The travel industry has been vocal in its criticism of the government's quarantine rules, warning that the mandatory two-week isolation period will deter visitors and put jobs at risk.
The manufacturing industry has also highlighted that fewer flights will restrict imports and exports, which will have a knock-on effect for the freight industry, as well as hampering the recovery of some businesses.
British Airways, Easyjet and Ryanair have written to Procurator General Sir Jonathan Jones, the government's most senior legal official - the first stage required when taking legal action against the government.
And travel trade body Abta has called on the government to urgently create a roadmap for restarting international travel.
"We must restart international travel as soon as it is safe to do so, and businesses and customers would benefit from the government outlining when this is likely to happen," said Abta's chief executive, Mark Tanzer.
"There are many livelihoods at stake, and bookings will only start to pick-up in earnest when people and businesses have a better idea as to what the government's plan is to open up the UK and access to international destinations."
The UK's biggest airport services company, Swissport, has also warned that the rules could deliver a "killer blow" to the tourism sector.
Instead, they suggested that the UK agree so-called "air bridges" with countries that have low coronavirus rates, and enable visitors from these countries to enter the UK without having to quarantine for 14 days.
Following this, aviation, maritime and rail industry leaders were invited to a roundtable discussion with the home secretary and aviation minister Kelly Tolhurst on 4 June to discuss the new quarantine plans.
