How cheap have Kolkata to Hanoi flights been in 2026?

Methodology and limitations

Source: Gotixi deals imported into flipt.in. We include retained active and inactive deals, use the source's last verification timestamp as the observation date, and group by origin airport, destination airport, cabin and UTC observation year—not travel year. Prices are listed round-trip fares per adult in INR.

The sample size counts distinct source deal IDs, not searches, seats, bookings or repeated checks. Invalid prices, ambiguous airport pairs, unsupported cabins and invalid or future observation dates are excluded. Pages require at least 3 distinct deals. Routes are ranked by sample size, which reflects our coverage rather than passenger popularity.

We retain only the latest stored price and verification date for each deal. Earlier prices overwritten by refreshes cannot be reconstructed; samples and minima can change as deals are updated. Multiple deals may cover similar itineraries. This is a curated, incomplete sample, not a continuous price archive, an annual all-time low or an average market fare. No missing months are estimated. Baggage, stops and fare rules can differ.
