So how / why does Qantas do it on Aust - US and why did they drop SF and go to Texas which is even longer ?
'Cause its done in a 747-400ER.
Qantas management thinking was to maximise capacity as they cannot increase frequency as both LAX/SFO/SYD are all capacity limited airports. This was their logic in not purchasing the 777.
Whether this strategy has worked given the amount of problems the A380 has had is somewhat questionable.
