On yesterdays CDG-SFO 767, the FA's blocked the aisle in front of coach with carts and taped hand-written notes on the lav doors saying they were only for biz class pax.

While I'm in favor of keeping nosy coach pax from running up to C and F, I think it's petty to stick a cart in the aisle and tape up a cheap sign on the lav doors. It obviously doesn't have anything to do with security since the biz and first pax didn't have any blockades on their way to the cockpit door. They should do like BA and use a red rope.

Ah, the joys of flying a bankrupt airline.
