What are cookies?

Cookies are very small text files stored on your hard drive. They uniquely identify your computer and allow us to store profile information, improve website security and help us to customise your website experience. A unique user identity is created which ensures that you are not required to re-enter sign in details as you move throughout the website. Time spent navigating the site is kept to a minimum.

When you visit our website, we may collect and process information about your website usage (e.g. your browsing history and information about your navigation through our website) using "cookies" and other similar technologies.

Web beacons or pixel tags are electronic techniques that allow our website to count the number of visitors to a page or to recognise users by accessing certain cookies.

If you do not want to help us learn how to improve our site, products, offers and marketing strategy, you can "opt-out" of this website analysis tool.

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.
