Chicago to Copenhagen: Business Class Compared

Choosing between SAS and United for business class from Chicago to Copenhagen is a genuinely interesting decision, and one where the right answer depends almost entirely on what you prioritize in the air. Both carriers operate direct service from O'Hare with fully lie-flat, 1-2-1 configurations offering every seat direct aisle access — a meaningful baseline parity — but the similarities largely end there. SAS Business and United Polaris diverge sharply on atmosphere, dining philosophy, and the ground experience that bookends your nine hours aloft.

United Polaris is the stronger product for travelers who want a consistently polished, hotel-like hard product. The Polaris seat itself is well-engineered with a proper door on select widebody aircraft, generous bedding from Saks Fifth Avenue, and a pre-departure experience anchored by the Polaris Lounge at O'Hare — one of the genuinely excellent domestic airline lounges, with a full à la carte dining room worth arriving early for. United also tends to price this route competitively, particularly on shoulder-season departures, and its connections from across North America into O'Hare make it the more practical choice for travelers originating outside the Midwest.

SAS Business, by contrast, delivers something more distinctly Scandinavian — and that's not a small thing on a flight to Copenhagen. The cabin feels quieter, the service more understated and genuinely warm rather than procedurally attentive, and the food leans into Nordic ingredients in a way that feels authentic rather than performative. The SAS lounge at O'Hare is more modest than the Polaris Lounge, so if your pre-flight ritual matters, adjust expectations accordingly. That said, SAS occasionally releases attractive fares in the summer travel window — May through September — and their positioning as a premium regional carrier means the onboard experience often punches above what the ticket price implies.

For suite seekers and those who rate the ground experience as part of the journey, United Polaris edges ahead. For foodies and travelers who value cabin atmosphere over amenity uniformity, SAS rewards the choice. The insider tip worth knowing: SAS tends to release fare sales mid-week for summer departures, often with shorter booking windows than United's promotional cycles — so setting automated alerts on both carriers simultaneously is the most reliable way to catch the spread when it narrows.
