I have visited all of the PP venues in Miami (MIA). There are two Turkish Airlines lounges, one in Concoruse E and one in Concourse H. I will say the lounge in
Concourse H is much nicer, has a bar, and has better food. If you only have time to visit one of the lounges,
I recommend making the effort to get the one in H. I did a full review of both lounges on my blog with photos and more, see
my review of the Turkish Airlines Lounge (MIA) Concourse H.
