The thing is, with the exception of a few people who've read/contributed on this thread, I wouldn't be surprised if there aren't more than a dozen people worldwide who could tell you which airline this happend on.
First, it was not widely publicized. Second, the one news station that did cover it didn't say the airline name AT ALL. Third, the airline has not taken out any ads saying "We make sure you get to see your grandkid die" (sorry, that was very sick humor, Lord, please forgive me for that, and help the pygmies down there in New Guinea, Amen) And fourth, no airline is going to publish it because then they'd have to create an SOP as to what constitutes and emergency that should be waited upon and what does not, and that would start up the lawsuit machine.
So, this, and other "human" actions, taken by airlines that show themesleve to be be caring, will not result in increased revenue for a particular airline. However, it might increase revenue overall for all airlines.
