Which airports in the US have four or more parallel runways?
How many are planning additions in the next 5 years?
A few years back, 10 years, Charlotte opened their 3rd parallel runway and it was said to be only one in seven in the country. Just wondered if there is an updated number for 4+ runways. I have searched and some sites have great information but I am not sure it is up to date. Not trying to offput just looking for information that might not be posted to the public.
