British Airways has voiced interest in reinstating its direct flights to Iran after a hiatus of almost four years. �

"We are very interested in flying to Tehran and we are hopeful that it will form part of BA's network in the very near future," The Telegraph has quoted Willie Welsh, the CEO of British Airways, as saying. �We are actively looking at it as a destination," Walsh said at a Global Airfinance conference in Dublin last week.

A BA spokeswoman said that the airline reviews its route network regularly, �to ensure that we operate to destinations with a strong demand from our customers.�

If the flights are introduced, it is thought that other Heathrow slots will be dropped to make way for the service, which was stopped in 2012.

Following the recent lifting of sanctions against Iran, the country has been witnessing an increased inflow of tourists.

UK operators have revealed that there was increased interest in travelling to Iran in the second half of 2015.

Wild Frontiers, the London-based tour operator which has included Iran amongst its travel catalogues for years, said the current demand to visit the country is "insatiable", The Telegraph added.

Also, the Belgian website La Libre identified Iran as one of the countries with most tourist attractions after surveying specialized publications such as National Geographic, Lonely Planet and Afar.

Iran saw the economic sanctions that had been imposed against it for multiple years lifted in mid-January after a nuclear deal that it had reached with the P5+1 group of countries was officially implemented.

Iran sealed the deal � the Joint Comprehensive Plan of Action (JCPOA) � with the P5+1 last July.� Based on the JCPOA, certain economic sanctions against Iran would be lifted in return for steps by the country to limit certain aspects of its nuclear energy activities.
