I am writing a report regarding airlines’ key performance.
I got ICAO form thanks it does help but it is not completely detailed.

lets take the BA summary traffic for April 2010.

in 2010 for UK/EUROPE network we have these numbers

– Passenger carried (000) = 1 239 = 1 239 000 pax
– RPK (mill) = 1 293 = 1 293 000 000
– ASK (mill) = 1 860 = 1 860 000 000

by using the definition of ASK :

ASK = Total paying pax boarded for the whole month APR x Distance flown for the whole month apr in UK/EUROP

=> Distance flown = ASK / Total paying pax = 1 860 000 000 / 1 239 000 = 1501,21 km (810.59 Nm)

is that correct ? to short no ? or may be it the average distance of the whole network of UK/EUROPE ?

we can simplify by taking as an example : Company A owning one aircraft of 150 seats and operating on 5 different destination every month 5 flights (each flight stage distance is 100km, 200km, 300km, 400km, 500km) frequency is only one flight per month for each destination

assume total pax carried/month = 1250 pax
seats available/month = 150 x 10 = 1500 seats

The out put are :
5 flights / 10 flights stages
Total distance flown/month = 200 + 400 + 600 + 800 + 1000 = 3000 km

ASK should be = 1500 x 3000 = 4 500 000
RPK = 1250 x 3000 = 3 750 000
PLF = RPK/ASK = 83,33

Is that correct ?

I am steel confused with distances ?

instead of doing this manually, what are the common airline’s tools ?
