As countries respond to the COVID-19 pandemic, including travel and border restrictions, the U.K. FCO advises British nationals against all but essential international travel.
Any country or area may restrict travel without notice. If you live in the UK and are currently travelling abroad, you are strongly advised to return now, where and while there are still commercial routes available. Many airlines are suspending flights and many airports are closing, preventing flights from leaving.
