How UDAN Makes a Flight Affordable
1.1 What does UDAN actually promise a passenger?
UDAN stands for “Ude Desh ka Aam Nagrik,” meaning let the common citizen fly. It is India’s regional air-connectivity scheme. On a covered route, airlines must sell at least half their seats at a capped fare, around ₹2,500 for an hour of flying, roughly a 500 km trip. The rest of the seats can be sold at the normal market price.
1.2 Which aircraft actually fly these routes?
UDAN routes typically use small regional aircraft, like the ATR 72, rather than large jets. These planes work well on short hops between smaller cities, where passenger numbers don’t justify a bigger aircraft. That’s part of why UDAN focuses on Tier-2 and Tier-3 cities, not major metro-to-metro routes.
Q1. True or False: On a covered UDAN route, airlines must sell at least half their seats at a government-capped fare.
Who Pays, and Who Runs It
2.1 How does UDAN cover the cost of a cheap ticket?
UDAN uses Viability Gap Funding (VGF), government support that covers the difference when a route isn’t commercially viable on its own. Think of it like a bridge loan for an airline’s revenue. If the low, capped fares don’t cover an airline’s real cost of flying the route, VGF pays the gap.
2.2 Where does that VGF money actually come from?
State governments cover 20% of VGF cost for routes touching their own state. A small levy on tickets for busy, profitable domestic routes funds the rest. So popular routes effectively subsidise small ones, a first-of-its-kind funding model compared to countries like the US and Australia. On the ground, the Airports Authority of India (AAI) implements the scheme.
Q2. True or False: The central government alone funds UDAN’s Viability Gap Funding, with no state contribution.
From a Fast Start to a Slow Middle
3.1 How quickly did UDAN go from policy to an actual flight?
UDAN launched on 21 October 2016, conceptualised under NCAP 2016, with a 10-year vision to connect Tier-2 and Tier-3 cities. The first UDAN flight took off just six months later, on 27 April 2017, when PM Modi inaugurated the Shimla-Delhi route. That pace was unusually fast for a subsidy scheme. Most infrastructure programmes take years longer to reach an operating route.
3.2 Did that fast start actually hold up?
Not smoothly. By 31 May 2021, five years in, UDAN had operationalised only 47% of total planned routes and 39% of unserved or underserved airports, per ICRA data. Real progress has picked up since then. By July 2026, UDAN reached 679 routes across 95 airports, heliports, and water aerodromes, carrying over 1.68 crore passengers on more than 3.58 lakh flights.
Q3. True or False: By mid-2021, UDAN had operationalised more than 90% of its planned routes.
Turning Old Airstrips into Airports
4.1 Does UDAN only build brand-new airports?
No. UDAN also revives old, unused airstrips, bringing previously served but abandoned airports back into service. That’s often cheaper and faster than building a new airport from scratch, since the runway and basic infrastructure already exist.
4.2 How much has India’s airport count actually grown?
India’s airport count grew from 65 in 2001, to 74 in 2014, to 164 today. That’s 90 new airports in the last dozen years, including 55 revived unused airstrips. Roughly six out of every ten new airports came from reviving something old, not building something new.
Worth remembering: UDAN isn’t purely a construction scheme. Reviving old airstrips is a bigger part of its growth story than building new ones from scratch.
Q4. True or False: Most of UDAN’s new airports came from reviving old, previously unused airstrips, not from building entirely new ones.
Modified UDAN and Viksit UDAN
5.1 What did the Cabinet approve in March 2026?
In March 2026, the Cabinet approved Modified UDAN, committing ₹28,840 crore over ten years, from FY 2026-27 to FY 2035-36. The plan adds 100 more aerodromes and 200 helipads. VGF support for airline operators now runs 5 years instead of 3, tapering from 75% of the awarded VGF in Year 3 down to 25% in Year 5.
5.2 What is Viksit UDAN, and what came with it?
On 4 July 2026, PM Modi launched “Viksit UDAN,” the scheme’s next phase, and inaugurated a new terminal at Jodhpur Airport at the same event. The terminal handles 1,500 passengers an hour. On 16 July 2026, Minister Ram Mohan Naidu flagged off Daman’s first-ever direct flight, from the new NAMO Airport, cutting Daman-Delhi travel time from 8-10 hours to just 2.5 hours.
Q5. True or False: Viksit UDAN and Modified UDAN are two entirely separate, unrelated schemes.
Traps Worth Knowing Before Your Exam
6.1 What trap hides inside a UDAN full-form question?
SSC CGL 2024 cited the exact 2021 ICRA rollout figures, 47% of routes and 39% of airports operationalised, then simply asked for UDAN’s full form: Ude Desh Ka Aam Naagrik. These papers sometimes bury a simple full-form question inside a specific, dated statistic, to test whether you can spot the actual question underneath. Don’t let a dense statistic in the question stem distract from what’s actually being asked.
Quick Q&A
What does UDAN stand for?
Ude Desh ka Aam Nagrik, let the common citizen fly. It’s India’s regional air-connectivity scheme.

Viability Gap Funding (VGF), which covers the gap when capped fares don’t cover an airline’s real cost.
Which agency implements UDAN on the ground?
The Airports Authority of India (AAI).
What was UDAN’s real progress by mid-2021, per ICRA data?
Only 47% of planned routes and 39% of unserved/underserved airports had been operationalised.
What did the Cabinet approve for Modified UDAN in March 2026?
₹28,840 crore over ten years, FY 2026-27 to FY 2035-36, adding 100 aerodromes and 200 helipads.
