Travellers to and from Greece have been warned of potential disruption tomorrow (Thursday) due to strike action.

A 24-hour walkout is planned by public sector unions, including air traffic controllers, in protest over pension reforms.

This may lead to cancelations or delays to domestic flights, according to the Foreign and Commonwealth Office (FCO) in an updated travel advisory.

“Check with your airline or tour operator before travelling for more details,” the FCO said.

“Public services such as hospitals may also be affected.”
