Case Study: Wizz Air achieves mobile-first, localized digital growth with Welocalize

Wizz Air Soars New Heights with Welocalize Solutions for Digital Content

Wizz Air, one of Europe’s fastest-growing low-cost airlines and the largest in Central and Eastern Europe, faced the challenge of delivering a consistent, locally relevant digital customer experience as it expanded into new markets. To meet language and cultural requirements across web and mobile channels—and support a mobile-first customer journey including three‑click express booking and a loyalty program of more than one million Wizz Discount Club members—Wizz Air partnered with Welocalize for multilingual content and mobile testing services.

Welocalize implemented a centralized localization program and content-lifecycle services (content creation, source review, localization, transcreation) and provided on‑demand global facilities for agile functional and linguistic UI testing of mobile applications. These solutions helped Wizz Air streamline growing digital content volumes, improve mobile user experiences across web (65% of visitors) and app (35%), and support the airline’s rapid expansion to 140+ destinations, reinforcing its position as a top‑visited airline site and enabling faster market rollouts.
