Three 343E more for Air Mauritius with an option for two more
recently announced. I guess they don't worry so much about slower and lower so much as about ETOPS compliance.
There are two orders on LAN's books but I doubt they will ever be built and may have been traded in in the recent A32x order.
Meanwhile 343 owning airlines like AC are adding a few used ones because they can't get their act together on industrial relations.
The real disaster is A345 - ETOPS is killing this one and not slowly either.
