Apparently it’s US Airways Magazine, the inflight mag for the airline of the same name, whose June 2007 issue brags it contains Vonnegut’s last interview. Four times.
Even though they did mention it four times, the bragging wasn’t as tacky as it could have been; I suppose if you’re a magazine and you did happen to stumble into a tragedy like this you still have to promote yourself.
But oh man, it couldn’t have been Rolling Stone? Playboy? The New York Times?
