Rode in one of these planes yesterday. Luckily I didnt have to deal with the small bathrooms in coach but I did find the lack of bulkhead bewteen F and Y really annoying. My favorite seat has always been 6E but now not so sure about it now. I did like the larger bins though, but also find that under seat storage in F has been greatly reduced due to seat design. Wrote to AA and did get a somewhat personalized response which I'm posting here for anyone who's interested:

"Hello Mr. FAA1996:

Thank you for writing us. As one of our valued AAdvantageŽ Executive Platinum customers, you are well qualified to judge our service. Your comments are a trusted means of identifying those areas which require our attention. Naturally, we are concerned that your experience with our reconfigured Boeing 737 aircraft has caused you to question our commitment to high-quality service. We are sorry for your disappointment.

On the inside of the Boeing 737 MAX and our reconfigured Boeing 737-800 aircraft, we offer wireless entertainment to deliver a complimentary library of movies, television shows and other entertainment to our customers' phones and tablets, and tablet holders in the seatback to hold those devices. Unlike quickly outdated in-seat screen systems, we know our customers carry the latest tech. In addition, we know how important it is to stay charged and connected, and the MAX features power at every seat as well as fast ViaSat satellite-based internet connections for a fee. I also regret that the enjoyment of your flight was diminished by the removal of the bulkhead separating the Main Cabin from the Premium Cabin.

As a loyal customer, we care about what you think of the way we do business and thank you for your feedback. Your comments have been documented and made available to the right people here at American for internal review. We try to be responsive and look for trends based on your reactions to different areas of service. This helps us to identify the different features that are most appealing and improve those that aren't so popular.

Thank you again for writing us Mr. FAA1996 and for your loyal participation in AAdvantageŽ since 1999. It's our goal to suit the needs and wishes of the largest group of our customers. As we look to make changes, you can be sure we'll keep your concerns in mind. Thanks for giving us the benefit of your invaluable observations and we look forward to welcome you aboard again soon.

Sincerely,

RC
Customer Relations
American Airlines"
