San Diego to Chicago
3h 52mgate to gate
The flight from San Diego International Airport (SAN) to Chicago O'Hare International Airport (ORD) covers 2,768 km (1,720 miles) and takes approximately 3h 52m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 60°, passing near 38.3° N, 103.5° W at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 2,768 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 3h 26m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 3h 52m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
2,768 km / 805 km/h = 3h 26m airborne
+ 25 min ground = 3h 52m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 5h 02m | 5h 27m |
| Narrowbody jet (A320, 737) | 780 km/h | 3h 33m | 3h 58m |
| Widebody jet (777, 787, A350) | 900 km/h | 3h 05m | 3h 30m |
| Private jet (Gulfstream) | 850 km/h | 3h 15m | 3h 41m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions this plate answers
How long is the flight from San Diego to Chicago?
A non-stop flight from San Diego (SAN) to Chicago (ORD) takes about 3h 52m. The great-circle distance is 2,768 km (1,720 miles, 1,495 nautical miles), flying north-east on an initial bearing of 60°.
How far is San Diego from Chicago?
2,768 kilometres in a straight line over the earth's surface — 1,720 miles or 1,495 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between SAN and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 2,768 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
