British Airways is resuming direct flights to Tehran this summer after a gap of four years.
Flights will start on July 14.
The route will launch as a six-per-week service before moving to daily flights from winter 2016.
The service from Heathrow Terminal 5 will be operated by a four-class B777.
Neil Cottrell, British Airways’ head of network planning, said: “Iran is a large and growing economy and Tehran is a brilliant business city so we are incredibly excited to be adding another gateway to the Middle East for our customers.”
British Airways first flew between London and the Iranian capital in 1946.
Tehran is one of 14 new routes British Airways will be launching this year, which include San Jose, Costa Rica, San Jose, California and Lima in Peru.
Return fares start from £384 for World Traveller, £728 for World Traveller Plus, £2163 for Club World and £3763 for First.
Until February 24, Club World fares will start from £1863 return.
