Depending on their financial and partner situation, I may shift more business to US next year. Suddenly I find myself travelling to the East Coast more, and it can be difficult to do a same day round trip on NW, simply because their service isn't as frequent. US has a ton of service CAK-PIT feeding the PIT hub, so I can get just about anyplace on the east coast for a day. AA wants me to fly to ORD or JFK to connect, and only from CLE. Biggest drawback to US is that they never restarted the promised PIT-PDX service...
