I was booked on a flight from LGA-MSP-LAS on 1/7/05. I was upgraded to FC for LGA-MSP earlier than the 24 hour window for Silver elites. On 1/6/05 I was checking my itinerary, on nwa.com, to see if I was upgraded on MSP-LAS, and noticed that LGA-MSP was listed as CANCELLED. I phoned CS and found that I was moved to flight 1199 a direct LGA-DTW-LAS and was put in FC for the whole trip . During my phone call I asked why I hadn't been notified; their response was that they phoned me. I did not receive a message on my answering machine. Looking at my caller ID device, I did see a call.
[I saw my upgrade on nwa.com for my original flight, and they called me the next day, but I had to press some key on my phone to retrieve that message--I assume the cancelled flight required the same input.]
After 1199 departed I found an e-mail,. notifying me of the change...this seems like a screwy system.
