Walsh, who runs IAG, the airline group which owns British Airways, said, “It is so much easier for them to go elsewhere. London is losing out because of the visa regime.”
"We understand UK has to have strong borders but you need better systems in place for business people who want to travel here and tourists who want to visit here," he said.
British Airways launched a new route to Chengdu, a strong business region in south central China last year, but fears China is among the Asian countries that face a tough time over visas.
"It is Chinese tourists, particularly, who find it difficult to come to UK," he told the Evening Standard.
"They are still coming and that shows how strong the number of visitors could be, as the Chinese are going through the difficulties of travelling here. But if it was easier we would see a massive increase in tourists from China and that would benefit the economy," Walsh said.
Meanwhile, the capacity of British Airways increased by two percent after the introduction of Airbus A380 and Boeing 787 into the airline’s fleet.
"The new aircrafts' economic and environmental performance has been excellent and customers love them," Walsh said.
