My dates are the 10th through the 20th, and I noticed that the prices with airline codes, etc, went down about 1.5 weeks ago (or maybe not so long, maybe longer...I posted here about it when I noticed it, though). It's still really high, but not AS high.
For those looking at National, have you looked into the KLM/Air France/Flying Blue program code? I joined KLM/Flying Blue the other night and found the code in their "partners" section, and it brings the price in the lowest and includes things like loss damage waiver. It seems to be a good code, and like I said it's there on their website when you join their program and are logged in. The only issue is that you can't modify a reservation with it online; you have to call.
