Summary: Ramón Vallés, a Level captain, breaks down in a video the fuel calculations behind a long-haul flight between Barcelona and Buenos Aires.

## Article

A **Level** captain, Ramón Vallés, has posted a video on social media walking through the numbers the crew handles before a **Barcelona-Buenos Aires** departure, as reported by [Preferente](https://www.preferente.com/videos/un-piloto-desvela-el-brutal-consumo-de-combustible-en-un-barcelona-buenos-aires-352143.html). This is not a fun fact. It is the fine print of how a long-haul flight gets planned today.

Vallés goes over fuel calculations, cargo weight and the buffer kept aside for diversions or holding. On a route that long, every tonne matters and the captain decides what goes on board before signing the flight plan. There is no room for improvisation there.

The useful takeaway for the industry is simple. On long-haul routes, efficiency is not fixed on the ground with a good ticket price. It is played out in weight, cruise altitude and weather. I see a lesson here for revenue and for operations, because what the passenger pays up front starts being decided down in the hold and in the tank.
