Here is your first Forum » Do you have to book Super Shuttle in advance?

Hello,
On your day of travel, you will be assigned a scheduled pick up time that includes a 15-minute window. ... For rides to the airport, shared-ride must be booked at least two hours in advance, to allow for proper traveler grouping. SuperShuttle recommends booking at least 24 hours in advance to ensure timely accommodations.
Thank You.
