Are Delhi to Vietnam Flights Cheaper on Weekdays? — A Price Study

Short answer: often yes — but not always. Data from multiple airfare trackers and industry reports show a reliable pattern: midweek departures (Tuesday–Thursday) and some Saturdays tend to be cheaper for international travel, but route-specific factors, airline capacity, seasonality, and recent market disruptions can flip that pattern for Delhi to Vietnam flights.

What the numbers and studies say

Large aggregator analyses and airline-data reports from 2024–2025 generally find that international fares are lower midweek — Expedia’s 2025 data, for example, highlights Thursday as a consistently cheaper day to fly internationally and shows measurable percentage savings versus weekends. That broad-market signal applies to many long- and short-haul routes. Flight Risen Travels

At the route level, live-search snapshots from platforms such as Skyscanner and KAYAK show price spreads on the Delhi ↔ Hanoi / Ho Chi Minh corridors where one-way and round-trip fares can vary by several thousand rupees depending on travel day, how far in advance you book, and whether the itinerary is non-stop or has connections. For certain dates, non-stop routings offered by carriers can be notably pricier than one-stop options — but when low-demand midweek seats exist on non-stop flights, savings are possible.

Why are weekdays cheaper for Delhi to Vietnam flights

1. Lower leisure demand midweek. Weekends and long holiday windows attract leisure travelers; midweek travel is mainly business or highly flexible leisure, so airlines often price those seats lower. PR Newswire
2. Seat inventory & revenue management. Airlines use dynamic pricing systems that factor in booking curves — if a midweek flight has unsold inventory, the algorithm may reduce fares to stimulate demand. PR Newswire
3. Connecting vs non-stop dynamics. Non-stop International flights in Delhi (when operated on DEL→HAN/SGN routes) are more convenient but sometimes carry a premium; cheaper fares can appear on midweek dates when airlines aim to fill those premium seats. Vietnam Airlines+1

When weekdays won’t help

• Peak festivals or school holidays: Demand spikes around Diwali, Christmas/New Year, and Indian school breaks can push weekday fares up — sometimes weekdays are as expensive as weekends. PR Newswire
• Operational changes/capacity cuts: Recent airline schedule adjustments or regulatory actions that reduce seats (e.g., temporary cuts by a major carrier) can remove the usual midweek discounts. Always check for market news before assuming weekdays = cheap. The Times of India

Practical price-checking method (quick study you can run in 10–15 minutes)

1. Search a fare calendar on two aggregators (Skyscanner, KAYAK, or Google Flights) for the same one-month window. Compare fares for Tuesdays–Thursdays vs. Fridays–Sundays. Skyscanner+1
2. Compare non-stop options (if available) separately from one-stop itineraries — label them and note the average difference. Vietnam Airlines
3. Run the checks at different lead times: 1 month, 2–3 months, and 6+ months out to see booking-window effects. Industry reports suggest the “sweet spot” varies, but international fares often show best value in specific booking windows closer to departure than people expect. Investopedia+1
4. Set price alerts for the exact route and dates; alerts will catch short-lived midweek dips that one-off searches miss. Skyscanner

Tips to take advantage of weekday savings

• Be flexible by ±2 days. If the cheapest fare is on a Wednesday, shifting your trip by a day can cut the ticket price. (Repeat searches quickly to confirm.) PR Newswire
• Check non-stop vs connecting separately. If you prefer comfort, compare the premium for non-stop International flights in Delhi against cheaper connecting itineraries — sometimes a price difference is worth the time saved. Vietnam Airlines
• Book at recommended lead times for international travel (monitor reports and aggregator guidance) rather than booking months in advance or waiting until the last minute.
• Use price alerts and refresh calendars midweek — you’re more likely to catch a dip on a Thursday or Tuesday. Skyscanner

Example (real-world snapshot)

Aggregators sometimes show round-trip Delhi to Hanoi options with significant day-to-day variation — one recent crawl found one-way fares as low as ~₹7,000 on carriers and dates, while other dates were 2–3× higher depending on timing and stops. This demonstrates why checking weekdays specifically can pay off.

Bottom line

For Delhi to Vietnam flights, weekdays (especially Tuesday–Thursday and occasionally Saturday) tend to offer lower fares, but the effect isn’t guaranteed. The answer for your trip depends on: exact travel dates, whether you need non-stop travel, current airline capacity, and broader market events. If you want the cheapest possible fare for a specific month, do a small weekday vs weekend comparison across 2–3 aggregators and set price alerts that an empirical check will give you the fastest, route-specific answer.
