Tory backbenchers have reportedly said that there was a growing sense of “horror” over the quarantine measures, which are also in place in Ireland.
A senior Tory told MailOnline that it did not have much support.
He added: “There was a case for it in March, but there isn’t a case for it now.”
Home Secretary Priti Patel’s plans to enforce a mandatory quarantine on all incoming travellers will be discussed in Parliament this week.
Tomorrow, airline and airport bosses will meet with government officials to discuss the quarantine plans.
However, Simon McNamara of the International Air Transport Association (IATA) said that the quarantine rules will “kill travel”.
He told The Times: “All the evidence we have is that this will just kill travel.
“If (governments) persist with quarantine it is effectively the same as locking down your country.”
But travel risk epert Lloyd Figgins, Chairman of the Travel Risk & Incident Prevention (TRIP) said that if the travel industry rushes into a return to travel then it could take the industry even longer to recover.
He exclusively told Express.co.uk: “The key thing here is to reestablish consumer confidence and I think that at the moment the travel industry is really hurting – and I totally get that – but what I would say is that if the travel industry does anything to erode consumer confidence I think they will suffer long into the future.
“But if the travel industry gets this right and adopts robust travel risk management procedures in order to keep people safe during a time of such uncertainty it will secure its future.
“But if it rushes into a return to travel without those appropriate safety measures in place, it will take a very, very long time for it to recover.”
