The United States Transportation Department fined Emirates airline $400,000 on Thursday for flights through Iranian airspace during a time of heightened political tension between the US and Iran last year.
Half of the fine will be waived if Emirates avoids similar violations for one year.
The department said the flights carried the code of New York-based JetBlue Airways – a sign that JetBlue could sell seats as if it were a JetBlue plane.
That arrangement made the flights subject to a US ban on flying in Iranian airspace, including areas over the Gulf and the Gulf of Oman.
The Federal Aviation Administration imposed the ban after Iran shot down an American surveillance drone over the Gulf of Oman. The FAA cited political tension with Iran as raising the risk that American civilian planes in the area could be wrongly identified as military planes.
The flights took place over 19 days in July 2019.
In a consent order, Emirates said it does not believe the violation deserves enforcement action but agreed to the fine to settle the matter.
Emirates said after the FAA order it suspended all flights through Iranian airspace except two a day to Tehran. The airline said when it resumed flying planes to and from the US through Iranian airspace, it mistakenly kept JetBlue’s code on the flights.
The airline said it fixed the error and made changes to avoid the same mistake in the future.
The Transportation Department said it viewed Emirates’s violations seriously, and a fine “establishes a strong deterrent against future similar unlawful practices by Emirates and other carriers”.
The risk to civilian planes flying over areas of conflict was highlighted in 2014 when a Malaysia Airlines jet was shot down over an area of Ukraine controlled by pro-Russia rebels. All 298 passengers and crew members on the Amsterdam-to-Kuala Lumpur flight were killed.
Emirates is owned by a state-controlled corporation in the United Arab Emirates and is based in Dubai.
