American Airlines Boeing B737 800 seat review by webjetter #30396

American has reduced the amount of space in bulkhead on this aircraft and you are much more squished in.
The 'entertainment' is directly above your head, so you might get uncomfortable watching.
I was very lucky that the middle seat stayed empty, so it was quite comfortable. You MUST board first because you will need the overhead storage for your belongings. You can hold a very small bag and maybe your ipad, but the FA's will make sure you are not holding too much. How much is too much varies by FA. Remember, if you book this seat and B/C are booked in a flight with empty aisle seats further back, that means the travelers are together. You will probably have someone in the middle seat. Also, in a route where there are lots of children (or seasonal) you may have lap or small children next to you. Bulkhead is popular for people with lap children.
PS... this aircraft has some new interiors and some retrofitted interiors. IMO, the new planes are much more comfortable than the retrofitted ones.
