From what I keep hearing 1500 is normal price now the whole 900 thing is gone >_> I know that domestically while flying for work lately it's been very expensive... I'm going to use the train for my new england travel between cities because i was seeing prices of like $400-$500 to fly one way between boston and philidelphia booking 2 months in advance O_O so i took the $175 train ticket instead!!

I think you should totally buy the $1500 especially going out of smaller airport in your city instead of Tokyo... I don't think airfare is going to drop between now and christmas maybe after christmas/new years but not before this is some of the most busy travel time around the world no reason to drop fares yet!

I think if you wait you'll end up paying more to go out of tokyo >_>
