Tail numbers without results


I have four tail numbers in my “my flightaware” area but they have yet to produce any results… N451PA, N452PA, N453PA, N454PA… These are all Polar Air Cargo aircraft that I am certain are in service on a daily basis. Since Polar uses many different flight numbres I though using tails numbres would produce more consistant results… none sofar. :confused:

Was my assumption incorrect? :blush:

BTW, this site is EXCELLENT and I really have no complaints what so ever… just was hoping someone could set me straight regarding the use of tail numbers to track various aircraft.

Thanks for creating such a comprehensive tool!! :exclamation:


When scheduled operators like Polar Air Cargo (and the airlines) fly under flight codes (PACxxx) they never mention their tail number in the flight plan, so we have no way to correlate the two. The only system that knows what flight number matches what tail number is the airline’s internal computer system.
Sorry about that.


There is a way you can find there tail numbers if you have access to acars or a spotters website where acars logs are posted daily.
