Heathrow Airport chief executive John Holland-Kaye said the UK’s current travel rules were “still quite complicated” and needed to be simplified to make it easier for people to travel, as well as reducing some of the extra costs.
He told Radio 4’s Today programme: “We need to get rid of the requirement for everyone to have a PCR test and replace it with a simpler, cheaper lateral flow test as a first line of defence.”
He also said opening up travel from the US was a good start for the industry but added “we’re not going to get back to normal” until the US opens its borders to people from the UK.
In a letter to Mr Shapps, the leaders of UK airlines described the change as a “positive step” but said they were concerned that the UK aviation sector was not on the path to recovery “due to the continued restrictions that are being imposed on international travel”.
They wrote that green status should “increasingly become a default” for countries, citing falling case numbers and the proportion of the UK population now vaccinated.
The airline bosses also warned that the UK aviation industry was “facomparedr behind” its European equivalents, with travel bookings at 16% of pre-pandemic levels with 60% in Germany and 48% in France.
International cruises have been allowed from Northern Ireland since Saturday.
