Almost 21 percent of travelers are booking private cars to and from the airports more frequently when compared to three years ago, according to surveys conducted by GO Airport Express, a Chicago-based ground transportation service and GO Airport Shuttle, an international transportation provider. 

Twenty-two percent of 490 respondents say they always (eight percent) or frequently (15 percent) book private cars. Of those who use other means of airport transportation: 38 percent say they sometimes book private cars and 38 percent reply "never."   Forty-nine percent said the amount of times they book private cars has not changed over the past three years.

"Twenty percent is a significant increase and could have a major positive impact on the ground transportation business," says John McCarthy, president, GO Airport Express.  "This tells us that despite the popularity of newer ride-share services, many prefer the convenience of pre-booking airport transportation provided by established companies offering safe, experienced, professionally trained drivers."
