I am spoiled by BA F! Unlike the naysayers here, I've never had a bad experience and have had some really memorable flights! Why not get the long haul to SEA or SFO or PHX or LAX - that to me is the real F experience. Go for it! Be sure to have time to enjoy the CCR and the free treatments in the Elemis Spa (book ahead). I love the cabanas when I am connecting at LHR on a TATL but never get one when departing London - not worth it.

Have a great trip!
