While other international airlines free from the FAA ban have also taken action to temporarily cancel their own Israel flights (including Delta's SkyTeam partners Korean Air, Air France, and KLM), Delta continues to stand in front of the pack; Anderson was very clear about the airline's position on their aircrafts' in-flight positioning:
We will not allow a flight to be dispatched over Iran, Iraq, Syria, Ukraine, Afghanistan or North Korea. We make this decision wholly independent of any geopolitical or regulatory mandate.
Luckily for Delta, this stance does not mean much alteration to their usual routes. The fact that they fly from the US means their destination typically do not require transiting the air space of the active war zones in the Middle East or Asia. Rest assured in the knowledge that those which do, however, will be rerouted through safer skies.
