My wife got a notice yesterday about a schedule change for a Thanksgiving Day flight. I spoke with a CSA about it on the GE/PE line today and he explained that NWA was implementing a, "major schedule change," due to lack of passenger bookings so far on 11/22. He also courteously let me change the back end of the trip to better correspond with her plans due to the inconvenience of the change. Has anyone else seen the effect of this "MAJOR" event?
