@estelle yeah i don't think anybody tried it since, and even at the time it was probably a publicity stunt? wasn't it done by ryanair

@whitequark i had to look it up, it appears to have been started by samoa airlines in around 2013 (has it been that long?), and cnn circa 2023 says united airlines and others require buying two seats, but may refund it if empty seats are available

fox news (ugh) outright states in their article that "1% reduction in weight would save 0.75% the fuel consumption"

canada appears to have a "one person, one fare" law for airliners

(i have not flown in an airliner for a very long time)
