I dont think that it will be so much faster and better to travel with aircrafts whith everything around it. First it will cost more secondly when everything is realistic you would have to check in, wait etc. etc. etc. This would also make a lot of jobs and would require catering companies and so on. I think it would improve the game as long as it is taking seriously and professional. Also if they expand the map to more islands it is more than necessary.
