IMHO, EWR is superior to JFK, its fast to get to, and CO's C facilities are great.

However, EWR is also very limited in space. There is really no space for a new terminal. Nor is there space for another badly needed runway. We'll see how B does once it is re-done, perhaps they can find more space do expand A properly.

JFK Terminal 2/3 is like a 3rd world country. T4 is great as is the new B6 termianal.
