What This Distance Means for Your Trip
At 214 miles, this is a driving distance rather than a flying one — and a train or bus is often an option too. A scheduled flight would cover only about 165 miles in the air, and once you factor in getting to the airport, checking in and clearing security, that airport time alone cancels out anything saved aloft. For a trip this length, driving is almost always the practical choice.

How we calculate these figures
Straight-line distance uses the great-circle (haversine) formula between each city's centre coordinates. Road distance applies a circuity factor of roughly 1.2–1.4× to reflect that roads are not straight. Driving time assumes typical blended speeds for a trip of this length, and flight time is the great-circle distance at about 875 km/h cruise plus around 30 minutes for taxi, climb, descent and approach. The door-to-door air estimate adds about three hours for airport access, check-in, security and boarding. Real figures vary with your exact route, traffic, weather, aircraft and connections.
