Frequently asked
Which side of the plane avoids the sun from LHR to ORD?
Across typical daytime departures, the sun predominantly hits the left side of the aircraft, so the right side stays shadier. Seat letters start at the left window, so choose the highest window letter (F on narrowbodies, K on many widebodies).
Which side has the sunset views on LHR to ORD flights?
For sunrise or sunset views, sit on the side the table marks as the sun side for your departure time — that is where the light is.
How long is the flight from LHR to ORD?
The great-circle distance is 6,344 km (3,942 mi), which works out to roughly 7h 58m in the air on this westbound routing. Winds and routing move the real block time around that estimate.
Does the date or departure time change the answer?
Yes — that is why the table shows both. The sun's path shifts with the season, and a morning departure can put the glare on the opposite side compared to an evening one. For a specific flight, the calculator samples the sun along the whole route for your exact date and time.
