The Foreign Office confirmed the change in a travel advisory issued on Monday (1 November), which coincided with Argentina reopening to international travellers under strict conditions.
"Argentina has lifted the ban on direct flights to and from the UK," said the FCDO. "Direct flights between Argentina and the UK are scheduled to resume in December."
The FCDO added there were indirect flight options that could be used to connect with the UK, and advised anyone seeking to travel to check with their airline or travel company.
