SFO on 8/6 - not myself but another traveler, BP indicated C-class so I'm assuming he was headed to JFK started arguing with the TSA (?) rep at security who seemed to be on the look-out (only say that due to TEAM SFO moniker on her badge strap). Felt bad for the fellow - the bag looked big but knowing the 762 bins it wouldn't have made a wink of difference, especially up in C. Thought of speaking up but held my tongue.
LAX on 8/10 - gate agents seemed to be incredibly vigilant on the way up to SFO, questioning almost everyone coming through with FC.
