Advantage issued the first iteration of its safe travel guide in early July, shortly after the government announced the country’s first quarantine-free travel corridors.

However, since then, the travel corridor list has changed markedly, with more than a dozen destinations – including some individual islands – struck off, and several other destinations added.

While the consortium has been updating its guide, it has created a simplified version to help members navigate the current landscape, which also reflects differences between the home nations.

Advantage chief executive Julia Lo Bue-Said said: “With the ongoing changes to the list of travel corridors, we want to ensure our members have all the tools to help them and their clients navigate their way through these utterly confusing quarantine rules and additional Covid-19 entry requirements.

"Previously, the traffic light list which we started producing in July as part of our Covid toolkit contained one single list. However, now that Scotland and Wales have implemented their own quarantine measures on certain destinations – which only adds to the confusion – we have created separate versions for our members in different parts of the UK.

"With seven Greek Islands now being exempt, it is a minefield for travel agents and customers alike to decipher where they can go and what is required of them before they travel, so we hope this helps to provide some clarity during these difficult times.”
