On Vietnam Airlines, the cost to check an extra bag depends on your route and when you pay it: a standard extra 23 kg checked bag at the airport is typically around VND 600,000 on domestic flights and about USD 110–260 on international routes (India usually falls in the Asia zone, often around USD 150–200 per extra bag), and it can be cheaper (up to ~50% less) if you pre-book it online before departure through the airline’s website or Manage Booking section.

On Vietnam Airlines, upgrading to Premium Economy after booking is sometimes cheaper during promotions or online “manage booking” offers, but in many cases it’s more expensive than booking Premium Economy from the start, since upgrade prices depend on seat availability, route demand, and timing; the best chance for a cheaper upgrade is checking early in “Manage Booking” or at check-in when the airline offers discounted upgrade deals.

Yes, Vietnam Airlines is generally a good option for international flights, offering reliable long-haul service, decent comfort, included meals, and reasonable baggage allowances, with a solid safety record and membership in SkyTeam, though it’s not as premium or consistently polished as top-tier global airlines, so it’s best viewed as a dependable mid-to-upper range carrier rather than a luxury one.

Vietnam Airlines Flight 474 crash happened on 14 November 1992 and is officially classified as a controlled flight into terrain (CFIT) accident. During the approach to Nha Trang Airport in bad weather linked to a tropical storm, the aircraft descended below the safe minimum altitude while still in clouds and poor visibility, lost situational awareness, and hit mountainous terrain short of the runway—meaning there was no mechanical failure, but the plane was flying too low for the surrounding terrain and crashed into a ridge.
