Virgin America may tout its flashy interiors, in-flight Wi-Fi and live TV and movies, but the airline took steps to ensure that an improved passenger experience begins with its website  and its mobile capabilities.

If travelers booking a flight on VirginAmerica.com or on mobile noticed that they could complete the transaction quicker than before, the airline says it knows why.

Virgin America earlier this year began off-loading up to 89% of its Web traffic to Akamai Technologies and its cloud-based Akamai Aqua Web Experience Solutions, leading to a 40% improvement in transaction times, the companies say. Virgin America also redirects mobile traffic to Akamai.

Dean Cookson, Virgin America’s CIO, says the move, which went live nine months ago, improved site performance in the airline’s East Coast markets, and provides for a more consistent Web experience overall.

With Winter on the way, and the travel disruptions it usually brings, that’s good news for Virgin America customers.
