Heathrow is promoting the idea of a common international standard across all airports and countries to avoid confusion among the travelling public. Speaking on BBC radio’s Today programme this morning, Heathrow’s CEO John Holland-Kaye said

“When we went into this crisis every country had its own set of measures and Public Health England does have screens for when people arrive into this country, but this mismatch of methods really confuses the travelling public. They are worried they have been screened in one country and not in another because they can’t see all the screens, and that’s exactly why we need a common standard a common international standard.”

Defending the late introduction of the technology, Holland-Kaye said that

“We have followed Public Health England’s advice. They have their own set of measures. Now we are working with them to introduce this thermal screening.  It’s not yet government policy, but we are a global hub airport.. and so we need to adopt a common international standard, not just a UK standard.”
