Will there be an extension fee even when its via delayed connect flight or other external reasons? February 23, 2022 05:51 Updated Yes, the extension fee will apply until the device is returned. These extra days are subject to extension rental and option fees. Related articles I did not place any extra options when ordering. Is it possible to add on some of the options when I pick up from the airport counter? What happens if I decide to return the device at a different counter?
