Use of Cookies

Aer Lingus is committed to protecting your personal information and to respecting your privacy. In this Cookie Policy, we explain how and why the Aer Lingus website and mobile app (collectively referred to as "our website") use cookies and other tracking technologies (web beacons, pixels, clear gifs and similar technologies), which we refer to in this policy collectively as "cookies".

Please read this policy in conjunction with our Privacy Statement. By using our website you consent to the use of cookies as described in this policy and in our Privacy Statement.

We may update this policy from time to time to reflect any changes in law or technology.


What are cookies?


Cookies are small text files that are stored in the browser of your device (computer, mobile phone, tablet or similar web enabled device) and that uniquely identify your device. They are put there by us and our third party providers via our website, by the websites that you visit, or by links you open, for example hyperlinks in emails. The information stored in cookies can then be accessed from your device each time you visit our site and we use that information to identify you (as the user of your device) and to collect information about your online activity.

We use cookies to help us to understand how you engage with and navigate our website, such as what pages you visit on our website, and this information allows us to improve our website and to personalise your online experience. We want to provide a user experience that is quick and easy for you while obtaining information that helps us to keep improving our service offering.


Examples of how Aer Lingus uses cookies:

  • To authenticate users and ensure the security of our website.
  • To record your acceptance of our Privacy Statement when you are buying a ticket.
  • To remember your chosen language and country of origin so that when you leave the website and come back another time, this information is pre-selected for you and generally improves your user experience.
  • To better understand your browsing activity on our website including what links you follow.
  • To see the websites you visited before you visit our website which allows us to build up a picture of your interests and tailor our advertising to you on other (third party) websites via our online partners.
  • If you are an AerClub member, we may identify you when you log in and use cookies while you are browsing on our website (and only on our website) to see how you interact with us and how we can improve our loyalty and reward product and service offering to you and all of our AerClub members. These are Aer Lingus session cookies and they expire when you finish your browsing and leave our website. Other than this, we do not use cookies to identify you as an individual.

What purposes does Aer Lingus use cookies for?



These cookies are essential to allow our website to operate and cannot be disabled. They are usually only set in response to actions made by you which amount to a request for services, such as setting your language and country of origin, privacy preferences, logging in or filling in forms. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. These cookies do not store information that identifies you personally (personal data).


These cookies are used by us or by our approved third parties such as Google Analytics, to collect statistical information about how visitors engage with and navigate our website, what websites they have come from, or which pages on our website are most popular. They also allow us to moderate website traffic so that all visitors receive a consistent and reliable service. All of the information these cookies collect is aggregated and anonymous.


Functional cookies may be set by us or by our third-party providers to provide enhanced functionality and personalisation. If you do not allow these cookies then some or all of these services may not function properly.


These are persistent cookies that may be set by us or by our online advertising partners. They identify your browser and device to and allow us to deliver advertising to you on certain other websites based on what you have viewed on, or if you have previously provided us with your email address we might send you an email to remind you about a search or a booking that you did not complete. By allowing these cookies you will experience more targeted and relevant advertising.


How long do cookies remain on my browser?


Session Cookies

These only remain on your browser while you are on our website. For example, to help us remember you are logged in, we set a small session cookie which will automatically log you out after a short period of inactivity, or if you close down your browser. This is to help keep your account safe and secure.

Persistent cookies

These generally expire after 6 months. They record if you have consented to cookies and to remember your chosen language and country of origin. If you have consented to cookies you will be asked to confirm your ongoing consent every six months.

The maximum lifespan of Essential cookies is also 6 months.
