The food was outstanding, booze was great, and the seats.......I really don't know how to describe how comfortable they were. Flight #1/4 (CMI-ORD/ORD-CMI): the boring part of the trip, quick 25 minute flight on an Embraer on American Eagle. Nothing much to speak of.
Flight #2 (ORD-LHR): This was my first First Class experience and I loved it. Unfortunately this flight was not operated by one of AA's 777's that has the flagship suites, but still, after riding in steerage for 21 years, this seat was awesome!!! I had a 4 course dinner (not including the cocktails and nuts served before hand) plus a well rounded breakfast prior to landing (Filet Mignon, chive cream cheese omelet, fresh fruit, black coffee, fresh orange juice....) The wine selection was extensive (3 whites and 2 reds plus champagne and port). They had a decent selection of movies (over 15) plus all the music and other mumbojumbo....
Flight #3 (LHR-ORD): The flagship suite!!! This thing was comfy!!! If it were a red-eye flight I could see myself sleeping soundly in this seat!!! Service was very high quality comparable to the other flight across the pond.
Overall I now consider myself to be spoiled. I don't know if I'll ever want to travel on long flights in coach again after being pampered like this!!
I did kind of feel sorry for the people in coach, seeing is how I am one of them at heart. Trip cost for me was less than $400, realtime cost for non-AA employees ~$14,000. Just one of the benefits of working for the largest airline in the world.
