Flights from Chicago O’Hare International Airport (ORD) to Singapore Changi Airport (SIN) currently require at least one stop.
As of September 2026, there are no scheduled nonstop passenger flights between Chicago and Singapore. Current one-stop options involve approximately 19 hours 40 minutes to 21 hours 25 minutes of combined flying time, before the layover is added.
The complete journey will therefore be longer than the time spent in the air. How much longer depends mainly on the airport used for the connection and the length of the wait between flights.
Chicago and Singapore are approximately 9,357 miles (15,059 km) apart in a straight line.
Chicago-to-Singapore itineraries can take travelers in very different directions.

The direction of travel alone does not tell you which option will be quickest. A well-timed connection can sometimes make a geographically longer route competitive with another itinerary.Across the Pacific
Through Europe or the Middle East
Current schedule combinations show noticeable differences depending on where the aircraft stops.
Among the currently listed options, Taipei has one of the shortest combined flying times at approximately 19 hours 40 minutes. These figures exclude the airport layover.
This distinction is important because the route with the least time in the air is not necessarily the itinerary with the shortest overall duration.
One of the shorter current routing combinations travels through Taipei Taoyuan International Airport (TPE).
The journey is divided into two sectors:
Chicago → Taipei: approximately 15 hours
Taipei → Singapore: approximately 4 hours 40 minutes
Together, that produces approximately 19 hours 40 minutes of combined flying time.
The connection at Taipei still needs to be added before calculating the complete Chicago-to-Singapore journey.
For example, a relatively short transfer could keep the itinerary close to the combined flight duration, while a lengthy wait could increase the trip by several hours.
Singapore stays on Singapore Standard Time (SGT), UTC+8, throughout the year.Chicago changes between daylight and standard time.
That means Singapore is:13 hours ahead when Chicago is on Central Daylight Timeand14 hours ahead when Chicago is on Central Standard Time
In September 2026, Singapore is currently 13 hours ahead of Chicago.
This large time difference, combined with a journey involving roughly 20 hours or more of flying plus a connection, means the arrival date moves well ahead of the departure date shown in Chicago.
A Monday departure from Chicago, for example, can result in arrival in Singapore on a later local calendar date depending on the flight schedule and layover.
When arranging accommodation, transport or another flight, use the local Singapore arrival date printed on your itinerary.
