Our app currently supports booking a ride for up to 6 people in NYC (and up to 4 people in Chicago and D.C.). When setting your pickup or drop-off location in the app, just tap the - or + button near the top of the screen to indicate how many people are with you (e.g., if traveling with two friends, choose "+2"). You can also tap the "1 Passenger" tab above the place pins to add riders.
You can read more about pricing for extra riders here. Please note, there are no additional costs for +1s on private rides, however if you’re traveling with a large group of 5 or more (possible in NYC only) that requires a larger vehicle, you may be charged a bit extra.
(Note: our app does not currently support different drop-offs for riders traveling together, so just make sure you're all going to the same place!)
