Yes, if you’re on the right radio frequency.
I meant as a passenger. I'm always aware of times when I fly, probably because I always seem to have to make a connecting flight. I'm also very aware of when we prep for descent, which should occur about 20 minutes out.
Since there was no descent prep at 20 minutes out, and they kept flying an additional 20 minutes beyond the destination, that is 40 minutes for someone to raise the question - certainly someone should have noticed.
