Do you want the long or the short answer?
The long answer - it really would depend what time of the day it is in major geographical regions such as Europe, east coast US, what day of the week, what season (i.e. winter or summer). These are just a couple of factors one has to incorporate.

I was with an airline buff over this past new years and we looked up how many planes were in the air at 11:00 pm on the 31st of dec (he has certain software that shows this) and there were a matter of only a few hundred which he said was extemely low for any time of the night or day.

Those who are really interested in this may want to check out Flight Explorer (http://www.flightexplorer.com). They offer a personal version of their aircraft situation display software, which allows you to view a customizable map showing every plane in the U.S. as well as most international flights coming to or from the U.S. that are over the Atlantic or Pacific. You can also add filters so that the program only displays planes that meet certain criteria. For instance, you could view only 777s travelling to or from JFK. It really is a neat program, but it isn't incredibly cheap (something like $10/month for 10 hours of use and $2-$3 for each additional hour).

Five years ago, more than 4,000 flights a day were controlled by En-route facility in Paris vicinity (Athis-Mons ATC centre). This number is for sure higher now....And that's only for flights flying over Paris...
