I think I've done a total of 33 flights in my life, counting each leg of a trip separately. counting them as one time per return trip that averages out to once every third year, roughly. most of those could have been done by ferry or trains, but would have take far longer and cost way more. The cost aspect is the big lever we need to use IMO. Per-flight tax that goes up for every flight you take (per year, I guess). Ban freq.flyer miles etc.
