It’s time to sit back and crunch some numbers using data from our friends at ch-aviation.com. Let’s take a look at the world’s active aircraft to find out which have had the busiest service lives. We shall do so in terms of both flight hours and flight cycles.
Let’s start by examining the rankings as far as flight hours are concerned. Data from ch-aviation shows that the busiest active aircraft by this metric is a Boeing 767-300 freighter belonging to Cargojet Airways. This 33-year old jet (C-FCAE) had racked up a staggering 140,249 flight hours as of April 2021. It previously flew for Canadian Airlines and Air Canada.
