Just rode on the e190 (frontier/republic) for the first time and was seated towards the back of the cabin. I had a window seat and figured it would be nice to watch outside at night. The brilliant design of the plane has the stones on the trailing edge without any kind of reflector to protect the cabin. So unless you want to have a headache after the flight, window cover has to be closed. Poor design. Also FAs please warn the cabin before turning on ALL the lights. Sincerely your PAX.
