Can't say I had the same experience as the OP.

Just returned from ORD-LHR in First Class and had an experience consistent with all prior 777 Flagship trips to LHR (at least 5) which is why I choose AA - then having the miles to do it with Mrs. FrAAmer annually helps.

I usually fly LAX-LHR as I prefer to be on the plane longer so I can get a full 7 hours sleep plus dinner/movie. ORD- LHR is just too short - though the crew was friendly, attentive and supportive. There were 3 empty seats in First Class plus the crew seat - and Mrs. FrAAmer was the only woman passenger. And, at least 3 of the other passengers opted for no food service and went to sleep as soon as we took off so lots of crew attention, service from the carts, wine label presented at pouring etc.

Flagship lounge at ORD was excellent as were food offerings (huge shrimp).

I guess I am just loyal to AA and resign myself that Flagship on a 777 is the best they have to offer, and for an award ticket, I can't complain.

Since I have lots of AA miles, is there a "better" way to get to Europe in First Class using only AA miles?
