Which is the cheapest route from Malaysia to Varanasi?

The cheapest combination is typically AirAsia from KUL to Kolkata (CCU), followed by IndiGo from Kolkata to Varanasi (VNS). AirAsia frequently runs seat sales on the KUL–Kolkata route, and IndiGo’s Kolkata–Varanasi fares are among the lowest domestic segments. Book both legs separately on the respective airline websites rather than through a third-party aggregator to get the best prices.
