If your Host accepts your change request, your reservation will be updated and you’ll be charged for the extra time. The original total and the new total will be shown before you submit your trip change request.
In most cases, the additional cost will be charged to your original payment method as soon as the Host accepts your trip change request.
For some payment methods, guests will need to submit the additional payment within 48 hours or by their original checkout time, whichever is sooner.
If you submitted a trip change request and your Host hasn’t responded to it, try sending them a message reminding them to review your request.
If your checkout has passed, it’s too late to make a change request. What you can do, though, is send a new trip request to your Host.
