You can request this up to 21 days before your departure by sending us a message via Live Chat. You’ll find details on how to contact us in the ‘Manage My Booking’ section of your booking paperwork.
We'll quote you with a full rundown of the costs so there are no nasty surprises, and our Amendments team will add this to your booking if you're happy to go through with it. You'll then get a confirmation so you know that everything's gone through.
