(DELHI, INDIA) IndiGo will start a new daily nonstop route from India’s capital to Vietnam’s capital on December 20, 2025, adding steady lift for travelers who need a simple, same-day link between two fast-growing hubs. The airline says the new Delhi to Hanoi service will run every day using an Airbus A320/A320neo, with bookings already open. Schedules show an early morning departure from Delhi and an evening return from Hanoi, designed to suit both business trips and short holidays as peak travel picks up in late December.
Flight pattern and schedule
IndiGo will operate flight 6E 1633, leaving Delhi at 07:25 AM and landing in Hanoi at 1:00 PM (local time). The return, 6E 1634, leaves Hanoi at 6:00 PM and arrives in Delhi at 9:25 PM (local time).
- Aircraft: Airbus A320/A320neo (single-aisle)
- Frequency: Daily
- Start date: December 20, 2025
- Sales status: Reservations are open as of October 12, 2025
The timing aligns with morning connections within India and evening links across Southeast Asia, which may help smooth onward travel according to analysis by VisaVerge.com.
Why this route matters
IndiGo’s Delhi–Hanoi launch expands its India–Vietnam footprint. The airline already flies 14 times per week between Kolkata and both Hanoi and Ho Chi Minh City. Adding daily service from Delhi—the country’s largest metro area—brings:
- More nonstop options for travelers who prefer to avoid connections via Kolkata, Bangkok, or Singapore
- Improved seat availability across the week, which can help stabilize fares
- A schedule suited to business travelers (wrap a business day and return the same night) and short-break tourists or students
The midday arrival in Hanoi is useful for same-day hotel check-ins, afternoon meetings, or catching domestic connections. The evening return allows passengers to finish a business day and get back to Delhi before midnight.
Fleet and operational fit
IndiGo’s use of the Airbus A320 family on this route reflects its broader fleet strategy:
- Familiar aircraft for Indian travelers
- Strong parts support and crew commonality, aiding reliability
- Single-aisle configuration appropriate for a roughly four-hour regional flight
- Cabin setup focused on quick boarding and on-time performance—key selling points for time-sensitive travelers
Broader network context
This launch is part of a wider international push by IndiGo. The carrier has also announced a new daily Delhi–Guangzhou service starting November 10, 2025. Both routes emphasize point-to-point flying from Delhi to major Asian cities using the reliable A320 family, simplifying training, maintenance, and crew planning while adding strategic linkages.
Travel and policy considerations
A nonstop link can reduce overall journey time and the chance of missed connections—important for travelers on firm dates for work, family events, or academic enrollments.
Important travel reminders:
– Verify entry rules well before travel; requirements may include a valid passport, visa or e-visa, proof of funds, and onward travel documents.
– Airlines will check documents at boarding; a nonstop flight does not alter entry requirements.
– For official entry information and e-visa applications, consult the Vietnam government portal: https://evisa.xuatnhapcanh.gov.vn
Travelers should rely on official government sources for policy updates rather than social media. Carry print or digital copies of visas, return tickets, and hotel reservations.
Who benefits
- Indian businesses and exporters: daily nonstops enable quick trips without losing a full day in transit.
- Students and families: morning departures simplify travel days, especially for those preferring daylight travel.
- Frequent flyers and time-sensitive travelers: a nonstop is often the simplest, fastest option.
Airport operations and passenger impact
A daily narrow-body flight brings steady, manageable traffic to both Delhi and Hanoi rather than sudden surges. Benefits include:
- Reduced pressure on connecting hubs and fewer seats tied up on indirect itineraries
- Lower probability of cascading disruptions that lead to visa date issues, hotel rebookings, or rebooking fees
- Improved choices on busy India–Vietnam city pairs and potential relief for connecting routes through other Asian hubs
