Region of Waterloo International Airport - YKF

Of those 3 vehicles, are they going to one place to pick up people or doing a route to pick up people at their homes. If they are doing a route some people will have a longer travel time. So at this point are they better off taking the shuttle to save $5 vs taking a taxi to go straight to the airport. And this would be for the group that just don't offer a friend to drop them off for some beer later.

Your post has a whole lot of operational assumptions that don't necessarily need to be true. Just as one possible example, you could start the service with 1 vehicle and first-come-first-serve reservations. If someone in Guelph wants to be picked up after you've committed to picking up someone in Waterloo, they could be out of luck. There are all sorts of trade offs you can make that would scale the service to the actual demand that exists.
