Am I correct in saying it's only for flights
FROM these countries and not to them?
The latest gov.uk travel advice:
Latest update: Summary – there’s a heightened risk of terrorist attack against aviation; the UK government has decided to implement additional security measures for flights departing to the UK from a number of countries including Egypt in the coming days but no later than 25 March; you should co-operate fully with security officials; if you need more information about how this may affect your flight, contact your airline or travel company
