The FCO has chartered three British Airways flights to help repatriate stranded tourists, with the first flight due to depart from Lima on Sunday.
A statement said the FCO would also charter domestic flights from Cusco and Arequipa to Lima so that UK nationals can transfer to the London-bound flights.
The move follows an initial British Airways charter flight which returned 172 Britons earlier in the week.

The FCO said it was “in contact with British travellers with the details of the flights so they can take up the offer to return to the UK”.
Foreign secretary Dominic Raab said: “We continue to work around the clock to help British travellers struggling to get back to the UK and thank the Peruvian government for all their support in making this happen.”
British nationals in urgent distress and who need immediate consular assistance can call +442070081500. This number is available 24/7.
