Crystal Ski is working to repair a technical fault on its website, which has prevented customers from making holiday payments on their accounts and downloading and printing their travel documents.
In the meantime, customers must call Crystal on 020 8939 0726 for assistance.
A spokeswoman said Crystal had been advised by some customers that they were seeing other clients’ travel itineraries when they clicked on a holiday booking link which had been emailed to them. As a result, it had disabled that area of the website to investigage the cause.
She said: "This issue does not affect travel agents’ bookings. They can download and access all information for their customers in the usual way.
"The issue affects direct bookings only and we are contacting all customers who are travelling next week individually to ensure they have the documentation they need.
"We are obviously appreciative of the customers who acted promptly to advise us of the issue.
"We are also urgently taking steps to ensure this situation will not be repeated."
Customers due to travel on December 10 or 13 can request their documents to be sent via email or just present their booking reference number at the airport check in.
Meanwhile, Crystal has launched its first ‘Slope-Ready’ resort for winter 20-17 at Pamporovo in Bulgaria where every booking includes a lift pass, equipment hire and tuition. Prices start at £579 based on two sharing.
