Qantas will avoid flying over Iran and Iraq airspace until further notice following a series of ballistic missile attacks on Iranian airbases housing American forces.
Nine News understands QF9 from Perth to London and QF10 London to Perth are the only Qantas flights affected by the change.
The altered flights are said to add about 40 to 50 minutes to flying time to QF9.
The changes will also mean Qantas will need to limit passenger numbers on the flight in order to carry more fuel.
Nine News understands flight QF10 will operate with an unchanged passenger load, with prevailing winds leaving flight times unchanged.
Qantas's QF1 and QF2 flights to and from London are unaffected by the changes.
Singapore Airlines said in a statement Wednesday that its flights into and out of Europe have been diverted from Iranian airspace, adding that it is "monitoring the situation closely and will make the appropriate adjustments to our routes if necessary."
Taiwan's EVA Air said that the carrier's European flights began avoiding flying over Iran early Wednesday morning Taiwan time to ensure safety.
Malaysia Airlines said in a statement Wednesday that due to recent events, it "will be avoiding the conflict airspace of Iran."
Both EVA Air and Malaysia Airlines added that they do not fly over Iraq.
In the United States, the Federal Aviation Administration issued a notice restricting non-military US aircraft "from operating in the airspace over Iraq, Iran, and the waters of the Persian Gulf and the Gulf of Oman."
The changes come hours after Iran launched a missile attack on Iraqi airbases housing US forces and a Ukrainian passenger plane crashed shortly after takeoff from Iran's main airport.
The missile strike was in retaliation for the killing of Revolutionary Guard General Qassem Soleimani.
The plane had taken off from Imam Khomeini International Airport in the Iranian capital when a fire struck one of its engines, said Qassem Biniaz, a spokesman for Iran's Road and Transportation Ministry.
The pilot of the aircraft then lost control of the plane, sending it crashing into the ground, Biniaz said, according to the state-run IRNA news agency.
The plane carried 167 passengers and nine crew members from different nations on its flight to the Ukrainian capital, Kyiv, Biniaz said. The crash killed all on board, Iranian emergency officials and Ukraine's Foreign Ministry said.
