In light of the coronavirus pandemic the FCO had previously advised against all but essential international travel. It said: "From 4 July, Greece is exempt from the FCO advice against all non-essential international travel. This is not a reciprocal agreement, and Greece has banned UK flights until at least 15 July. The FCO advice has been changed for a number of popular holiday destinations, including France, Spain and Italy. The government has made it clear that the advice could change again if the infection level began to rise once more.
