Qantas’ direct service from Perth to London’s Heathrow Airport has been diverted as tensions in the Middle East continue to escalate and foreign carriers avoid Iranian airspace amid fears Tehran is planning an attack on Israel.
A Qantas spokesman confirmed flight QF9 from Perth to London would now fly via Singapore for refuelling due to the adjusted flight path. The return flight QF10, however, can carry enough fuel and is still flying direct from London to Perth.
