Asians have no need for personal space - and when your on shuttles that take an hour in flight time - how is it that much different than taking a train in the city ?
Won’t be too long until we are able to fly between NYC and London in 3 hours or less soon. Can definitely see this catching ok in “value conscious” countries.
Who knows - might even see ICE Airlines adopting it as a cost saving move by DOGE.
