British Airways resumes flights to Iran's capital
British Airways is to become the first UK airline in four years to fly directly to Iran following the lifting of some sanctions against Tehran.
BA will fly six times a week between London Heathrow and Tehran, with the first service set to depart London at around 9pm (8pm GMT).
BA first offered flights between London and Tehran in 1946 but ended its service in 2007 as sanctions were imposed on Iran over its nuclear programme.
Another UK-based airline, BMI, continued to offer flights to Iran, but the service ended in 2012.
Iran and Britain, China, France, Germany, Russia and the United States agreed a nuclear deal last year, paving the way for a softening in sanctions and the resumption of flights.
"British Airways has a long history of flying to Iran so we are very excited to be launching our new six times a week service, direct from Heathrow to Tehran," said Sean Doyle, British Airways' head of network and fleet.
"Iran is a fascinating country, full of amazing and surprising places for tourists to visit and discover its sophisticated and ancient culture.
"The recent lifting of sanctions has also effectively allowed Iran to re-open for business and paved the way for commerce to re-connect with Iran's economy," he added.
The service will be operated by four Boeing 777s and will take just under six hours.
