I think these changes to the 767 may also cause some consternation on what I call the milk run, the LAX/AKL flights that drop and pick up pax in either RAR or APW and TBU.
Certainly on one of the travel forums there is often complaint by US pax going to RAR about the old 767s, including the lack of lie flat seats for Business class pax. But also economy seating is also mentioned, but the ability to request seat+ (which many were able to do) and in some cases paid for the privilege I have read, has mollified many of them. In fact some of them have booked just because of this. I wonder what will happen when some of them find the reconfigured plane?
