Jet2 has issued an "urgent customer notice" to holidaymakers using their services.
The budget airline, which is based in Manchester and which now operates from Bristol Airport, has issued the important message to customers warning them of a scam targeting Jet2 passengers.
The message was shared via the airline's official Twitter account, warning customers not to get sucked in, reports the Liverpool Echo.

The notice read: "URGENT CUSTOMER NOTICE.
"We have been made aware of several customers receiving messages advising to contact @jet2helps.com (and/or similar) to discuss bookings and queries.
"These accounts are NOT affiliated to us, so please DO NOT give personal information to them.
"The only official account for http://Jet2.com and Jet2holidays on Twitter is @jet2tweets which is a verified ‘blue tick’ account."
More people are booking holidays with Jet2 and other operators following a major travel update.
Transport Secretary Grant Shapps announced last week that the traffic light system is to be replaced from October 4 by a single, reduced, "red list" of destinations, from where travellers arriving in England will have to quarantine in a Government-supervised hotel.
People who are fully vaccinated will no longer need a pre-departure test before returning from non-red list destinations, and from the end of October they will be able to replace the day two PCR test with a cheaper lateral flow test.
Steve Heapy, chief executive of Jet2.com and Jet2holidays, said bookings had spiked "by more than 250%".
He said Turkey is proving "exceptionally popular", adding: "Thanks to the certainty that yesterday's announcement has given customers, destinations right across the board are selling well, whether it's for late summer sun, winter or next summer.
"As you might expect, half term dates have also seen a surge in bookings for families."
