Jet2holidays does not offer a standard "24-hour cooling-off period" for full refunds. Once a booking is confirmed, the contract is legally binding, and the lead name is responsible for the full cost. If you cancel within 24 hours of booking, you will typically lose your non-refundable deposit, which is usually around £60 per person. However, Jet2's terms state that if there are discrepancies or errors, you must contact them immediately—and no later than within 24 hours of booking—to potentially rectify the issue without heavy penalties. If you cancel a major holiday element or the entire trip, the charges are on a sliding scale: canceling 70+ days before departure results in the loss of deposit, while canceling closer to the date can incur fees up to 100% of the total cost. It is highly recommended to have travel insurance in place at the time of booking to cover unforeseen cancellations.
