There should be an online
There should be an online check-in facility for car rentals to save time when picking up cars. Staff always tell me there is no interface between third-party booking agencies such as yourselves, and the supplier. This is nuts, and causes huge delays and queues at airports when pick up a car (60-minute queue at Hertz in Cape Town, for example).
In 2020 there are suppliers still photocopying personal documents, which is shocking in itself in an age of scanners and secure apps.
It's no longer enough to offer a quick and simple booking service, that needs to extend to to the pick up experience.
