Really enjoying all of the comments on this thread. What a great idea!
I usually fall asleep not long after I settle in and wake up when the wheels hit the ground (engines are white noise for me!) so most announcements are lost on me. However on those occasions when I keep my eyes open I do like to have updates on where we are in the queue and anticipated wheels up time.
It's also nice to hear about interesting things to see. During a recent trip to PDX it would have been good for some comment on the Mt Hood/Mt St Helen's view. I knew what I was looking at having been there multiple times, but a number of the pax around me were asking each other what those mountains were...
