In May, CNN’s special series Road to ASEAN continues its journey to Vietnam to profile two companies that are taking advantage of the country’s growth to expand throughout Asia. Vietnam’s increasing wealth is fuelling rapid expansion in the country’s airline industry. CNN looks at how budget airline VietJet Air is helping millions of people to fly for the first time.

CNN will also take a look at the country’s thriving app scene, where developers are encouraged to look beyond Vietnam and consider all of ASEAN as their potential market. CNN looks at two entrepreneurs who are using that advice to build their app: Hai Ho and Ha Lam, the founders of Triip.me, which is designed to help travelers connect with local tour guides.
