You have to know these guys have earned their right to stay 5.5h out of range with a safety record. A longer flight also means more expensive. There is a calculation showing once you increase the price too much people start taking other less-safe transportation which results in more deaths and more GDP lost in terms of business. While this doesn't directly correlate here with pacific flights, I am sure they've done the same calculation for this case too.
