Airport and Flight Information

The closest major international airport to the IOAA venue is Noi Bai International Airport (HAN), located approximately 25–30 km from central Hanoi and around 35–40 minutes from Phenikaa University by car, depending on traffic. Noi Bai is Vietnam’s second-largest aviation hub and serves direct flights from many major cities in Asia, Europe, Australia, and the Middle East. Participants arriving from regions without direct connections can typically transit through major hubs such as Bangkok (BKK), Singapore (SIN), Seoul (ICN), Tokyo (NRT; HND), Doha (DOH), Dubai (DXB), or Kuala Lumpur (KUL). Transportation options from the airport include official airport taxis, ride-hailing services (Grab, Xanh SM) , airport buses, and private transfers arranged by the host organizers.

Participants should verify their visa requirements before traveling to Vietnam, as regulations vary by nationality. Most delegations will require either:

A tourist visa (e-visa, valid for short-term visits, approximately 15 - 45 days)

An official visa arranged through the IOAA organizers (if applicable)

Please contact the nearest Embassy or Consulate of Vietnam in your country for the most accurate, up-to-date information.
