When flights are overbooked, airlines move some lucky people from economy to business class. I always thought I’d grow up to be the sort of guy who got upgraded – someone you can trust in the front of a plane.
I’m still waiting.
After reading new analysis by Oxford academic Milan Klöwer, I may just give up the dream entirely. Klöwer researches simple things airlines could do to massively reduce their emissions, right now, without waiting for miracle fuels or electric planes. His most eye-catching finding? Scrapping business class altogether could dramatically cut emissions per passenger mile.
His argument is simple: fuller planes mean fewer flights. This is why budget airlines often outperform their fancier rivals on carbon efficiency. And it’s why my long-imagined upgrade would come with a downgrade for the climate.
Andrew Mountbatten-Windsor last week became the latest in a long line of royals to be arrested. Gonzalo Velasco Berenguer, a historian at the University of Bristol, looks at a practice that was fairly common throughout English history – until the past three centuries.
At least the remaining royals have fairly AI-proof jobs, right? After all, AI is coming for my job – and perhaps yours too. But Abigail Marks, a professor of the future of work at Newcastle University, says this fear of replacement is already damaging worker wellbeing – before any actual mass unemployment. She looks at how to combat AI-anxiety in the workplace.
