Can the driver wait for me at arrivals holding a sign with my name on it?
Yes, no problem. If you would like your driver to be waiting at your airport's Arrivals gate to collect you, perhaps with a sign, you just need to send them a message when you reserve your Cabify (see ‘Can I send a message to the driver?).
Try to make the reservation with enough notice to give them time to make the sign. This service has no additional cost, though you will be charged any waiting time past our 5 minute courtesy period.
