Nothing--I repeat NOTHING---is worse than flying to Japan on the Freedom Bird (govt. charter) during peak summer-mover times. Dear, sweet, merciful Jesus, I was praying to die after about two hours out from Anchorage, AK. It wasn't so bad at first, because the flight left LAX at 1am, and pretty much everyone was tired and thusly, subdued. My first thoughts on boarding the ATA charter were, "Hmm. Kind of small and pretty packed... This thing's going all the way to Japan?" Things were fine up until we stopped in AK, and then, all hell broke loose.
All those families inbound for 3 year accompanied tours basically woke their toddlers up at the same time, just to piss me off. Little kids where EVERYWHERE, running up and down the isles, screaming, throwing toys, screaming, knocking over drinks, peeing themselves, and oh yeah, screaming. It was like being an illegal, stuffed into a urine-soaked container on a ship.
I did luck out on my return trip, though. Last minute orders scramble got me a seat on a JAL flight out of Kansai Intl., and a free upgrade got me into business class. Of course, I had to flirt with the most butt-ugly Japanese woman I've ever seen in order to get it, but I'm no stranger to degrading myself a little bit. And JAL business class is well worth it.
