More than 5,000 completely empty passenger flights have flown to or from UK airports since 2019, the Guardian can reveal.
A further 35,000 commercial flights have operated almost empty since 2019, with fewer than 10% of seats filled, according to analysis of data from the Civil Aviation Authority (CAA). This makes a total of about 40,000 “ghost flights”.
In one quarter, for example, 62 empty planes left Luton airport for Poland, while in another, Heathrow saw 663 almost empty flights going to and from the US. Both quarters were during the Covid-19 pandemic.

They called the ghost flight revelations “shocking” and said a jet fuel tax was needed and airport expansion plans should be questioned. The UK government describes ghost flights as “environmentally damaging”.

It now includes international arrivals and flights within the UK. The CAA will now publish this data quarterly, as a result of a series of FOI requests by The Guardian.
“Publication of this data is a step in the right
