RAS question
India's busiest airport (by passenger traffic) is:
Correct answer: (B) Indira Gandhi International Airport, Delhi.
Indira Gandhi International Airport, Delhi is India's busiest airport by passenger traffic.
Explanation
Indira Gandhi International Airport, Delhi ranks first because the ranking is based on passenger traffic, not on the size or prominence of the city. IGI Delhi is India's busiest airport, with Mumbai's CSIA second and Bengaluru's Kempegowda International third. The Airports Authority of India's August 2025 passenger-traffic annexure gives the total passengers in April-August 2025-26 as 30,824,482 for Delhi, 22,545,451 for Mumbai, 18,218,188 for Bengaluru and 9,683,202 for Chennai. Delhi's three-terminal airport system therefore handles the largest passenger flow.
Why the other options are wrong
- (A) Mumbai Airport ranks second because Mumbai's CSIA handled 22,545,451 passengers in April-August 2025-26, below Delhi's 30,824,482.
- (C) Chennai Airport ranks below Delhi because Chennai handled 9,683,202 passengers in April-August 2025-26, far below Delhi's 30,824,482.
- (D) Bangalore Airport ranks third because Bengaluru's Kempegowda International handled 18,218,188 passengers in April-August 2025-26, below both Delhi and Mumbai.
Concept
Transport geography covers the hierarchy of India's aviation hubs by passenger movement. RAS transport-geography coverage often connects airports with urban geography, infrastructure and current economic activity.
