Fly Direct with Budget Carriers
The single best way to save time and often money is by choosing a direct flight on a low-cost carrier. Airlines like VietJet Air and IndiGo have significantly expanded their direct routes from major Indian hubs to Vietnam. As of 2026, you can find non-stop
flights from cities including Delhi, Mumbai, Kolkata, Ahmedabad, and Bengaluru to Hanoi (HAN) and Ho Chi Minh City (SGN). While full-service carriers like Air India and Vietnam Airlines also operate these routes, the base fares on budget airlines are typically much lower. A direct flight from Kolkata to Hanoi can be as short as three hours, making it an incredibly efficient option. Just remember the trade-off: these fares usually don't include checked baggage or meals, so pack light to avoid extra fees.
Master Your Travel Timing
Your travel dates are one of the biggest factors influencing price. To get the best deals, plan to fly during Vietnam's 'shoulder seasons'—typically April to June and September to November. During these months, fares can be significantly lower than during the peak tourist rush. Conversely, avoid major holiday periods in both India and Vietnam. Another key strategy is booking well in advance. Most experts recommend securing your tickets at least two to three months before your departure date, with some suggesting a window of up to six months for the absolute best prices. Flying mid-week, particularly on a Tuesday or Wednesday, also tends to be cheaper than travelling on weekends when demand is higher.
Embrace a Strategic Layover
While direct flights are convenient, don't dismiss one-stop options. Flights with a layover in other Southeast Asian hubs like Bangkok (BKK), Kuala Lumpur (KUL), or Singapore (SIN) can sometimes be dramatically cheaper. Airlines such as AirAsia, Scoot, and Batik Air (formerly Malindo Air) often offer competitive fares on these routes. For a seven-day trip, the key is to find a layover that is long enough to provide savings but short enough that it doesn't consume a whole day of your vacation. A layover of two to four hours is often the sweet spot. According to some analyses, a connecting flight is worth considering if the savings are 30% or more compared to a direct flight. This option is especially useful for travellers flying from Indian cities without direct Vietnam connections, like Chennai.
Be Flexible with Your Airports
For a week-long trip, you have a choice between exploring the north or the south of Vietnam. Don't just default to one arrival city. Compare the flight prices for flying into Hanoi's Noi Bai International Airport (HAN) versus Ho Chi Minh City's Tan Son Nhat International Airport (SGN). Sometimes, the price difference can be substantial. For a 7-day itinerary focused on one region, this flexibility can unlock significant savings. For instance, if your goal is to see Ha Long Bay, flying into Hanoi is your best bet. If the Mekong Delta is on your list, aim for Ho Chi Minh City. Use flight comparison websites to check fares to both cities simultaneously before you lock in your plans.
Use Price Comparison Tools Wisely
Instead of checking airline websites one by one, start your search with flight aggregator sites like Skyscanner, KAYAK, or Google Flights. These tools allow you to compare dozens of airlines and routes in a single search, giving you a quick overview of your options. One of the most powerful features they offer is the price alert. You can set an alert for your desired route and receive notifications when the fare drops, allowing you to book at the optimal moment. However, once you find a flight you like, it’s always a good idea to check the airline's own website. Occasionally, airlines run exclusive promotions that aren't available through third-party sites.
Travel Light to Avoid Baggage Fees
This tip is especially critical when flying with budget airlines. The low base fare you see at booking can quickly inflate if you're not careful about baggage. For a 7-day trip, challenge yourself to pack everything into a single carry-on bag that meets your airline's size and weight restrictions. This allows you to bypass checked baggage fees, which can be surprisingly expensive. If you must check a bag, always pay for it online in advance. Purchasing baggage allowance at the airport check-in counter is almost always the most expensive option. Reducing your load is a simple but highly effective way to keep your overall flight cost down.
