If a traveler applied to determined dates but for any reason they have to be changed, you may do that in your chat with the traveler, and they’ll receive a proposal for amendment with the new suggested dates.
In case the trip is already confirmed, all you have to do is click on the button “change dates” located in your chat with them on the platform. The traveler will receive a change of date request, which they can accept or reject. If they reject, the dates of the former trip remain confirmed. If they accept, the former trip with the old dates will be canceled and a new trip will be confirmed with the new chosen dates!
If the trip has already started, it’s only possible to change the departure date (either to leave earlier or to extend the stay).
