24 hours, is a long time to travel.
We flew to Chicago from Louisville, but got delayed on the runway in Louisville; so we had to run in Chicago to make it to our connecting flight to Tokyo… we made it though, and started our ~11.5 hour flight.
The plane ride was fine, in that really long and tiring kinda way. We were good and stayed awake (mostly) in order to sync our sleep cycle with Japan which is almost exactly the opposite of our timezone.
