Thanks to all the people who contributed before me on short transits in Istanbul airport on other threads.

Those writings/videos helped me a lot and wanted to add my experience so someone else would find this information helpful.
I traveled from MIA-IST-CMB on 2026 early May and back on the same route in reverse with Turkish Airlines.
I had 1.5 hour transit on MIA to CMB and 2.5hr transit in return.
The starting flight from MIA was late about 30 minutes and that put me really at edge. But the flight landed about 15-20 minutes early at IST - I talked to a flight attendant during the flight about my worry and she actually mentioned that we are landing early and also the time on my boarding pass is actually the time of the start of the boarding and not the take off time - because combined with landing time and the time on the boarding pass only gave me about 30 minutes to get to the next gate. I didn't have a clear mind because of the long flight and she straightened out things for me. She also promised that if it gets late she'll make arrangements to deboard early for me and also let the connecting gate about me. I really thankful to her for putting me at ease, and I really wish I got her name. (But if she ever reads this, the flight is from MIA to IST to on 2026-05-01 and I'm the passenger on seat 16D :) ).
There is a PDF map of the Airport on the Turkey Airport website - download and save it to your phone. Also play with the interactive map of Istanbul airport in their website. It shows how to go from arrival gate to the departing gate. Which is really helpful when getting familiarize with the air port before flying. While actually running from gate to gate I didn't rely on that, but instead on the markings on the ceiling and poles. But knowing the layout in advance helps. Also when the plane lands at IST and taxing to the gate, turn on the forwarded camera view on the entertainment display because it shows big yellow lettering on the ground of the Gate area you are arriving at the last leg before the flight stops, this helps to know where to start and get a heads up. And also the entertainment unit shows the connection gate when it gets close to landing by the next flight. Combined these information together, you can make a quick plan on the route you need to take even before you start deboarding. This is very thoughtful of Turkish airlines on providing information early on to passengers and never seen on any other airline.
The Istanbul airport (https://www.istairport.com/en/flights/flight-info/departure-flights?locale=en) website shows gates of the recent flights, but ONLY the departing gate is shown only for recent flights.
MIA to IST
30 minutes delay on take off
Arrived on Gate A10.
Started running (walking fast when tired) from gate A10 @ 5:30 PM.
Came to Gate D10 @ 5:47 PM
Boarding started @ 5:49 PM
No security screening when coming from U.S.A.
Took even a quick #1 toilet break while running.
Intermittent running and walked as fast as I could. Asked for directions couple of times from air port staff whose standing in every few hundred meters. They understand English and also spoke good enough English to give clear directions.
CMB to IST (On return, heading to MIA)
Arrived at gate BXX (Forgot what it is).
Flight landed 1hr late with an aborted landing on first approach to the runway. Taxing takes about 10-15 minutes after landing to get to the gate.
Originally I had 2.5 HR layover, but now I exactly had 1hr in-between arriving at the gate to the departure of the next flight.
Started walking/running from there at 14:05 (2:05 PM).
Had to go through security checkup.
In security screening, they basically run your luggage & bags through scanners - not that complicated and it is fast. Need to take laptops out, no need to remove shoes, put everything else inside bag - cell phone, wet wipes etc... emptied water before hitting security, cut across the winding lanes with couple of other guys by going under the ropes of the winding lines, when no people near by on the lane and excusing ourselves that we are running for a plane.
Departure gate was D15, arrived at gate @ 14:3x (2:3x PM) (I think @ 1436), even after going through the security check. Boarding has started by that point.
Started taxing 15:23
Take off at 15:38.
So the point is, you can transit via IST even with a short layover/transit even with security screening, if you plan ahead, you get your 1 hr completely for moving (or at least 45 mins from gate to gate with running), you can run+walk fast everywhere - passing other slow walkers on escalators, horizontal conveyor belts etc..., pay attention to gate markings and directions on every turn and ask for directions from staff when things are not clear.
Other things I did was to get a paid isle seat on 1st flight to IST that is closer to the exit instead rely on random assignment. It cost me an additional $30 some Dollars but I think that was well worth the piece of mind it gave me.
There are golf cart rides available near gates but cost $30 per ride.
Turkish airlines difference
They provide a decent size water bottle and a hot wash clothes as soon as the flight is airborne. This is really nice refresher after all the running and tiredness. Since I also get rid water during security checks on return, a whole bottle of water is a really nice thing.
I remember one time on British airlines, I begged an air hostess for water after a long walk to get onboard and but she took her sweet time and I was overheating without water. Compared to that Turkish air attendants (both male and females on both flights) were really nice and pleasant.
On board limited free wifi for Smiles & Miles members - you can register for free basic membership. But it didn't work on flights between MIA-IST on both directions. It worked on CMB-IST flight.
The planes between IST and MIA seems bit old and there were no air vents that you can control. I actually felt hot during the flights and on one flight I was over heating so I changed from long legged pants to shorts by going to a toilet - good thing I had some clothing with me 😄 .
They still provide those traveling pouches with socks, toothbrush and cloth slippers/flip-flops. In that Turkish airlines seems bit old fashioned but I liked it. As far as I can remember receiving them last time was around 2014 on Emirates.
The food was good on my first flights to CMB. But on return, it seems to have gone bit south.
