IndiGo’s net profit in the fourth quarter declined 25% to Rs440 crore despite 59% jump in other income during the quarter. The good thing is the airline’s yields declined 4% year-on-year, comparatively slower than the previous two quarters (see the chart alongside). Yield refers to pricing and is calculated as passenger ticket revenue divided by revenue passenger kilometre. Further, the airline has decided to buy turboprop planes to enter into regional aviation operations. Typically, regional aviation operations enjoy lower margins.
