To play Devils advocate
I guess Qantas would fly more than 600 flights a day.
600 x $60 in extra fuel burn = $36000 a day x 365 days = $13,140,000 a year in extra fuel burn
Now it depends on if you are paying the bill or flying the aircraft how that affects you
Now if we were to put in fully capable ILS or GLS even at most big airports maybe that would be a cheaper solution in the long run.
