December is a high-demand month for the Indira Gandhi International Airport (DEL) to Chhatrapati Shivaji Maharaj International Airport (BOM) route due to holiday travel and business trips. Expect 20–40 daily frequencies across nonstop carriers; morning flights can face fog-related delays, so mid-day departures (10:00–16:00) are recommended for reliability.
