I don't think anyone's questioning BA's safety standards in connection with this song, I think it's the question of taste - or lack of it - that concerns the thread starter. Perhaps he has a point. Wether the song is about wanting to leave on a jet plane, not wanting to leave on a jet plane, not knowing or caring when he'd be back etc etc is perhaps irrelevant. It's the fact that the singer recently died leaving on a jet plane. Thus, to use his song advertising your airline would, in some circles, be considered bad taste. That's all.
