Got the double-beep at the gate and thus the op-up from WTP to CW from LHR-SFO today. I'm an AA EXP/OWE. J cabin was fairly empty so they were moving people from awkward seat options (ie window/aisle pair and honeymoon seats) if they were traveling alone to other seats. Had the whole lower-floor 744 honeymoon seat pair to myself, which was wonderful - one seat for sleeping/napping and the other to take meals, a great big cocoon. WT was fairly open too; just WTP was oversold by 6-7 seats. Explains why the quoted AUP was so low at 405 pounds
