The company was set up in 2000 and held a licence to carry 4,790 Atol-protected passengers in the year to the end of September 2025.
Announcing Jetline Travel’s failure, the CAA said customers who are currently overseas would be able to travel home as their "flight remains valid for the return journey". "You are advised to check in with the airline as per the existing flight ticket," it added.
"The CAA is speaking to the service providers for the other elements of your trip to ensure these continue as planned."
But the CAA told customers due to travel from 6 March: "If you have an Atol flight inclusive package booking and have been issued with flight tickets, the flights may be valid for travel and you are advised to check with the airline.
"If the airline confirms you have a valid ticket for travel, you have the option to travel. However, other services have not been paid to the local suppliers and you will be required to re-arrange and pay for these services again. To avoid any issues in resort, you should confirm the cost of all the services in advance of travel where possible."
It confirmed that it is "currently collating information from the company, and we will update this page shortly with instructions for Jetline Travel Ltd Atol protected bookings on how to make a claim".
On Thursday (5 March), TTG reported that Cunard, Princess Cruises, P&O Cruises and Holland America Line bookings made by the Jetline Holidays agency had been cancelled. The brands cited an alleged “breach of contract”.
"Princess Cruises, along with Cunard and Holland America Line, has made the difficult decision to cancel some outstanding bookings made through Jetline Holidays due to its breach of contract," the joint statement read. "All other bookings, including all P&O Cruises bookings, have been transferred to direct bookings."
It’s not clear how Jetline, based in Barnet, north London, is supposed to have breached its contract with Carnival. TTG has approached director Steven Roberts for comment.
In 2023, the agency had a transaction turnover of £28.1 million and an operating profit of £655,000, according to its most recent set of full-year accounts.
In the accounts, Roberts said the business was still in “recovery” from the “disastrous impact of Covid-19”.
“[We] expect this to be the case for the next two to three years in order to replace the assets that were depleted during the pandemic,” he added.
“However, there remains a significant appetite for people to travel abroad and new strategies are being created to exploit and keep abreast of a changing market.”
