AA 777 LHR to ORD. Another full fight with the choice seats taken. Took a peek at SeatGuru.com and gave seat 40J a try. 40J is not a bad seat, a little extra leg room and the seat in front of you does not recline into your nose. You can open your laptop in this seat and use it without contortions. The downside is that you have the entertainment electronics at your feet, pick the aisle 40I if this is a bother. The J seat is nice since you can look out the window and you can lean to the right to sleep.
