There isn't much you can do in a military aircraft since they have their own rules and regulations.
The night flights are even more secure since there have been cases where criminals with player powers and skills tried to hijack a weaponised aircraft and then threatened to crash it into a city.
The association had to take special precautions because of cases like these. They needed to make the travel as safe for the passengers as they could, meaning the people in each of these big aircrafts were still only a few.
They were given separate cabins all to themselves which were also further fortified with unique techs and magic barriers. KiRA was pretty impressed by the plane when he entered it as well as when he reached his assigned cabin.
The place was much better than first class from a reputable airline. They had made it for the special individuals who could still afford the tens of thousands of flight costs in IX.
It wasn't much for them but still, the service was good.
