It’s a good service but I’d recommend anyone using it to keep comms active as much as possible. I’d booked my pickup from Budapest Airport the night before, chosen a cautious pickup time, received a confirmation email and even though my flight was slightly delayed, I arrived at the gate 2-3 mins after at the arranged pickup time, so thought everything was ok. I couldn’t see anyone to meet me but after a minute my phone rang and the driver asked me to exit the airport and go to one of the bays outside. He seemed disappointed that I’d not responded to any of his messages or calls but I was surprised he’d tried to contact me as I was bang on time and had only just switched my phone out of aeroplane mode. Still polite though. My friend later told me that part of the service was to use WhatsApp to communicate with the driver, which I hadn’t, so my fault, but I just thought I needed to get out in time. Guess I’m a bit old school and thought someone would be there with my name on a bit of paper. So happy to recommend but it’s not for me. I’d rather just get the bus next time and they’re pretty regular.
