Twelve people have been sentenced for conspiracy to defraud Thomas Cook of more than £250,000.
Some of the defendants were arrested at Gatwick after boarding a flight to Jamaica in 2008.
At the trial in Kent it was revealed that false credit card details were used to book luxury trips to the Caribbean.
Jurors at Maidstone Crown Court heard that dozens of all-inclusive holidays at five-star resorts had been booked using compromised bank card details between September 2006 and November 2008.
Rachel Allgood, who was described as the ringleader, also admitted to several similar offences against Sainsburys, Medway Council and Tonbridge & Malling Borough Council.
She was sentenced to four-and-a-half years in jail.
Eleven other defendants, across this trial and others earlier this year, received a mix of jail sentences and unpaid work.
