The decision on Thursday (10 September) came just three weeks after Portugal was added to the travel corridor list, opening up late-summer travel to the Algarve – as well as Portugal’s islands.

Madeira and the Azores will, however, remain on the government’s travel corridor list after the government committed to pursuing a more regionalised approach to quarantine, taking the specific circumstances of island destinations into account.

The Foreign Office is advising against all but essential travel to mainland Portugal, but the exemption to both Madeira and the Azores, which they have enjoyed since July.

In a brief statement, Tui confirmed all holidays to Faro departing up to and including 24 September had been cancelled.

"Due to the FCDO’s advice against all but essential travel to mainland Portugal, Tui UK has cancelled all holidays to Faro, Portugal, up to and including Thursday 24 September 2020," said the operator.

"All impacted customers will be notified and offered the option to amend or cancel and receive a full cash refund."

TTG has also approached Jet2.com and Jet2holidays for an update.
