In 2017, the country recorded an impressive 1.6 billion domestic travelers. That same year, the number of international arrivals shot up to 10.04 million, representing a 14% uptick compared with 2016, according to the government's latest tourism report, which does not yet offer data on 2018.
And with India being the world's third-largest aviation market, nearly every major airport across the country plans to expand capacity.
So which airports are the busiest?
Here, we look at the country's most popular facilities and what they have to offer travelers. All data has been sourced from the latest annual Airports Authority of India traffic report (April 2018-March 2019).
Indira Gandhi International Airport, Delhi
Passengers: 69.2 million
Efficient and modern, Indira Gandhi International Airport (commonly known as Delhi airport) is the busiest airport in India and the 12th busiest in the world, according to the Airports Council International's preliminary world traffic report released in March.
Foreign travelers will spend most of their time at T3 -- the 2.7 million square foot international terminal -- which is the first LEED-NC Gold certified terminal in India. The building has lots of natural light, as well as electric vehicles and a rainwater harvesting program.
There are all kinds of modern amenities, from a dedicated spa (O2 Spa) to free WiFi, luggage storage, a children's play area, device charging stations and also sleeping pods (such as Sams Snooze at My Space) for some shuteye in between connections.
There's even a flight simulator experience dubbed "The Cockpit" in the international terminal, where you can try your hand at flying a Boeing 737.
Chhatrapati Shivaji Maharaj International Airport Mumbai
Passengers: 48.8 million
Serving India's commercial capital, Chhatrapati Shivaji Maharaj International Airport Mumbai is one of the most beautiful airports in the country.
Opened in 2014, the ultramodern Terminal 2 -- designed by renowned American architecture firm Skidmore, Owings & Merrill -- is particularly pleasant.
The first thing you notice inside the dramatic check-in reception hall? Soaring ceilings and bright white columns that mushroom upwards, bringing to mind a larger-than-life forest.
There are local accents everywhere, from jali-inspired window screens to airy pavilions, mirrored mosaics and lotus-shaped chandeliers.
Then there's Jaya He -- an enormous art museum that plays host to more than 5,000 art pieces, artifacts and installations from around the country.
Better yet, the airport offers free 15-minute guided "Jaya He Safaris" -- you just have to book online ahead of time.
Throughout the terminal, services cover all the bases, including duty-free shopping, rest areas, meditation rooms, free WiFi, several spas and childcare rooms and play areas.
Kempegowda International Airport, Bangalore
Passengers: 33.3 million
Another beautiful architectural project, Kempegowda International Airport in Bangalore debuted in 2008.
Designed by global architecture firm HOK, the elegant structure has stood the test of time with its nature-oriented design.
Steel branches hold up an undulating roof, while sky-high glass walls and lots of greenery nod to Bangalore's reputation as India's "Garden City."
It might look serene from the outside, but this is actually the busiest airport in southern India -- and growing rapidly. By 2030, the airport expects to serve an additional 45 million passengers per year.
The airport also plans introduce a second runway in 2019, with more development projects underway.
The experience is relatively efficient, with self-baggage checks, free WiFi, a boutique day hotel, several lounges, restaurants and duty-free shopping.
Chennai International Airport
Passengers: 22.5 million
Opened in 2013, Chennai International Airport features a column-free terminal with a graceful curved roof.
Constructed with a mix of steel and recycled local materials, the airport's H-shaped structure is designed to minimize the distance traveled by passengers.
Meanwhile, vertical gardens and natural light aim to make the space feel more open and relaxing.
Chennai International isn't yet as streamlined as the top three airports in India, but that's quickly changing.
The government, which runs the airport, has plans to expand capacity to 30 million passengers by 2021.
Currently, facilities are more limited than other major airports -- slow immigration channels, unreliable WiFi, and construction noise are just a few of the headaches.
Netaji Subhas Chandra Bose International Airport, Kolkata
Passengers: 21.8 million
Located in Kolkata, formerly known as Calcutta, Netaji Subhas Chandra Bose International Airport is among India's most modern aviation gateways.
Opened in 2013, the airport's L-shaped international terminal (Terminal 2) sports a pared-back design and uses solar power to offset energy needs.
There are also lots of shopping and dining options, plus services like luggage storage and day beds.
As one of the fastest-growing airports in India, a third terminal is already in the works to keep up with passenger capacity.
With the new terminal, the airport should be able to accommodate up to 40 million travelers annually by 2021.
