Via Airfare Spot, there are fares from New York, Los Angeles, and San Francisco to Delhi starting at $471 roundtrip.
Travel is available from late February through mid-May on Air China and on China Southern. I found these fares using airfare metasearch site Momondo.
Airfare Spot also highlights New York to Bangkok or Phuket from $497 roundtrip, with travel mid-February through mid-April.
You’re flying in coach. If you buy one of these you aren’t going to upgrade. But it’s a super cheap opportunity to fly.
