British Airways and Air France have announced they intend to discontinue commercial air service to Iran starting in September, the airlines said. The EU-based airlines said they are stopping the commercial flights for business reasons, following US President Donald Trump´s announcement that he plans to re-impose sanctions on Tehran and companies that continue to work there. British Airways, which is owned by the Spanish-registered IAG, said that its London to Tehran service is currently not commercially viable, which is why they will halt the flight. The last BA flight from London to Tehran will be on September 22, while the last inbound flight from Tehran will be on September 23. Air France said that the weak performance of its Paris to Tehran service has caused them to terminate it from September 18. KLM, the group´s Dutch arm, had already announced plans to pull out of Iran. Germany´s Lufthansa said it had no immediate plans to stop flying to Iran, but will monitor developments.
