Didn’t receive current survey. Received survey and was invited to try 4 new domestic FC prototype seats in Willis Tower a few years back as a Premier 1K. Cocktails and hors d’oeuvres were served. It was a fun event with dozens of other pax and reps from the seat manufacturers. I respect UA’s approach - my only disappointment with the outcome is the headrests don’t tilt forward like they used to do on A319/A320.
