The Common Travel Area (CTA) is an agreement between the UK and Ireland (including the Isle of Man and the Channel Islands) that allows citizens from either country to travel freely between both without the need for passport checks. You can find more information on this on the link below:
When placing an order, you may be asked for the 'Date on which you will depart from or transit through a country or territory outside the common travel area' (See image below)
This refers to the date you leave your destination country to return to the UK. In most cases, both dates needed in the image above are the same. We ask this so the government can effectively track which countries passengers have passed through before returning to the UK.
The dates you enter here are important as these will determine when your test(s) are delivered. If the information given is incorrect, your test(s) may not arrive for when you need them. If needed, you can amend your flight details from your dashboard. For more information on how to do this, click here
