British Airways will from July 14 resume direct flights to Tehran, Iran. The service from Heathrow Terminal 5 will be operated by a four-class Boeing 777.

The route will launch as a six-weekly service before moving to daily flights from winter 2016, giving customers even more choice and flexibility between London and the Middle East.

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."

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.
