I flew the Q400 for the first time a few days ago from DAL to IAH and it was a horrible experience. I detailed with happened in this thread and attached a video so you can see the vibrations and hear how loud it was. Nothing would stay on my tray. THIS POST

I had an ERJ flight right after this and it was so much better. The ERJ was much quieter. The Q400 only flew at 15000 feet. We had some weird take-off departure out of DAL. I guess they had to use noise abatement procedure. We took off from 13L and cross over 13R. Normally, we fly straight over uptown and downtown Dallas. I have a detail account of Q400 on that other thread.
