Use of cookies, web beacons and other similar technologies

United and our service providers collect information by using technologies and methodologies, such as "cookies", tags, web beacons or other similar technologies that enable tracking as you browse our sites. We use these technologies to authenticate you as a user, to remember your preferences for using the site, to present offers that may be of interest and to facilitate transactions, such as flight searches and purchases. We and our service providers also use these tools to analyze use of our sites and our services. We may use this information in the aggregate or combine it with information that we have already collected about you.

Cookie. "Cookies" are small bits of information that are stored on your computer by your web browser. Web beacons or “pixel tags” are small strings of code placed on a web page or in an email message for the purpose of transferring information. Cookies and the other technologies discussed in this section allow us to recognize your preference information, to track your transactions and to facilitate effective website administration.

Cookies help establish a user session and allow our server to provide site users with the appropriate information, advertisements and services. We also use cookies to ensure you obtain the information you request, to authenticate your authority to access the site and to track the usage of our websites in order to improve the site(s) according to our customers’ needs. If you are a registered user on our site and you elect to have the site store your MileagePlus number, the cookie stored on your computer will contain your MileagePlus number.

If you do not want your information to be collected through cookies, you can change the preferences in your particular Internet browser. Some website functionality may not work properly if your browser does not accept cookies. Specifically, if you choose not to accept our cookies and are a registered user, you will not have access to your information, such as your user profile, itineraries, award travel, upgrades and MileagePlus summary information, on this site. Although you cannot log into the site as a registered user if you disable our cookies, you can still purchase on the site by logging in as a “Guest”. Please consult your chosen Internet browser for instructions on how to change your cookie settings.

Local storage objects. We may use Flash Local Storage Objects ("Flash LSOs") to store your preferences and to personalize your visit. Flash LSOs are different from browser cookies because of the amount and type of data stored. Typically, you cannot control, delete or disable the acceptance of Flash LSOs through your web browser. For more information on Flash LSOs or to learn how to manage your settings for Flash LSOs, go to the Adobe Flash Player Help Page, choose “Global Storage Settings Panel“ and follow the instructions. To see the Flash LSOs currently on your computer, choose “Website Storage Settings Panel“ and follow the instructions to review and, if you want, to delete any specific Flash LSO.

Clear GIFs, pixel tags and other technologies. These technologies allow us to recognize your preference information, keep track of your transactions and facilitate effective website administration. Clear GIFs are tiny graphics with a unique identifier, similar in function to cookies. In contrast to cookies, which are stored on your computer’s hard drive, clear GIFs are embedded invisibly on web pages. We and our service providers may use clear GIFs (also known as web beacons, web bugs or pixel tags), in connection with our sites and services to, among other things, track the activities of visitors, help us manage content and compile statistics about usage. We and our service providers may also use clear GIFs in HTML emails sent to you to help us track email response rates, identify when our emails are viewed and track whether our emails are forwarded.

Targeted advertising

We and our service providers use the information that we collect about you to serve advertisements to you on various channels, United and other websites, United and third-party mobile apps and other mediums, social networks and television. We and our service providers may collect the data that we use to determine relevant advertising from the following sources: data collected about you online and through your use of our mobile apps, whether collected directly or automatically through cookies, web beacons and other technologies designed to collect data through mobile apps, third-party sites and engagement with social media when publicly available, and offline. Such data combined or appended from various sources. These advertisements may be about United products and services or products and services of third parties that we think might be of interest to you. United and our service providers may use cookies and web beacons when working with these companies to provide them information regarding your use of the site (whether individually or in the aggregate) to assist them in determining relevant advertising.

In addition, some advertising technology used by United to deliver advertisements may use separate cookies and other tracking technologies. This technology may be delivered via visits to our website, email messages, apps or otherwise. Web beacons on some pages of our site, in conjunction with these advertising cookies and our other cookies, enable the advertising technology to better understand onsite activity in the aggregate, to recognize a browser's cookie when a browser visits this website, other websites or apps, and to learn which advertisements bring users to our site or our apps or otherwise take action.

