Argentina has lifted a ban on direct flights to and from the UK.
Direct services between the south American country and the UK are scheduled to resume in December.
The relaxation of entry restrictions will help access cruises to Antarctica which depart from Ushuaia in Argentina, the most popular gateway for voyages to the White Continent.
The change was disclosed in updated Foreign Office travel advice.
It added: “There are also a number of indirect flights which can be used to connect with the UK.
“Check with your airline or travel company for the latest information.
“You should also check the travel advice for the countries you will be transiting.”
Argentina’s borders re-opened to travellers yesterday (Monday) who meet various requirements, such as being fully vaccinated at least 14 days before arrival and taking a PCR test within 72 days of travelling.
A further PCR test is required between the fifth and seventh day after arriving in the country and inbound travellers must carry medical insurance with comprehensive cover for Covid-19.
But non-resident foreign nationals who are not fully vaccinated cannot enter Argentina for tourism purposes, according to the Foreign Commonwealth and Development Office.
More than 126,000 Britons visited Argentina in 2019 prior to the pandemic.
