Miles you could earn on this route
Programmes that reward distance credit a percentage of the miles flown, set by the fare you book. Here's what that means on DEL–CCU:
| Earning rate | Typical fares | One way | Return |
|---|---|---|---|
| 25% | Cheapest economy on some airlines | 204 | 408 |
| 50% | Discounted economy | 408 | 816 |
| 75% | Standard economy | 612 | 1,224 |
| 100% | Flexible economy, many premium economy fares | 816 | 1,632 |
| 125% | Premium economy, discounted business | 1,020 | 2,040 |
| 150% | Business | 1,224 | 2,448 |
| 200% | First | 1,632 | 3,264 |
Which rate applies depends on the airline and programme; see how to find your fare class. Programmes that reward spending instead, such as United, Delta, American Airlines and British Airways, give the same miles whatever the distance, based on the fare you pay.

Why an airline may show a different distance
This figure is the shortest path between the two airports on the WGS-84 model of the Earth. Some programmes use industry distance tables between cities or round their figures, so the distance they credit can differ by a few miles.
