Generally speaking, there is is far more prestige in being an airline CEO than the boss of a rather obscure airport.
AAB likes the limelight, so unless HE Sheik Halifa Al Thani directs otherwise, he will stay as boss of QR.
What is really sad is that AAB has made, and will destroy, QR.
No smilies in this post. I have a very soft spot for QR and see it still suffering from a misguided CEO gives me no pleasure at all.
