Jet2 is warning customers that con artists posing as the travel company could try to persuade them to pay for bogus COVID tests and fit-to-fly certificates.

In a Tweet, it warned customers that it doesn’t directly arrange tests or certificates for customers.

It also warned them not to buy ‘any form’ of Jet2 or Jet2holidays credit note via social media, saying they are ‘unlikely to be honoured’.

It added: “You should only book Jet2.com flights or Jet2holidays directly with us or through one of our approved ABTA registered trade partners.”

Meanwhile British Airways’ customers with lost luggage are being targeted by scammers on Twitter.

The Independent newspaper found that fraudsters were contacting those who tweet the airline about missing bags, telling them they need to pay to retrieve them.

A scam Twitter account, @CareBritish, was set up to contact BA customers who sent a tweet to BA’s official Twitter account. It told them they needed to transfer cash to have their luggage redirected to them.

The @CareBritish account has since been suspended.
