British Airways is set to resume direct flights to Iran, running six round trip flights per week with more flights scheduled to be added later this year. Some sanctions against Iran were lifted earlier this year as part of the nuclear deal between Iran and world powers. The first direct flight to Tehran in nearly four years is scheduled to leave London's Heathrow Airport at 9.10pm on Thursday (1 September) with arrival the following morning.

Iran is expected to experience a tourism boom. Visitors may be surprised to discover the riches the country has to offer, including ancient ruins, pristine beaches and popular ski resorts. Iran made it on to the top destination lists of major publications such as The Financial Times and The Guardian in 2015 thanks to sights that include 2,500-year-old ruins at Persepolis near Shiraz and 16th-century Islamic architectural gems in Isfahan.
