On the screen where a booking is confirmed, you see a button labeled "Price info ⓘ".
Pressing that button displays a breakdown of the fees and how they are calculated.
The fees vary by type of car:
Standard - a normal 4-seat car.
Extra Large - 7 seats
Premium - A luxury car
All fees are 25% higher between 20:00 and 08:00 (8:00 pm and 8:00 am)
If you cancel your ride after you have been matched with a driver for 2 minutes, you may get charged a cancellation fee.
If the Driver has to wait for longer than 2 minutes during a pickup, you pay a waiting fee per minute.
