As you can easily find that we have this configuration point '/modules/mgnlsupport/virtualUriMappings/travel-exception-mapping@toUri' which has the value as 'forwardredirect:/travel/exception' then if you have another page somewhere for your site, you can easily change the page location from '/travel/exception' to your new one. The working mechanism is described in our official Virtual URI mapping function.
