A 43% increase in app downloads and a 40% increase in user visits in the year to September is being claimed by European OTA owner eDreams ODIGEO.
The growth follows the introduction of new functionalities designed to simplify and improve the travel experience.
More than 40% of bookings are now made on mobile devices.
The company has implemented new free services, including a flight status tracker, which have led to a threefold increase in users’ session length.

“Our industry-leading apps are proving to be the best travel companion for our customers, who seek to simplify their experience with tools that make travel easier at no cost.
