My experience of QF (& BA) F is absolute pampering and nothing is too much trouble. Crew could not be better and all the time I know that the culture of the airlines prioritises safety. I would feel let down by QF if I were flying from ADL, BNE or PER and could not fly QF F for the longer sector (as was the case pre EK & DXB).
BTW I was told that CASA does not permit some suite designs on locally registered aircraft (i.e. doors not allowed). I was also told, by a reliable source, that the doors are there to comply with muslim ideas about women not sleeping in the same room as men who are not their husbands (so not there to attract westerners as a primary reason)
Clearly some like to fly EK and do not care about the lack of a safety culture and are, therefore, happy with the EK tie up. Others find that we do not have the best of the options available. And some things are clearly the worse of hte options e.g. massive decrease in baggage allowance, loss of PE cabin regardles of whether they matter to you personally. So whether you think that the EK deal works for you or not there are clearly things that are not as promised, it just may be that you do not value them as much as some of us. My other unhappiness about the EK deal is the abysmal security sceeening in DXB: that is definitely a loss when compared with SIN or, in the really good days, HKG. So I take my business elsewhere whenever I can.
