Methodology and limitations

Source: GoTixi drops, including expired and archived ones. We use each drop's last price check (or creation date) as the observation date, and group by origin city, destination city, cabin and UTC observation year, not travel year. Prices are listed fares per adult in INR.

The sample size counts distinct drops, not searches, seats, bookings or repeated checks. Drafts, invalid prices, unsupported cabins and invalid or future dates are excluded. Pages require at least 3 distinct drops. Routes are ranked by sample size, which reflects our coverage, not passenger popularity.

We retain only the latest stored price for each drop, so earlier prices overwritten by refreshes cannot be reconstructed. This is a curated, incomplete sample, not a continuous price archive, an all-time low or an average market fare. Baggage, stops and fare rules can differ.
