BUG in NWA.COM
I was trying to look at fares on January 30, 2004 throuth February 7, 2004 and the nwa.com insisted that January 30, 2004 was in the past.
I assume the problem was that I was running the code on January 1, 2004 at 1:54 AM Eastern time and so we have a situation where it is not clear exactly what year it is. The code in NWA was probably in a later time zone and thought it was still 2003. That is very very cool.
