Thanks for all the comments on my question. I am not sure the 5:15 was worth the change to the 2 hrs. Being only available after 1200 was very nice and now that it is 10 it isn't as nice and of course that is only if they get it on your schedule before 1500. I did hate flying and having two different numbers for a line holder and a rsrv though, so the 5:15 will be very nice.
I am still confused on how you can know something is on your schedule if you don't have to check your schedule and they don't have to call you. I didn't ACK my trip so I wonder if they will call me at 0000 or not but since we don't have to ACK trips anymore I doubt it.
