It is necessary for us to obtain transaction information from you in order to complete your purchase. This includes your name, email address, telephone number, home address and billing information (such as credit card number, card holder name and expiration date). We also request information about your travel preferences. You can choose not to provide information to us, but in general some information about you is requested in order for you to book travel, complete a traveler profile, contact our Customer Support, or initiate other transactions on our site.
