JFK is a bloody 3 rd world ****ty American airport a disaster waiting to happen!
There are many airports similar to the difficulties of JFK in developed countries.
Right on the other side of Manhattan across the Hudson is a very easy approach at Newark. Yet some airlines choose not to go there. If JFK is deemed dangerous why doesn’t the airline just fly into Newark instead. If they choose to fly to JFK they should prepare their pilots properly.
The pilots of most airlines don’t find JFK a big issue as they have the confidence to do what is necessary within the bounds of the safety margins without worrying about getting fired for minor issues. Unless you’ve been a skipper of a certain operator discussed on these forums you can’t appreciate how fear of punishment affects decision making, no matter how experienced or thick-skinned the pilot is.
