Sorry - tried to 'reply' to Mattg's recent informative post, but I couldn't get the most relevant part (below) to come across, so copied and pasted below. Chatting with a friend at dinner, we said that Qatar will be at pains to try to restore its reputation (too much $ at stake), will refer to a review of processes and protocols, and then will find someone to blame for not following their procedures. It is good, however, that they have issued a clearer apology for the 'offensive mistreatment' and it would be good ideally if further redress occurs for the passengers affected.
FROM Mattg --- Qatar’s reputation will take a very long time to recover in Australia (and, frankly, the Western world) unless:
(a) it provides a clear explanation of what happened
(b) those responsible are held to account
(c) an unreserved apology is issued
(d) there is an assurance that this can never happen again.
