Several of the world’s giant airlines have changed their flight paths so they wouldn’t fly over the Strait of Hormuz and Gulf of Oman which is controlled by Iran.

Several Malaysian airlines, Qantas of Australia, Lufthansa of Germany, British Airways, and Netherland’s KLM announced that they are planning to designate new paths.

The decisions were made after the U.S Federal Aviation Administration issued an emergency guideline, forbidding American planes flying in Iran-controlled airspace in Strait of Hormuz and the Gulf of Oman.

According to the announcement, at the time when the American drone was shot down, there were many civilian planes flying in the area.

The Federal Aviation Administration expresses concern over the rising tension in the region and announced that the use of missiles by Iran in high traffic airspace was without a warning.

After 2015 when a Malaysian airplane with 289 passengers and crew was shot down in Ukraine, airlines avoid flying over dangerous areas and take more precaution.

This decision by airlines to avoid flying over Iranian airspace comes a few days after President Rouhani’s comments about Iran expanding its transit paths. The decision will impact Iran’s revenue from the transit of foreign flights.
