The grandfathers of many users of this site are still flying on Airbus (as well as all other current planes), so I think you being at least a couple generations to conservative. Instead, I think it's safe to say that the "great-great-grandfathers" of some of the users of this site almost certainly flew on an Airbus. For ease of math, assume an 18 year-old-user born in 2000, 25 years per generation, and a 75 year lifespan. Their father was born in 1975, their grandfather in 1950, their great-grandfather in 1925, and their great-great-grandfather in 1900. That great-great-grandfather died in 1975, and thus assuming they flew in the last years of their life, would likely have flown on an A300. Given that these assumptions might be closer to average rather than extreme, I don't think it would be unreasonable to bet that at least one user's great-great-great-grandfather flew on an Airbus as well.
