What Else Did IndiGo Announce?

IndiGo will offer its IndiGoStretch business product on the route. It includes complimentary hot meals, wider seats with extra legroom, deep recline, adjustable headrests, in-seat charging and priority services (IndiGo, 2026). Customers can book through the IndiGo website, mobile app, 6Eskai AI chat assistant and authorised travel partners.

IndiGo already flies daily from Delhi and Kolkata to Hanoi, so Mumbai becomes its third Indian gateway to the Vietnamese capital. AeroRoutes reports that an Airbus A321neo will operate the Mumbai route (AeroRoutes, 2026). The press release does not name the aircraft, the Mumbai airport or the fares.

Is IndiGo the First Airline to Fly Mumbai to Hanoi Nonstop?

No. Akasa Air began Mumbai-Hanoi service on 4 September 2026 with four weekly flights (TravTalk India, 2026). Booking platforms also list Vietnam Airlines and VietJet Air as nonstop operators, with frequencies that differ by source. IndiGo’s advantage is its daily frequency.

What Does the New Route Mean for Travel Agents?

The 10:00 arrival lets groups reach a central Hanoi hotel around midday, so agents should request early check-in. The 19:05 departure leaves most of the last day free for sightseeing. The 04:15 departure from Mumbai means an overnight airport transfer, so agents should keep the first afternoon light. Daily flights also let agents match arrival dates to tour start dates for northern Vietnam circuits such as Ha Long Bay and Ninh Binh.
