Singapore to Kolkata (SIN-CCU): nonstop upgrade & award space

Singapore Airlines and IndiGo fly the SIN to CCU nonstop about 10 times a week.

Departure and arrival times are local at their own airport, so an arrival can fall on a different local date than the departure; the duration column is the true elapsed flying time.
