WN1248 route overview: BWI to MDW

WN1248 distance and great-circle path

WN1248 covers 981 km, or 609 miles. That makes it a short-haul flight, a single-aisle hop where turnaround time matters more than range. Of the 439 routes we track, it ranks 386 by distance.

The plane leaves Baltimore heading west. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the BWI-MDW route appears on a tracker map.

Why WN1248 block time differs from cruise time

The schedule allows 2.2 hours from gate to gate. That works out to about 453 km/h. A Boeing 737-700 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See what really moves flight times.

Can the Boeing 737-700 comfortably fly WN1248?

Not at all. At roughly 16% of its range, this is an easy trip for a Boeing 737-700. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 737-700.

How much CO2 does WN1248 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737-700, the aircraft normally flying this route. Carbon dioxide only - see the method below.

CO2 per passenger95 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 95 kg cabin average and a flat bed well above it.

79 kg CO2 per seat
Business15 seats, 12 flown
228 kg CO2 per seat

Taken whole, WN1248 emits what 166 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 558 km, or 2,709 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 926 km sector, the only published sector for this type, applied to this route's 981 km unadjusted. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put WN1248 against another flight.
