Jet2 has urged customers not to respond to requests claiming to be from the Leeds-based airline and asking for personal details.
The company, based at Leeds Bradford Airport, has warned passengers about a series of scams including one relating to Covid testing. Some countries still require visitors to take PCR or lateral flow tests before and sometimes after landing, the Liverpool Echo reports.
The tests are supplied by independent providers and usually have to be purchased separately. On Monday, Jet2 said it did not "arrange PCR tests or Fit to Fly documents" and advised customers: "please do not respond to requests for this".
