Quickest to load... Wego travel portal
Wego is now, fastest loading mobile travel site

Singapore, April 12, 2017: Leading  travel marketplace in the Middle East and Asia Pacific -- Wego.com -- has become the fastest loading mobile travel site in the world.
This is a result of implementing Accelerated Mobile Pages (AMP) combined with Progressive Web App (PWA).
The speed outranks  other global travel sites with a score of 90, where others  have a median score of 51.  Google experience is that40 percent of consumers will leave a site if a page takes longer than three seconds to load on mobile, with 79 percent unlikely to return.
Says Honey Mittal, Wego’s Senior Vice President, Product: “By rebuilding the static pages using AMP, and the core search experience with PWA, Wego has decreased page load time from around 12 seconds to between 0.50 and three seconds.  Over 70 percent of Wego’s searches take place on mobile and increasing site speed was key to upgrading the user experience, and ultimately increasing engagement and conversions.”
Wego implemented AMP on the site’s landing pages which reduced page load time to less than one second when served from the AMP Cache. AMP is a Google project designed as an open standard for publishers to support fast page loads on mobile devices, serving from the AMP cache - a proxy-based content delivery network which delivers all valid AMP documents. AMP uses a stripped down version of HTML and an off-the-shelf Javascript library (blocking third party scripts) that allow lazy loading.
For the search and shop experience, Wego built a PWA using service workers, reducing page load time to less than three seconds for new users, and less than a second for returning users. Progressive Web Apps (PWA) are mobile websites that deliver app-like experiences with full web reach. PWA’s use service workers that are client side proxies produced in Javascript to allow you control over the cache. By pre-caching key resources using service workers, Wego’s PWA is able to deliver content fast and reliably over a variety of problematic network conditions with all testing conducted on a slow, 3G network. Wego’s PWA now supports silky smooth animations with no janky scrolling.  and testing was conducted on a slow 3G network.
“Slow mobile page loads are intensely frustrating, especially during the travel shopping journey,”  Mittal adds, “Wego’s website now opens seamlessly, loading in the same time it takes to open Wego’s popular travel app"
