Flight Time from Chicago (ORD) to Astana (NQZ)

Non-stop, the ORD–NQZ sector prices out at 11.81 hours — 9,473 km at 850 km/h plus 40 minutes of taxi, climb and approach. Each stopover adds ground dwell at the hub, so the totals model out to about 15.3 hours for one stop and 19.3 for two.

Past the 9,000 km mark this is an ultra-long-haul sector: the 11.81 hours in the air plus cabin time makes a one-stop routing with a lounge stop worth pricing against the non-stop. The clock moves 11 h forward (UTC−6 → UTC+5), so a morning departure can land well into the local evening.

If fares into NQZ spike, the airports tabulated below are the first places to check; each row shows the distance back to Astana and the flight time from Chicago. That leaves ORD → NQZ as the only sensible air routing, which concentrates fare power in a single search.

None of these nearby fields has a paired calculator page from ORD yet, so use the distance and time columns to estimate any rerouting yourself. Ground transfer from the alternative airport back into Astana is the catch for arrivals off the ORD service: the 0 km back-offset is time you must win back in fare savings.

Leave Chicago at 10:00 and the local arrival clock in Astana reads about 08:49, which tells you whether day one is recoverable. Hotel, meal and transit averages put a Astana day at $104 against $230 in Chicago — worth weighing against any fare premium for better flight times.

On those numbers Astana is the cheaper place to linger — the gap is $126 per day, which over a week funds a second flight. With 11 hours gained eastbound, the 9,473 km out to Astana ends in a serious jet-lag bill — plan a quiet first day.
