If you are already booked onto the waiting list for a trip and someone who has a place on the trip is trying to process a name change to you, this is possible, but has to be processed manually by the team.
The automated name change process won't work as you already have a place on the trip, albeit a waiting list place.
What needs to happen is the person with the confirmed trip emails info@nucotravel.com to request this and CC the person on waiting list. We will then confirm that you are both happy to process a name change.
We will cancel the person with a confirmed place, then upgrade your booking from the waiting list to a confirmed booking. This means that the other person would now receive a refund and we would ask you to make payment for your place (if this is after the payment deadline).
