# How many US airports have 4 or more parallel runways?

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.

• @WilNeumann: I think it will help if you narrow down your definition of "parallel runway". If you look at Bianfable's answer, for example, it includes KDFW (Dallas/Fort Worth International Airport) with runways 13L/31R and 17L/35R which in my opinion are not really "parallel" and runways 13L/31R and 13R/31L which while meeting the mathematical definition of "parallel", are actually on opposite ends of the airport and so don't meet the colloquial interpretation of "parallel" which implies proximity.

• @JörgWMittag Runways 13L/31R and 17L/35R at KDFW are not parallel and have never been counted as parallel runways. I simply listed all runways the airport has (now updated for more clarity). Aug 24, 2019 at 8:35
• That would seem surprising for CLT to be only one of 7 with 3 or more parallels. Even BNA has 3 parallels and has for as long as I can remember (certainly much farther back than 10 years.) ATL and ORD have 5. Aug 24, 2019 at 21:00
• @JörgWMittag At least in the U.S., 'parallel runways' doesn't not imply proximity, other than that they are at the same airport. It just means the number of runways at that airport that are parallel to each other and, thus, can be used for simultaneous flight operations. For example, ATL has 5 parallel runways, so it can do 3 arrivals and 2 departures (or 2 arrivals and 3 departures) at the same time without interference. The runways are spread out enough laterally that they don't interfere with each other's operations. Within a pair, one is used for takeoff and the other for landing. Aug 24, 2019 at 21:06
