I didn't spend much time in the airpot, i was in a smaller terminal and i got there at 4:30am and left around 6:45. So my review may not reflect being there during peak hours.
I had no issues getting through security, no wait at all.
The staff i did speak to were very nice.
There were plenty of places to sit and eat/shop.
i sat down and ordered my food/drink from an iPad at the table which was super continent.
My flight was on time and everything went perfect.
