The spacecraft model is too delicate to be checked baggage, or placed in the overhead bins.
An extra seat had therefore been purchased. Hayabusa2 would sit beside me, and take the chicken for dinner.
Or... neither of us would fly.
It transpired the extra ticket should have been purchased as a "cabin bag ticket", not as a "human-be-flying ticket".
Now you'd think as the latter is more expensive, and the seat clearly reserved in my name, this wouldn't be a big deal.
OH SO WRONG.
In typical Japan style, the airline staff were lovely and went out of their way to try and fix this issue.
But over their dead bodies would a model take a seat reserved for a human.
The original ticket (not purchased by me) had to be refunded. An ENTIRELY new baggage ticket must then be bought (by me).
Concern 1: what if the new ticket --due to its last minute nature--was more expensive than the original? This should really be discussed but the clock was ticking ⏰
