Tui cancellation fee determines the time of the cancellation in relation to the departure date. The costs for cancellations made far in advance usually increase as the travel date gets closer. For package holidays there is usually a modest cancellation fee if you cancel 70 days or more in advance of departure; however, there may be costs of up to 100% of the total booking cost if you cancel closer to the departure date. TUI offers choices for travel insurance that may help cover these expenses in certain situations, as well as comprehensive information on individual cancellation fees in their terms and conditions. For exact pricing information, always check the details of your reservation.
