But QF is sticking on surcharges of AUD25 to AUG80 per sector; CX is charging +/-USD50, LA USD25-40, so a D/AONE4+ might have - what - 15 segments on surcharging airlines? Plus landing fees, war charges, etc. - it could certainly add several hundred dollars to the bottom line. (Also noted that fuel charges are added by "sector" - not "segment." Don't know if that makes any difference in this case but I suppose it could.)
Having also done a DONE4 ex-IST last year I would also have to question the US$300 figure. Ours were more like $500-$600.
