# Where can I find good data on volume of air traffic?

I want to have a look at air traffic fatalities data, and have found good information on number of accidents, like this on AviationSafety.

For comparison I want some (world-wide) data on passenger air traffic volume, like number of flights (journeys) per year, or passenger-km per year. So far I couldn't find it. Some good reference?

For \$799 you can buy IATA's World Air Transport Statistics (WATS)

IATA publish a few summary data values in various reports

Note that I think this is data is only collected from IATA members and much of the data is for western-built jets (figures for other manufacturers are much worse, according to comments in IATA reports)

Passenger Km
Total (International + Domestic)

Rank  Airline                   Millions
1     United Airlines           286,802
2     Delta Air Lines           277,560
3     Emirates                  209,377
4     American Airlines         206,551
5     China Southern Airlines   147,841
6     Southwest Airlines        145,124
7     Lufthansa                 144,236
8     Air France                136,405
9     British Airways           130,129
10    Qantas Airways            110,203


• The 2.97 billion passengers travelled in the last slide – is that a total over several years? Or is that the number for 2012? Mar 31 '15 at 16:49

I think extensive world-wide statistics will be very difficult to compile since it would be spread across so many sources. There are Narrowing it down to Europe and America I think would make it a lot easier...

I did a search with reference to ICAO, the International Civil Aviation Organisation (a branch of the UN), but the data appeared to be behind a paywall. The World Bank however does have data for most countries, again based on ICAO data.

Some nice and detailed data for America appears can be found at the Bureau of Transportation Statics, part of the Department of Transportation.
