> It seems to me that the hub and spoke model would have been a lot more environment friendly. I would think it's the opposite, with more takeoffs and landings, and more miles traveled. A380 IIRC has higher fuel consumption per passenger than the latest generation twinjets (B787 & A350), but probably a new generation superjumbo could close that gap if there were a need for such a plane (which currently it doesn't seem like). > I think governments should tax airlines for their emissions. Absolutely. We need to drastically reduce flying. Most governments talk about the need to reduce emissions, but guess who received hundreds of billions of COVID handouts? Yup, airlines. A huge opportunity to instead invest in low-carbon infrastructure wasted..
