It said some customers had received messages asking them to contact a fake Jet2 account on social media about their bookings.
It told customers the accounts were fake and urged passengers not to give out personal information to them.
The Jet2 notice on Twitter said: "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."
The warning comes as more people book 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.
Travellers arriving in England from countries on the 'red list' 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.
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%' following the Government's announcement.
He said: "People are clearly desperate to get away for some summer sun, as the demand for holidays in the next few weeks and half-term has been huge.
"Turkey is proving exceptionally popular, and we’re very excited to be flying holidaymakers there from Thursday, September 23."
