"When should I buy plane tickets from Tokyo to Hanoi?"

Flights between Tokyo and Hanoi can be longer and more expensive, so consider using a secondary airport or connecting through another Asian city like Bangkok or Shanghai to reduce your overall travel time.

Look into budget airlines that operate between Tokyo and Hanoi, such as Vietnam Airlines or Jetstar. These airlines often offer lower fares, especially if you book early and travel light.

The most advisable practice is to buy plane tickets from Tokyo to Hanoi several months in advance, roughly 2 to 3 months prior, to secure the best price that is available that early. However, do keep in mind the sales and promotions by airlines, since, under certain rare instances, you might also find deals for relatively cheaper last-minute tickets. Your travel dates will influence pricing significantly, and prices will vary seasonally, on weekends, and on holidays. Relaxing your travel dates could also yield significantly cheaper tickets. Monitor the price and set fare alerts to discover when the costs fall drastically.
