The transport secretary, Grant Shapps, has confirmed the ban on overseas travel will end on Monday 17 May.
Despite this advice, Britain’s biggest holiday company is offering holidays to a wide range of amber zone islands from 17 May.
Were the Foreign Office to warn against visiting these places, Tui would not operate and offer full refunds.
Should the trip – whether a flight or holiday – go ahead, there is no automatic entitlement to a refund.
In practice, though, most firms will cancel departures to red list locations, and many will also axe trips to amber list countries as well.
Many people have done something similar via Cairo or Istanbul when they were both on amber and South Africa was red.
But on a very short trip to the UK, you must still book a day-two test, even if you do not take it.
