You still haven't provide examples of the deficiencies of Piarco.
The size of JFK or Dulles doesn't make them more or less of an airport. I was just pointing out that major airports can be crap, but that even if they aren't, your typical international arrival sees the same halls, rooms and lines.
I also already said that for the cost, we should have gotten more. But, I ask again, what makes Piarco a cow shed? You don't think it's impressive enough? The function of loading and unloading passengers is not carried out properly? You find the stores charging too much?
