to get an access code. This is in my opinion a quite antiquated process but I'm okay with that. What really bothered me is that you have only ONE HOUR of access per day and number. I mean seriously? One hour, when I have a transfer time of four? What they expect me to do in the renaming time? Go shopping? Seriously this is a huge disadvantage for me when I can't even use the internet all the time, because someone thought one hour per person is enough. There isn't even the option to buy more time, I just got the message, that my time is up and I should try later again.
