How Many Planes In The Air At The Same Time?

Sat May 10, 2008 9:49 am

Did a quick search and could not find this issue discussed before - correct if I am wrong.

I was just wondering how many planes are in the air at certain time point worldwide. And I mean the busiest time of the day and year. Let's say 4 PM central european time when afternoon traffic in Europe is in full action, westbound transatlantic traffic is on its way, morning traffic has started in eastern U.S. and still some action in the far east. Or maybe early morning in europe when more action in the far east and also in the U.S.

Thousands and thousands. I can't remember exactly but IIRC you're talking over 1000 flights over the US alone during the peak periods.


Across the Atlantic you get well in excess of a thousand flights a day.

More like 5000-6000 at peak times in the USA. So if you extrapolate that .. bearing in mind the peak time for Asia, Europe, USA are all different, you probably get 20,000 in the air at one time... maybe?

Even more fascinating... How many of each type are in the air at any onetime?

Boeing used to include the 737 figure in every 737 press release but has stopped that practice - probably became difficult to keep up, but it was in the 1000+ ballpark....

Another question I've pondered.

I wonder when was the last time there was NOT ONE airplane aloft over Earth.
I'm betting it was some time in the late 20s or early 30s. Certainly at no time since WW the Second.

I would say right before the Wright Brother's flight in 1903!  wink

One takes off and lands every 5 seconds...as for how many are in the air, I don't know.

While not a complete list (US IFR flights only), this page at Flightaware is an interesting one:



Especially interesting are the types of which a single example is in the air:



Note the B-25 and Il-96. Yesterday, I noticed NASAs B-52 flying over northern Texas.

Well, right after 9.11 all flights in the US were grounded for at least 2 days if i remember correctly.

On a side note, astronomers were crazy - they could clearly see the difference between a normal nigh sky and a sky free of all the condensation trail left by planes!

Well, to be exact of course, there was never a time when EVERY flight in the US was grounded. Presumably AF1, the military, and various government and emergency flights were airborne at one time or other.

737's average about 8-10 hours per day of utilization and there are about ~4000 serviceable 737's out there. If we go with the low end of the scale to account for planes in maintenance, there should be about 1300 737's in the air at any given time, although it probably goes up and down during the day as different regions hit their heavy flight times.
