No typical airline will have that configuration, those numbers are based upon a 60" pitch in first, and 38" pitch in business. Many typical airlines have more than 70" in business, and call 38" premium economy.

The A330/A340 has always had around a 6000' cabin altitude on long haul flights. They could have gone with VS on the A340-600 to SYD at 6000' for years.
