About the Buenos Aires → Belo Horizonte route

The route from Buenos Aires, Argentina to Belo Horizonte, Brazil covers roughly 2,164 kilometres in a northeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 3.5 hours. Both cities sit in the southern hemisphere, so summer and winter align. June is the depth of winter at both ends; December is peak daylight.

Buenos Aires is in the subtropics. Day length varies by roughly two hours between summer and winter; light remains a reliable circadian cue most of the year.