Third-party ad network providers, advertisers, sponsors and/or traffic measurement services may use cookies, JavaScript, web beacons, clear GIFs, Flash LSOs and other technologies to measure the effectiveness of their ads and to personalize advertising content to you. These third-party cookies and other technologies are governed by each third party's specific privacy policy, and not this Privacy Policy

Third-party ad networks may be members of either the Network Advertising Initiative (“NAI”) or About Ads-Digital Advertising Alliance (“DAI”). If they are members and you do not want to receive targeted advertisements from these third-party ad networks, you may opt out. Information as to member companies, the practices of such third-party ad networks and your choices regarding having information used by these companies and how to opt out, can be found at either: for NAI members or for DAI members. Information on how to opt out of the use of your information by DoubleClick is available at and information on how to opt out of Google Analytics is available at

Opting out of one or more NAI or DAI members means that only those particular members will no longer deliver targeted content or ads to you. It does not mean you will no longer receive any targeted content or ads on our websites or other non-United websites. If your browser is configured to reject cookies when you visit one of the above referenced opt-out pages and then you erase your cookies, use a different computer or change web browsers, your NAI or DAI opt-out may no longer be active.


We also use automated devices and applications, such as Google Analytics, to evaluate the use of our websites and apps and the services we provide. We use these tools to gather information about users to help us improve our services, performance and user experiences. These analytics providers may use cookies and other technologies to perform their services, and may combine the information that they collect about you on our websites with other information that they have collected. This Privacy Policy does not cover such third parties’ use of the data.

Your legal rights

In terms of applicable law, you have the following rights regarding the personal data we obtain and process from you (“ARCO Rights”):

  • Access – You have the right to know what personal data we process, what it is used for and the conditions of use thereof.
  • Rectification – You have the right to request the rectification of your personal data in the event that it is inaccurate, incomplete or outdated.
  • Cancellation – You have the right to request that your personal data is removed from our databases when you consider that it is not being used properly.

We may ask you for additional information to confirm your identity and for security purposes. We may not always be able to fully address your request, for example if it would impact the duty of confidentiality we owe to others, or if we are legally entitled to deal with the request in a different way.

Protecting information collected

United maintains physical, administrative, electronic and procedural safeguards to protect your information. When you place orders online to purchase services or access your MileagePlus account information, we use secure servers to protect your personal information, which is intended to encrypt the personal information that is transmitted between you and our sites. Although United takes reasonable steps to safeguard and to prevent unauthorized access to your personal information, it cannot be responsible for the acts of those who gain unauthorized access and United makes no warranty, express, implied, or otherwise, that we will prevent unauthorized access to your personal information.

If a third party seeks to transact business with United on your behalf, that party will be asked to provide us with the same personal information we would collect directly from you to complete your transaction. Unless and until we are advised otherwise, we consider that such third party has an appropriate legal basis to provide us with your personal information and make such transactions and any subsequent changes, on your behalf in accordance with this Privacy Policy. If such third party who has your full name and booking reference contacts us and seeks information on your booking or requests changes to it, we will disclose your booking information and allow such third party to make changes as we will conclude that third party has an appropriate legal basis to do so. Please note that the collection, use and disclosure of your personal information by a third party is subject to your dealings with them and, if applicable, any of their privacy policies and practices. If you do not want an individual to obtain information on or make changes to your booking, you should not share your booking reference with them.

Your role in protecting your information

To protect your privacy and United's proprietary databases and systems, you should not share any of your information, such as MileagePlus number or password, with any unauthorized individuals or third-party information aggregators that would allow them access to your sensitive account information. For more information, see our PIN/Password Frequently Asked Questions page. You should also take all necessary steps to secure your mobile devices and protect information you may have stored on them. We do not have control over the security of your mobile device. United assumes no responsibility for the loss of information associated with security disrupting technologies, reverse engineering of mobile device applications or malware, that compromise the United mobile application(s) as a result of owner or third-party initiated changes to the mobile device. The security of that mobile device is the responsibility of its owner, not United.

Changing your marketing preferences

MileagePlus members can opt out of receiving marketing or promotion-related emails, phone calls or direct mail from United by accessing their account profile information on the United website and changing their profile to indicate their desire to be excluded. In addition, members can contact the MileagePlus Service Center by phone or in writing and request a profile change. Emails sent to members will contain a message and link on how to opt out of that type of communication in the future. Regardless of your opt-out preferences, we reserve the right to send you emails or other communications for administrative purposes.

Location of your information/Data transmittal and transfer/Notice to non-US persons

United will transmit, transfer, store and process information that we collect about you, as described in this Privacy Policy, in the United States, which may not provide the same level of protection for your personal information as your home country. In addition, we may further transmit or transfer your information outside the United States for the purposes described in this Privacy Policy.

Other sites/digital channels

Our sites and our online services may contain links to third-party sites. Any access to and use of such linked sites is not governed by this Privacy Policy but instead is governed by the privacy policies of those third-party sites.
