In many cases yes, though it depends on the product and the supplier behind it. Some trips allow a date change for a small difference in fare, while others are sold on terms that do not permit changes once they are confirmed. The rules that apply to your booking are shown before you pay and repeated in your confirmation.
The safest first step is to open your booking through the manage link in your confirmation email and look at the conditions listed there. That tells you whether a change is allowed and what it would involve, so you are not guessing.
If a change is possible, contact our team early rather than close to the travel date. The sooner we hear from you, the more options are usually open, because availability and supplier flexibility both shrink as the departure gets nearer.
