For the past 10 years I have taken Delta from BOS to SLC for ski weekends and to attend the Sundance Film FEstival. I have always taken the direct 6:30 am departure out of BOS and returned on the 5pm departure out of SLC. These flights are always full, but some reason DL is not showing these flights for winter 2012. Currently their is only a 4pm BOS-SLC and a 10ish am SLC-BOS. Have hey just not loaded their winter schedule yet? If not, do you know when they typically modify their schedule for the winter months? For DL to cut these flight times from their schedule would blow my mind. Always full flights and full of a lot of skies because you would get to SLC at 10 am, be on the slopes at noon and on the return you could ski till 1 or 2 and make your 5pm back east. Any help or knowledge regarding DL scheduling would be greatly appreciated.
