Incredible India is on sale from American Airlines alongside partners Etihad and Jet Airways. The lowest one connection fare I was able to find on this unadvertised sale is from Philadelphia to Mumbai for $512 roundtrip, while many other routes to major Indian cities like New Delhi, Chennai, Kolkata, and Bengaluru are on sale in the low-to-mid 500 dollar range but may require two stops.
Dates range by destination, with most availability on 2019 dates and for the most part, flights are available for departures any day of the week. Many of these routes are bookable through June 2019, but there are some that have earlier last travel dates. You’ll have to play around to see if a particular route will fit into your travel window.
