Business clients wouldn't mind that much. But it would kill a good chunk of tourism industry (and good riddance). Tickets for leisure flights are ridiculously cheap nowadays.
I'm taking the train for my next holiday and it is significantly more expensive. Flying is unreasonably cheap. Aviation fuel needs to be taxed but this has to be done everywhere to avoid refuelling in havens. Or maybe tax stands at airports if that can't be done.
Jets are not going to tanker fuel in significant quantities over anything approaching a reasonable level of taxation differences. It would be extremely rare for a medium-haul jet to even be able to tanker fuel for a round trip and impossible for any of the long-haul routes.
