For alt-paxing, this is just the company attempting to avoid scrutiny in the event of a fatigue related incident, while saving money in accommodation and allowances.
It's not actually. There has been a significant amount of discussion within the group that looks at fatigue related issues amongst line pilots and it is still recognised that there is a joint responsibility to ensure a pilot arrives at work as rested and as fit as possible. This discussion has included looking at how other airlines manage commuting, including driving to work.
Alternate Paxing is just one part of the discussion; the main focus is on pilots being
really fit to operate, no matter how they arrive at sign-on, whether its a 4 hour or 12 hour domestic day or a MEL-LAX or PER-LHR.
