Uber and Lyft are on-demand services, so they cannot guarantee pick up times for scheduled rides. You can't be sure they will show up on time — or at all!
Tempo does it differently. By telling us when you want to be picked up in advance, we can arrange our drivers' schedules so they don't have as much idle time between rides.
This means we can offer higher hourly earnings to drivers AND lower fares to you.
The only catch is that you have to book your ride to the airport ahead of time.
