I actually dealt with this pretty recently when flying Turkish Airlines to Istanbul. The seat map was one of the first things I looked at after booking because I really wanted a window seat for the long-haul. Turkish’s system shows a pretty detailed seat map when you go in to manage your reservation, so you can see exactly where the exit rows, bulkhead seats, and extra-legroom spots are. What I liked was that it let me pick in advance, but for the really premium spots, they do charge a small fee unless you’re flying in business class.
On my trip, I had originally chosen an aisle seat, but later realized I’d be more comfortable by the window. Changing it was pretty easy online, but I’ll admit the website glitched once when I tried to finalize the switch. I ended up calling (877)-764-3622, and honestly, that was the smoothest part of the whole process. The rep walked me through the available seats and locked in my new pick in just a couple of minutes.
So yes—you can definitely see the full layout with the Turkish Airlines seat map and make adjustments, but if anything feels off, that number is the fastest way to book, cancel, or modify.
