The first time i switched to it to avoid the red-eye. The second time i did the same plus to get some miles back as it was a saver award and go sightseeing. I cant stand red-eyes.

Lucky for me, there was a couple on their way home from JNU on the shuttle so they held it past 2AM this time. I felt worse for them though. They were scheduled on the 9ish am SEA-BOS flight but missed it due to mechanical in JNU.
