How these estimates work
Straight-line distance uses the haversine formula on each city's coordinates. Road distance applies a circuity factor (~1.2–1.4×) and driving time a blended average speed. Flight time uses typical jet cruise speed plus ~30 minutes for taxi, climb and descent. Treat all figures as planning estimates.
