Smartphone usage is growing strongly worldwide, with mobile internet users expected to outnumber desktop users within five years. This is driving increased investment in mobility technologies, especially in the GCC region which saw 60% growth in smartphone demand last year. By 2013, 70% of airlines expect to sell tickets directly via mobile phones, with nearly 15 billion mobile tickets projected to be delivered worldwide by 2014. Mobile services provide benefits to both airlines and passengers, including increased revenue, improved customer satisfaction, and a smoother travel experience. Leading airlines offer comprehensive mobile apps that allow booking, ticketing, flight status checking, lounge access, and other services.
