Auckland da Air New Zealand (AKL) para Buenos Aires (EZE) é o O mais longo voo ETOPS que conheço, sob o ETOPS 330. :
Air New Zealand completed the first flight approved for 330-minute extended twin-engine operations (ETOPS), flying a 777-200ER powered by Rolls-Royce Trent 800 engines. The December 1 flight departed from Auckland, New Zealand, and landed in the Argentinian capital Buenos Aires about 12 hours later.
Quanto ao ETOPS 370, não tenho conhecimento de voos regulares comerciais, mas alguns candidatos são Sydney-Joanesburgo e Sydney-Santiago do Chile
