Booking Strategy
For Bangkok to Hanoi, book 3-6 weeks ahead for optimal pricing. The sweet spot is typically 4 weeks before departure when airlines release their discounted inventory. Tuesday and Wednesday departures are consistently €15-30 cheaper than weekend flights. Thai Vietjet Air and AirAsia offer the lowest base fares but factor in baggage costs – pre-booking 20kg online adds €20-25 but is still cheaper than at-airport fees. Avoid booking during Vietnamese Tet (January/February) and Christmas period when prices spike €50-80. Use Skyscanner or Google Flights to track price changes, then book directly on airline websites to avoid third-party booking fees and ensure better customer service for changes. Vietnamese airports charge airport tax included in ticket price.
Route Tips
- Book Thai Vietjet Air directly on their app or website – they match prices and often have exclusive promo codes not on aggregators
- Vietnam visa on arrival is available for most nationalities but requires pre-approval letter (€15-25) – apply 5-7 days before arrival
- Arrive at BKK 2 hours before departure – Thai Vietjet closes check-in 45 minutes before flight, earlier than most carriers
- Consider flying into Hanoi and out of Ho Chi Minh (or vice versa) – open-jaw tickets often cost similar and maximize your Vietnam time
- Download Grab app before arrival in Hanoi – it’s the most reliable transport and often 40% cheaper than taxis
- If Vietnamese Tet (Lunar New Year) falls during your travel dates, book 2+ months ahead and expect 50% higher prices
- BKK Terminal 1 has better food options than Terminal 2 – allow time for a proper meal before the 2h flight

What airport do I fly into in Hanoi?

Terminal 1 handles international arrivals including Bangkok flights, while Terminal 2 opened in 2015 for domestic routes. From the airport to central Hanoi (Old Quarter), options include: Airport bus (line 07 or 17) at VND 30,000-50,000 (€1.10-1.80), taking 45-60 minutes; GrabCar/ taxi at VND 250,000-350,000 (€9-13), taking 30-40 minutes; or private transfer at €15-20. Official taxi counters are outside Terminal 1 arrivals.
How far in advance should I book Bangkok to Hanoi flights?
For this route, book 3-6 weeks ahead for the best balance of availability and price. Airlines typically release their cheapest seats 6-8 weeks before departure, then increase prices as inventory sells. Booking 2 weeks ahead risks limited availability and higher prices. However, last-minute deals occasionally appear 3-7 days before departure when airlines try to fill remaining seats – these can drop to €70-90 but require flexibility. Avoid booking more than 8 weeks ahead as prices haven’t adjusted to actual demand yet.
Is it cheaper to fly from Bangkok to Hanoi on weekdays?
Yes, Tuesday and Wednesday departures are typically €15-30 cheaper than Friday-Sunday flights. This pattern holds consistently across all airlines on this route due to lower business and leisure demand midweek. Monday and Thursday prices fall in between weekend and midweek rates. The difference is most pronounced for budget carriers like Thai Vietjet Air – a Sunday departure might cost €120 while the same flight on Tuesday could be €90. If your schedule is flexible, shifting departure by 1-2 days can save significant money.
