I know that airlines do change the flight-number after fatal accidents (as discussed in this question on aviation stack exchange) and it seems to makes sense because most people would not want to take a flight that has previously crashed.
Recently I was reviewing my travel souvenirs and I found a ticket for a flight AF445 (which previously was AF447, which crashed). I don't remember knowing at the time the relationship between both flights (never cared to look), but I showed it to a friend and mentioned this coincidence and he said: "I would never take such a flight". He argued that it was basically the same flight, same route, origin and destination, flown by the same airline.
This brings my question: How can I (or perhaps, a more superstitious traveler) know if a flight I'm thinking of taking is the afterwards change of one that didn't make it to the destination airport? Is there such a list somewhere? Or I would have to Google each flight on my future travel plan?
