Only the Dallas→Cancun route is practical by car (2,110 km by road). The other route requires flying.
London (United Kingdom) has a population of 8,982,000 and is located in the England region of Europe. As a major metropolis, it offers extensive international connections and diverse attractions.
Cancun (Mexico) has a population of 888,797 and is situated in Yucatan, North America. This destination offers a more intimate travel experience with unique local culture.
Choose this route if your priority is reaching London (United Kingdom) — a city of 8,982,000 in the England region of Europe. Despite being the longer of the two at 7,641 km, it makes sense when London itself is the destination, the schedule fits better, or ticket prices are noticeably lower. This is a fly-only route in practice — overland travel is not realistic at 7,641 km. The initial bearing is 42° (NE), so a great-circle flight leaves Dallas heading roughly NE.
This route is the right call if you are heading to Cancun (Mexico) — a city of 888,797 in the Yucatan region of North America.

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
