It takes 200,000 lbs of fuel and 300mg of caffeine to fly from LAX to SYD. The A350 will never be useful on that city pair.

What about the health problems created by dehydration if pilots can't drink in the cockpit? Does it have a secondary barrier like the A330? I would drive the FAs nuts stepping out for a drink every hour. On the plus side, it will help prevent DVT by walking out of the cockpit every time you need a drink.
