How are Aer Lingus cookies used?

Cookies are used to assist us in making our website and our emails work more efficiently as well as to provide us with business and marketing information. We use them to remember your preferences, for example what departure airport and language you select when booking a flight. When you leave the site and come back at another time, this information is then already pre-selected for you thereby generally improving your user experience.

We contract with online partners to help manage and optimize our internet business and communications and to help us measure the effectiveness of our advertising and how visitors use our site. To do this, we use cookies provided by our online partners on this site.

By supplementing our records, this information helps us learn things such as what pages are most attractive to our visitors, which of our products most interest our customers, and what kinds of offers our customers like to see. Although our online partner logs the information coming from our site on our behalf, we control how that data may and may not be used.

In addition, we may use e-mail delivery and marketing companies to send e-mails that you have consented to receive. Pixel tags and cookies are used in those e-mails and at our website to help us measure the effectiveness of our advertising and how visitors use our website.
