A few years back I was flying to London, and when I got the ticket it was for an Embraer landing in London City Airport. I was excited about the airport as after flying many times to London it was the only one out of the five nearby airports I had never been to, but the aircraft got me nervous: I never heard of Embraer and it was smaller (I thought bigger=safer, maybe that’s still true?) than the usual Airbus and Boeing I was using regularly. Ignorance will do that, I wonder if this (ignorant customers) is still a factor when airlines buy aircrafts.
BTW the airline sadly put me in a different plane to a different airport in the last minute, no reason given.
