The Bay Area provides a case study of the effect of transportation network companies on ground transportation to and from airports.

"In the past year, the number of trips by ride-booking services at the Oakland, San Jose and San Francisco airports has skyrocketed," according to an article by Erin Baldassari.
The growth of transportation network companies (TNCs) is obvious at Oakland International Airport: "Ride-booking consumed less than 2 percent of the total ground transportation market, excluding BART, in July last year but had 57 percent of the market by March…"
The growth of TNCs is also obvious at San Francisco International Airport, where their market share has increased from 9 percent to 58 percent between October 2014 and today.
One the flip side of the growth of TNCs, according to Baldassari, is contraction of the taxi business. At all three Bay Rea airports, taxi trips are down 23 percent—even as flights and passengers have increased.
The article details the legislative deals that allow TNCs to operate at each of the airports, as well as ongoing efforts to legislative a level playing field for the competing businesses.
