Delhi to Chicago Flights

What's new in Delhi

• October 2025: The rebuilt Terminal 2 at Indira Gandhi International Airport reopened on 26 October 2025 after a closure that began in April 2025, and a share of IndiGo and Air India domestic flights moved into it. Check the terminal printed on the boarding pass before leaving for the airport.
• February 2026: The full 82 km Namo Bharat regional rail corridor from Sarai Kale Khan to Modipuram in Meerut was inaugurated on 22 February 2026, giving south-east Delhi a fast rail link to Ghaziabad and Meerut.
• June 2026: Noida International Airport at Jewar (DXN) began scheduled flights on 15 June 2026, with IndiGo operating the first service. For some domestic routes it is a practical alternative for travellers based in Noida and Greater Noida.

Tips for travellers

For a two or three day stay, Connaught Place, Paharganj and Karol Bagh sit on the Blue and Yellow metro lines, while Aerocity suits early departures because it is next to the airport. The Delhi Metro is the quickest way across the city, and a smart card or a QR ticket bought on a phone saves time at the counters. October to March is the main sightseeing season, though smog can be heavy in November, and Diwali week fills hotels and trains. May and June are extremely hot.

The Red Fort is closed on Mondays. At Jama Masjid and Gurudwara Bangla Sahib, remove your shoes and cover your shoulders and legs; the gurudwara also asks everyone to cover their head and lends scarves at the entrance. Swaminarayan Akshardham does not allow phones or cameras inside, so leave them in the cloakroom or at the hotel.

Tips for travellers from India

The Loop is useful for the Art Institute, Millennium Park and central rail links, while a hotel near O’Hare serves an early flight or suburban appointment. These bases are a substantial distance apart. The CTA Blue Line reaches the airport from downtown, but passengers arriving at Terminal 5 first need the airport connection to the main rail-access area. The airport train and an intercity rail departure from Union Station are separate arrangements.

Air India uses Terminal 5. United domestic flights and international departures use Terminal 1, while many international arrivals are processed through Terminal 5, so an onward connection can involve a building change. In the city, pair the Art Institute with Millennium Park rather than crossing to a distant neighbourhood between them. The Riverwalk offers another central route, while the lakefront extends far beyond the downtown section. The Obama Presidential Center opened to the public in June 2026 in Jackson Park, creating a museum outing on the South Side rather than another stop beside the Loop. Plan that visit as its own district trip. A river architecture cruise also has a specific departure dock, which should be matched to the walking route. Choose between a museum-heavy day and a longer lakefront walk before booking several timed attractions.
