Boeing stands to lose billions of dollars in sales due to the sanctions on Iran President Trump just announced. In fact, Boeing had been preparing to put the brakes on the Iran sales even before Tuesday's announcement. Boeing has deals to sell 80 aircraft to Iran Air and an additional 30 jets to Iran Aseman Airlines. So investors have had plenty of reason to doubt that Boeing's Iran sales would go through. But even if European countries do not impose sanctions on Iran, those Airbus sales to Iran could be blocked by US sanctions anyway, since Airbus has a US plant and its jets use US-made parts.
