The sheer ambition of this routing is what strikes you first — Chicago to New Delhi is not a journey you stumble into casually, and the airlines that serve it reward those who plan with intention. United operates this corridor through its Polaris business class product, typically connecting via Newark or Washington Dulles, where the carrier's international widebody fleet takes over. Polaris remains one of the more genuinely lie-flat experiences in transatlantic and transpacific premium cabins, with direct-aisle access from every seat a meaningful advantage on a journey pushing fifteen hours. Air India, meanwhile, has been quietly transforming its long-haul offering, and its reborn business class on the Delhi run — particularly on newer configured aircraft — deserves serious reconsideration from travelers who last flew the carrier a decade ago and wrote it off.
Timing this route well is half the art. The sweet spot for both availability and comfort lands firmly in the shoulder months: January through early March sees strong seat availability as leisure traffic thins after the holiday surge, and October through December offers a similar opening before the festive travel wave builds. Delhi's Indira Gandhi International Terminal 3 handles international arrivals with surprising efficiency for a facility of its scale, though immigration queues during peak festival periods can test even the most patient traveler — arriving in the early morning hours tends to ease that particular friction considerably.
From O'Hare, the international terminal experience matters more than most Chicago travelers realize. United's Polaris Lounge access at ORD has improved markedly in recent years, making pre-departure time genuinely restorative rather than merely tolerable — a quiet advantage before you settle in for one of the longest hauls departing the American Midwest.
