My first plane: A320… 2hr flight.
My biggest plane: A350… 8hr flight.
My dad tho has been into widdde range of flights… From Caravans to Private (company) Jets and Fokker 100 to A380s… I think I can say he has been into 25+ core models… of 7/8 Airplane manufacturers altogether. Almost all of modern age models of Boeing And Airbus. His company makes him travel a lot, especially in the last few years.
Best part is he doesn’t know the name of even 1 model… He forgets even if u tell him… (I told him A380 and he doesn’t remember that name)… He has NO interest in Airplanes. I keep a track of his flights tho.
