Hi Myer!
MadridMan is correct in saying that we require credit card information as a guarantee of any reservation. However, payment of our shuttle service must be in cash direct to driver.
Our reservation form is hosted in a secure server so you should not worry about sending it via the Internet.
This card will not be charged unless you do not show up at the airport on the day and time of reservation without any notice.
However, if you do not feel comfortable about sending credit card information in the Net, you can always call us toll-free from the airport (900 713 583)upon your arrival to Madrid, and we will pick you up as soon as possible.
Please feel free to email us at info@aerocity.com in case you have any doubt or comments about our services.
Enjoy your trip!
