At least eight flights made by the aircraft Lamia Airline prior to the incident in which players Chapecoense crew died, violated aviation regulations relating to weight and jet fuel, as is apparent from a table of itineraries obtained by Univision Investiga and analyzed by experts.
You (and the "experts") might want to spend a little time studying the tradeoff of payload vs range for the RJ85 (or indeed for any aircraft):
28 Oct. Cochabamba-Medellin. Traveling empty.
The 28 October flight, for example (2800km/1510nm), is well within the capability af an RJ85 with zero payload, as were the other 3 positioning flights quoted.
Obviously the revenue flights weren't, but that's another story.
