Transport Secretary Grant Shapps has said he wants to drive down the cost of Covid tests required for international travel to resume.
It comes as the government gave more details about how the traffic light system for travel will work, with countries categorised based on risk.
Passengers will have to take Covid tests before leaving and on returning - even from low-risk green countries.
There will be a watch list for those that could go from green to amber.
But the travel industry has expressed concern about the government's testing requirements, warning it could make holidays unaffordable for many travellers.
