Qantas Airlines.

A Qantas Boeing 737-800 inbound to Perth (PER) on Monday, July 18, announced a mayday after running low on fuel. The jet was in the last stages of a nearly six-hour flight across from Brisbane (BNE) when Perth air traffic controllers put the aircraft into an extended holding time. But with fuel onboard already running low, the pilots made the unusual call of a fuel mayday.
