List of cookies used on www.aerlingus.com

JSESSIONID and BV_IDS:

The JSESSIONID and BV_IDS cookies are created/sent when a user 'session' is created. When you enter the homepage you are assigned a JSESSIONID cookie and similarly when you enter the booking process you are assigned a BV_IDS cookie. These are of a unique format so that information stored in one context will not be directly visible in another. Each assigned session has an associated timeout so that its resources can be reclaimed. For example, when purchasing a flight and also booking bags, car hire and insurance we will collect a number of articles in a virtual shopping cart and then finalize the shopping by going to the 'Purchase' page. In such a situation, it is vital to keep track of the current state of the users shopping cart, and a session ID is one way to achieve that goal. This cookie expires once you have closed aerlingus.com in your browser.

country:

The 'country' cookie is sent when you select a particular Country from the homepage dropdown. This is stored on your computer so that when you re-visit the website your chosen country homepage is displayed by default, thereby making the page and content displayed relevant to you. This cookie expires 1 year after it is set, unless removed by the user.

homeAirport:

Similar to the 'country' cookie, the 'homeAirport' cookie is sent when you select a particular City from the homepage dropdown. This is stored on your computer so that when you re-visit the website your chosen homepage is displayed by default, thereby making the page and content displayed relevant to you. This cookie expires 1 year after it is set, unless removed by the user.

language:

Again the 'language' cookie is sent when you select a particular language option from the homepage dropdown. This is stored on your computer so that when you re-visit the website your chosen homepage is displayed in your preferred language by default, thereby making the page and content displayed relevant to you. This cookie expires 1 year after it is set, unless removed by the user.

__utma:

This cookie keeps track of the number of times a visitor has been to the site pertaining to the cookie, when their first visit was, and when their last visit occurred. Google Analytics uses the information from this cookie to calculate things like Days and Visits to purchase. This cookie is what’s called a 'persistent' cookie, as in, it is not set to automatically expire unless removed by the user.

'__utmb' and ''utmc':

The B and C cookies are brothers, working together to calculate how long a visit takes. __utmb takes a timestamp of the exact moment in time when a visitor enters a site, while __utmc takes a timestamp of the exact moment in time when a visitor leaves a site. __utmb expires at the end of the session. __utmc waits 30 minutes, and then it expires. You see, __utmc has no way of knowing when a user closes their browser or leaves a website, so it waits 30 minutes for another pageview to happen, and if it doesn’t, it expires.

__utmz:

__utmz keeps track of where the visitor came from, what search engine you used, what link you clicked on, what keyword you used, and where they were in the world when you accessed a website. It expires in 15,768,000 seconds – or, in 6 months. This cookie is how Google Analytics knows to whom and to what source / medium / keyword to assign the credit for a Goal Conversion or an Ecommerce Transaction.

Another web analytics cookie the 's_cc' cookie is set and read by the JavaScript code to determine if cookies are actually enabled on a user's machine. This cookie expires once you have closed aerlingus.com in your browser.

s_cq:
