Performance

Your page has 1 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

  • https://assets.moovweb.net/62cf6831-e286-43c0-a4f3-6cfc39630e2f/fc60db92-39df-4686-b640-dcb9aa461688/v48/javascript/rush.js

Optimize CSS Delivery of the following:

  • https://assets.moovweb.net/62cf6831-e286-43c0-a4f3-6cfc39630e2f/fc60db92-39df-4686-b640-dcb9aa461688/v48/stylesheets/.css/main.css

Your page has 3 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

  • http://united.com/
  • https://united.com/
  • https://www.united.com/
  • https://www.united.com/ual/en/us/

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

  • https://rum.moovweb.com/ping (expiration not specified)
  • https://c.go-mpulse.net/api/config.json?key=EQJZ8-V7KGB-S66X9-FBXSR-3A889&d=www.united.com&t=5077638&v=1.500.0&if=&sl=0&si=5cuy0zm0ydhg2e29-NaN&plugins=ConfigOverride,PageParams,IFrameDelay,AutoXHR,SPA,Angular,Backbone,Ember,History,RT,CrossDomain,BW,NavigationTiming,ResourceTiming,Memory,CACHE_RELOAD,Errors,TPAnalytics,UserTiming,LOGN&acao= (5 minutes)

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.

Minify JavaScript for the following resources to reduce their size by 37.6KiB (55% reduction).

  • Minifying https://www.united.com/ual/Format/js/tealeaf/tealeaf.js could save 37KiB (55% reduction) after compression.
  • Minifying https://assets.moovweb.net/62cf6831-e286-43c0-a4f3-6cfc39630e2f/fc60db92-39df-4686-b640-dcb9aa461688/v48/javascript/rush.js could save 660B (51% reduction) after compression.

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

Enable compression for the following resources to reduce their transfer size by 1.2KiB (45% reduction).

  • Compressing https://tag.yieldoptimizer.com/ps/ps?tc=157647070&t=f&p=1020&zcb=9372386175673454&pg=hp&ctry=US&u=598034292.1523291341 could save 479B (48% reduction).
  • Compressing https://www.united.com/ual/en/us/default/home/clientdata could save 372B (47% reduction).
  • Compressing https://downloads.moovweb.com/rum.min.js could save 340B (41% reduction).

Mobile Usability

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

  • The tap target <div id="tile-book-travel" class="tile tile-book…Expand ensTile">Book flight…search options</div> is close to 1 other tap targets final.
  • The tap target <div id="tile-flight-status" class="tile tile-flig…oggler ensTile">Flight status…notifications</div> is close to 2 other tap targets final.
  • The tap target <div id="tile-checkin" class="tile tile-chec…oggler ensTile">Check-in…ge for details</div> is close to 2 other tap targets final.
  • The tap target <div id="tile-mytrips" class="tile tile-mytr…oggler ensTile">My trips…d in a new tab</div> is close to 1 other tap targets final.
  • The tap target <a id="change-language-pos" href="javascript://" class="no-rtad">Currently in…nter to change</a> is close to 2 other tap targets.
  • The tap target <a href="https://www.un…s/default.aspx">Mobile Tools</a> and 6 others are close to other tap targets.
  • The tap target <path> and 4 others are close to other tap targets final.
  • The tap target <a href="#" class="">Canada - English</a> and 4 others are close to other tap targets.

The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.

The page content is 422 CSS pixels wide, but the viewport is only 412 CSS pixels wide. The following elements fall outside the viewport:

  • The element <path> falls outside the viewport.

The text on your page is legible. Learn more about using legible font sizes.

Your page specifies a viewport matching the device's size, which allows it to render properly on all devices. Learn more about configuring viewports.

Your page does not appear to use plugins, which would prevent content from being usable on many platforms. Learn more about the importance of avoiding plugins.
