A month ago my gf and I flew to from DCA to OAK. I stupidly had not bought her a companion upgradeable fare on the way there and even though there were 7 seats available in FC, we sat in the exit row. On the way back, I cleared, but declined the upgrade so we could again sit in the exit row. Honestly, the FC product isn't so superior as to be worth the bludgeoning I'd receive for leaving my SO in the back...
