This is a tough one, it would depend on the flight time. If we are jumping over to Vancouver for a game, that is a 25 minute flight. I might throw on an episode of Demon Slayer or Big Mouth to pass the time. Typically it is chatting up with my linemate Kevin Kim and going over strategy for a short flight.
Longer ones like Maine or Carolina we could spend 5 or so hour in the air, those ones I typically read a book. I have finished a Song of Fire and Ice, unless more finally get made. I am starting another fantasy series The Green Bone Saga, so far it is turning out really good.
