Virgin Atlantic has joined other airlines in deciding not to fly over Iraq due to safety concerns.
Fears that insurgents could fire rockets at passenger planes have been heightened by the recent downing of flight MH17 in Ukraine.
However some airlines, including British Airways, are continuing to fly over Iraq and have stressed the need for clear guidelines on which routes are safe to fly.
Virgin's decision follows a decisions from aviation chiefs to set up a new task force to ensure information affecting airline safety is effectively collected and distributed.
The mother of the three Australian children killed on flight MH17 told a memorial service her "arms would always be reaching for them."
A woman has apparently posted pictures of herself on social media with mascara looted from the Malaysian Airlines flight MH17 crash site.
A large section of plane wreckage and everyday carry-on items like chocolates remain scattered among the wild flowers at the crash site.
