As a frequent business traveler, airport transportation is my primary use of Uber/Lyft.

It would be a lot higher percentage if I didn't just use a pre-arranged private car for my home airport. (I live far enough outside the city that Ubers for early-morning pickups, especially for an hour drive into the city, are very thin on the ground.) It would probably also be higher if fewer cities I traveled to had decent transit in from the airports.

But, otherwise, I have pretty much zero reason to use Uber/Lyft/taxis day-to-day.

I spend a few thousand dollars a year on airport transportation but very little of that goes to Uber.
