I was the one that posted the pics from my LAX - BOS flight. I typically fly AA25 from BOS - LAX about once a month. My last 4 trips have all been on 738s. That flight used to be on very tired 752s. Service is standard domestic first. I have never been on a flagship 762 so I cannot give a direct comparison. The 738s are pretty new and in good condition. Seats are not leather but I actually prefer the cloth. Headrests are winged to give some support. Recline is articulating. I like the laptop slot and AC power outlet. No wifi yet which is a big minus from the flagship 762s. Seats have the upper and lower pockets.

As for the cold beef, it was pretty "meh." Flavor was so-sobut it was tougher than a mule. Lentil salad was not bad. The veggie quesidilla was kinda soggy.
