As I keep saying, until they know where they are allowed to fly, and when they are likely to get an AOC, MAX is unliklely to commit to anything.
Meanwhile, I still dont understand how they can compete with the mainland on cost (nb mainlanders wont pay for expat crews), and Air Macau wont give them any juicy routes. Strategically I think they are screwed. Also, Venetian are casino operators not airline operator, so I doubt that will go very far out of the VIP space.
...and Air Macau still has its head up its own *rse.
Three cheers for Viva's first Tokyo flight by the way....
