Flight Time from Chicago (ORD) to Copenhagen (CPH)

Block time for Chicago → Copenhagen is about 8.71 hours non-stop on the site's cruise model. Each stopover adds ground dwell at the hub, so the totals model out to about 12.2 hours for one stop and 16.2 for two.

The clock moves 7 h forward (UTC−6 → UTC+1), so a morning departure can land well into the local evening.

If fares into CPH spike, the airports tabulated below are the first places to check; each row shows the distance back to Copenhagen and the flight time from Chicago. From ORD, reaching BER instead takes about 1.1 h — less airborne time than the 8.71 h non-stop, and the surface leg into Copenhagen still has to be won back.

Where a matching calculator page exists (ORD → BER, ORD → OSL among them) the links are in the Related list below. Remember the destination is the point: any airport below that adds more than a couple of hours of surface time to reach Copenhagen needs a substantial fare gap to justify.

Put a departure hour on the math: wheels-up at 10:00 from ORD puts you on the ground at CPH around 01:43 local time, once the 7-hour gain is applied. Budget the ground side too: a standard day runs $240 in Copenhagen versus $230 in Chicago (hotel, three meals, two transit rides), so the arrival city sets the trip's marginal cost.

On those numbers Chicago is the cheaper place to linger — the gap is $10 per day, which over a week funds a second flight. With 7 hours gained eastbound, the 6,840 km out to Copenhagen ends in a serious jet-lag bill — plan a quiet first day.
